Service Conditions

For service from –20°F to 650°F (-29°C to 345°C). This material must be quenched and tempered to obtain tensile and impact properties needed at subzero temperatures.

(1) Upon prolonged exposure to temperatures above 800°F (426°C), the carbide phase of carbon steel may be converted to graphite. Permissible, but not recommended for prolonged usage above 800°F (426°C). (2) Flanged end valves rated to 1000°F (537°C). (3) Considerations should be given to the possibility of excessive oxidation (scaling) when used above 1050°F (565°C). (4) Product used within the jurisdiction of Section 1 Power Boilers of the ASME Boiler and Pressure Vessel code is subject to the same temperature limitations as specified in that document. (5) Product used within the jurisdiction of Power Piping, ASME Code for Pressure Piping B31.1, is subject to the same maximum temperature limitations placed upon the material in paragraph 124.2.

Warnings 1. All Pacific® Valves are designed and manufactured to be installed in applications where no more than 1g of force in excess of gravity is applied to the valve in any direction. This 1g force can be an effect of Traffic, Wind or Earthquake. Pacific® valves should not be used in applications that exceed 1g.

6. When operating any valve stand clear of any moving parts such as the stem and/or disc assembly.

2. All piping system components are subject to certain levels of erosion and corrosion. As the valve wall thickness is the governing variable in overall service life,care should be taken to ensure that all valves and related piping components are of a suitable wall thickness for the given application. Periodic inspections should also be made as valves/components may wear over time.As a minimum, annual inspection of the Body and Bonnet wall thickness should be performed with calibrated measuring devices such as micrometers and/or ultrasonic thickness gauges. Severe applications may require additional inspection types and/or frequency. Additionally, valves should be inspected for general signs of component wear and/ or damage caused by process media, i.e. steam cutting. This may include the removal of insulation and/or other coverings to ensure a proper inspection. All valves should also be cycled completely during these inspections to ensure proper operability. Care should be taken to ensure that this will not affect the operating system.

8. Motor operated valves should be left in their factory set condition, unless the system operating parameters dictate a change.If changes are necessary,they should be performed in small increments and then the valve operation inspected. When adjusting these settings, use only the lightest/lowest setting possible to achieve the desired performance. Excess torque and/or thrust in the motor settings, may damage or lockup the valve. Never remove a motor operator, gear operator or manual operating assembly from a valve while it is pressurized. The valve must be completely relieved of all pressure prior to this disassembly.

3. All Pacific® valves are designed for operation in clean media. This media should be free of all debris and particulate matter. Debris in the media may cause damage and/or reduced performance to the valve. 4. The style, size, pressure class and material selection of all valves are the responsibility of the piping system designer. Pacific® may offer suggestions in this area, however the selection process is solely the responsibility of plant designers. Plant designers should also take into account the specific effects that the process media will have on the valve wall thickness and corresponding service life and ensure that the selected material is compatible with the process media. It is the responsibility of the piping designer to ensure that valves are equipped with any necessary venting and/or draining capabilities. 5. Do not exceed 100% of the maximum pressure rating of the valve at any time during its operation. Pressure spikes beyond the valve’s pressure rating are solely the responsibility of the user.

4

Crane ChemPharma & Energy

7. All manually operated Pacific® valves are designed to be tightened by hand only. Do not apply excessive input torque via pipe wrenches“cheater bars”or other devices.

9. Care should be taken to ensure that electrical motors are wired correctly to the power source. Incorrect phasing of 3-phase wiring may cause valve/motor damage. 10. The operator of any valve should have an understanding of the effects of opening/closing the valve with regards to its role in the overall piping system. Operators of valves under pressure should take caution to ensure that the valve is in good operating condition prior to operating it under pressure. 11. Certain valve applications take place at elevated temperatures. Care should be taken in these instances to ensure that an operator does not touch any portion of the valve other than the handwheel. In severe temperature applications (300°F and above), insulation may be required on the valves to protect operators from the heat. 12. Certain processes utilize flammable, caustic and/or otherwise unstable media. Care should be taken in these circumstances to ensure the operator is aware of the specific health and safety risks associated with that medium. 13. All Pacific® valves should be operated within the pressure and temperature ranges listed in Table 2 of ASME B16.34. Under no circumstances should the valves be operated at conditions outside these tables.All piping systems should contain independent support mechanisms and should not utilize the valve as a sole means of support.

www.cranecpe.com


Warnings 14. The estimated total lifespan of a PacificÂŽ valve when installed within ideal boundary conditions is 20 years, however, this lifespan may vary widely dependent upon operating conditions. 15. All valve actuators shall be sized by referring to the specific relevant valve torque and thrust data published by PacificÂŽ. Generic or standard valve information shall not be used. 16. It is the ultimate responsibility of the piping designer to ensure that each valve is sized appropriately for the given system parameters of pressure, temperature, flow rate, velocity, pressure drop, etc. and that the proper trim is specified for the system design parameters. Additionally it is the responsibility of the piping designer to ensure that the corresponding actuator sizing data is correct for the given application. 17. Valves other than globes should not be used for throttling applications. Severe damage may occur to other valve styles. When using globe valves for throttling, do not operate the valve continuously at less than 10% open. 18. All valves shall only be used within their defined boundary conditions. All standard materials of construction, including bolting are suitable for operation within the boundary conditions listed in Section 8.0 of this document. Care should be taken to ensure that all valves are not operated at conditions that exceed or deviate from the defined boundary conditions. The boundary conditions must be adhered to regardless of the piping system status, including but not limited to: Start-up, hydro-testing, chemical cleaning, system flushing, etc.

22. It is the responsibility of the user/owner of a plant to ensure that all valve operators are ordered to meet all applicable requirements and specifications. 23. Only valves that have been certified as fire safe shall be used in piping systems that may be exposed to fire. 24. Low Emission Packing is suitable for 100 ppm. Standard graphite packing is available, but valve will be in accordance to API 600 12th edition. 25. When operating manual valves, gloves should be worn to minimize the risk of injury to the hands. 26. In situations where manual valves are difficult to operate due to substantial torque requirements, it is recommended that the valve be supplied with a gear or motor operator. 27. All valves should be mounted with the stem vertical and the pipeline horizontal. Check valves may be installed in vertical pipelines only when the normal flow is in the upward direction. For any other orientation, please contact the factory. 28. Depending upon the specific application, normal lubricants may not be sufficient for higher temperature applications. In this case, higher temperature lubricants should be used in place of the standard type. 29. All valve packing glands should be tightened in an even manner. Care should be taken to ensure that the packing gland and/or gland flange do not contact the valve stem or stuffing box during tightening.

19. Valves are not suitable to serve as block valves during system hydrostatic pressure tests that exceed 1.1 times the cold working pressure. 20. Care should be taken around all valves as injury or damage may occur from the leakage of hot, high pressure and/ or caustic materials from a gasket and/or packing joint. Additionally, packing and/or gasket leaks may cause external corrosion damage to the valve. 21. When possible, gate valves should be relieved of maximum seating force when left in the closed position. By relieving this force, it may help prevent damage caused by excessive thermal stem expansion. Care should be taken however to ensure that the valve is not opened, only that the torque/thrust has been removed from the stem. www.cranecpe.com

General Valve Operation & Maintenance 1.0 THEORY OF OPERATION

GATE VALVES | Gate valves are designed to close off or open up the flow in a pipeline. The wedge is designed to completely stop flow and form a tight seal against pressure in either direction. In the open position, the wedge is completely out of the flow stream. Gate valves are not recommended for throttling use. GLOBE VALVES | Globe valves are designed to close off, open up or throttle the flow in a pipeline. The disc is designed to completely stop flow and form a tight seal with pressure under the disc. In the 10% open position to full open position, globe valves are effective in throttling line pressure. NOTE: Continuous throttling at less than 10% open may cause excessive vibration, noise, wear and damage to discs and seats. CHECK VALVES | Swing check valves are designed to open by the system pressure in a line. The normal direction of flow in the line will open the valve, and any attempt by the flow to reverse will close the valve completely. The check valve typically does not require any outside force or signal to operate properly. Check valves allow flow in one direction only.

2.0 DESCRIPTION

This manual covers all Pacific® bolted bonnet valves. These valves are designed within the limits of ASME B16.34, API 600, API 623, and API 594. For the Operator and Mounting Topworks of these valves, the user is referred to the applicable Section in this manual. See Section 5.0 for Operation of Valves. This manual is for reference purposes only. Disassembly and maintenance of valves should only be performed by qualified personnel. Consult Pacific® for specific technical support. For Specific information regarding a particular style of valve, please refer to the corresponding detailed Section.

3.0 INSTALLATION

When unpacking, care should be exercised in lifting and handling to avoid damage to valves or injury to personnel. Do not lift any valve by the handwheel or stem. Use lifting lugs or straps around the valve body. For specific Installation Information, please refer to Section G of this manual. When installing, ensure that all foreign material is removed from the interior of the valve, including desiccants. NOTE: Do not remove protective end coverings until immediately prior to valve installation. NOTE: Do not disassemble or modify a Pacific® valve in any way prior to installation. This will void the factory warranty if it occurs. When installing flanged or ring joint end flex wedge gate or globe valves into the line, it is advisable to have the valve slightly open to prevent the wedge from becoming “stuck” due to thermal expansion and to discourage damage to the seating surfaces. There is an exception to this with Butt-weld end valves, they should be installed in a lightly closed position. See Valve Installation Section G. A protective paint may have been applied to the weld ends on some valves, and it should be removed before welding, unless it is a deoxaluminite paint which acts as a welding flux and does not need to be removed. Use the smallest electrodes and the minimum amperage possible consistent with approved welding procedures. This will help to minimize warpage in the seat areas. Tack welds should be ground out before completing the root pass in that area. Valves of carbon steel should be allowed to cool slowly. The valve may be covered with a heat-insulating blanket to promote slow cooling and limit the heat-affected zone. Appropriate industry standards should be followed for all PWHT. Certain valve types are designed to function in a single direction (check valves, etc.) All markings should be noted on the valves. Arrows on the valves indicating flow direction should correspond with the system flow direction. NOTE: Ensure that all foreign material (dirt, weld slag, rocks, wood construction materials, weld rod, etc.) has been removed from the valve prior to and after installation. Foreign material is the primary cause of premature seat failures.

4.0 WARRANTY

All Pacific® valves are backed by a full manufacturer’s warranty against defects in materials or workmanship. It should be noted that any work or modification performed on a Pacific® valve must be authorized by Pacific® in order to retain the original factory warranty.

General Valve Operation & Maintenance 5.0 OPERATING INSTRUCTIONS

Pacific® valves are designed for simplicity and ease of operation. To open a gate, globe, or stop check valve, turn the handwheel in a counterclockwise direction; continue turning until interference is felt; at this point, the valve will be fully open. To close the valve, turn the handwheel in a clockwise direction; continue turning until interference is felt; at this point, the valve will be fully closed. Swing, lift and tilting disc check valves are designed to be operated by line pressure only. When the upstream line is pressurized, flow will open the disc. When the pressure is reduced upstream, or if there is backpressure, the disc will close. With some larger valves under conditions of high pressure, a rim pull of more than 250 lbs. may be required to achieve proper seating.CAUTION! - These valves were designed to operate within the pressure and temperature limits of ASME B16.34. Do not exceed these limits.

6.0 MAINTENANCE Item to Inspect Check Stem threads for wear Check for Packing leaks Check body/bonnet joint for leaks If conditions permit, operate valve Inspect all external connections Ensure Stem and seal areas are free from debris Check all lubrication points Inspect condition of motor and/or gear operators (when used) Inspect valve for obvious damage

6.1 PREVENTATIVE MAINTENANCE AND PERIODIC INSPECTION Pacific® recommends that periodic inspections be made of all valves. The frequency of these inspections will vary, depending upon the severity of service and frequency of operation of the valve. As a minimum, all valves should be checked quarterly to ensure proper operation and discourage the damage compounding effects of leakage. The following list details the specific valve types and areas requiring inspection and maintenance. Warning! Do not remove or loosen the packing gland or bonnet bolts while the valve is pressurized.

6.2 MAINTENANCE OF VALVE UNDER PRESSURE If the above listed inspections reveal any indications, the following procedures are recommended: NOTE: Extreme care should be taken when working on any pressurized system! 6.2.1 If the stem packing is leaking, the eyebolt nuts on the gland flange should be tightened uniformly until the leakage stops. If the leakage continues or there is no adjustment remaining, additional packing must be installed or the packing must be replaced. (See disassembly procedure for appropriate Valve or Packing and Gasket Maintenance Section H) It should also be noted that the valve should be able to operate freely at all times. If the valve cannot operate due to excessive packing force, the packing has become worn and must be replaced during a system shutdown. 6.2.2 The stem threads that are exposed to atmosphere should be periodically lubricated to reduce wear, operating torque, and to deter corrosion. Care should be taken to ensure that only the threaded portion of the stem is lubricated. Pacific® does not recommend the practice of lubricating the sealing area of the stem, in the absence of lantern rings or with the exception when lantern rings are installed. This practice tends to attract debris and foreign material, which can lead to stem or stuffing box damage. 6.2.3 The yoke sleeve should be lubricated periodically through the grease fitting to ensure smooth operation. Lubrication should be inspected and revised at each application. Each installation may have specific requirements/ specifications regarding lubrication. 6.2.4 If leakage develops at the body/bonnet joint of a bolted bonnet valve, the bonnet stud nuts should be tightened uniformly. This tightening should be done in accordance with the Bolting Torque Section E of this manual. CAUTION! Do not overstress the bolting. If leakage continues, the gasket should be replaced. (See the Bolting Torque Section E or the appropriate valve disassembly procedure.) 6.2.5 If normal inspection reveals a binding or galling action of valve operating parts, it is advisable to dismantle and inspect the valve parts during a system shutdown. Contact Pacific® prior to disassembling any valve. www.cranecpe.com

Bolting Torque Data

SECTION E Bolting Torque Valves

Crane ChemPharma & Energy

www.cranecpe.com


Bolting Torque Data 1.0 GENERAL INFORMATION For General Valve Operation & Maintenance Information please refer to Section A of this manual. This Section details the specific torque values recommended by Pacific® for bolting used in all Pacific® products.

2.0 STANDARD PROCEDURES CAUTION! The torque values in this section only apply to the body bonnet joints and flange joints. Please reference section H for packing torques. 2.1 | Always use new bolting materials. 2.2 | Verify that the materials are compatible with the process system as well as any temperature or pressure requirements. Note that bolting materials can have minor identification changes which may have a substantial impact on performance, ie. B7M vs. B7. 2.3 | Whenever allowed by system and process parameters, use appropriate lubrication to ensure even tightening of the bolting materials. For higher temperature applica-tions, the use of an “Antisieze” compound may be necessary to promote future disassembly.

3.0 ASSEMBLY AND MAINTENANCE OF FLANGED JOINTS When a flanged joint is assembled, each of the component parts in subject to tensile or compressive stresses of varying magnitude. In the great majority of cases, it is adequate to tighten the bolts sufficiently to withstand the test pres-sure without leakage. The maximum allowable stress values for bolting given in the various codes such as ASME Boiler and Pressure Vessel Code and the ASME Code for Pres-sure Piping are design values to be used in determining the minimum amount of bolting required.

greater than the design value therefore must be provided. If it is not, further bolt strain develops during the test which tends to part the joint and thereby, to decompress the gasket enough to al-low leakage. It is evident that an initial bolt stress higher that the design value may, and in some cases must, be developed in the tightening operation. This practice is permissible, as pointed out in Appendix S, Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code, provided it includes necessary and appropriate provision to insure against excessive flange distortion and gross crushing of the gasket. Investigation of field-erected flange joints has indicated that the probable bolt stress developed manually, when using standard wrenches on alloy steel bolts is:

Where S is the bolt stress and d is the nominal diameter of the bolt. Experience indicates that these stresses are satisfactory for ASME B16.5 flanges and will comply with the requirements as set forth in the preceding paragraphs. It can be seen that smaller bolts will have excessive stress unless judgement is used in pulling up on them. On the other hand, it will be impossible to develop the desired stress in very large bolts by ordinary hand wrenching. Impact wrenches may prove serviceable, but if not, resort may be had to such methods as preheating the bolt or using hydraulically-powered bolt tensioners. With some of these methods, control of the bolt stress is possible by means inherent in the procedure, especially if effective thread lubricants are employed, but in all cases, the bolt stress can be regulated within reasonable tolerances by measuring the bolt elongation with suitable extensometer equipment. Generally, simple wrenching without verification of the actual bolt stress meets all practical needs, and measured control of stress is employed only when there is some special or important reason for doing so.

A distinction must be recognized between the design value and the bolt stress that might actually exist or that might be needed for conditions other than the design pressure. The initial tightening of the bolts is a pre-stressing operation, and the amount of bolt stress developed must be within proper limits to insure, on the one hand, that it is adequate to provide against all conditions that tend to produce a leaking joint and, on the other hand, that it is not so excessive that yielding of the bolts and/or flanges can produce relaxation that also can result in leakage.

It is possible for the bolt stress to decrease after initial tightening, because of slow creep or relaxation of the gasket, particularly in the case of the “softer” gasket materials. This may be the cause of leakage in the hydrostatic test, in which case it may suffice merely to retighten the bolts. A decrease in bolt stress can also occur in service at elevated temperatures as a result of creep in the bolt and/or flange gasket material, with consequent relaxation. When this results in leakage under service conditions, it is common practice to retighten the bolts, and sometimes a single such operation, or perhaps several repeated at long intervals, is sufficient to correct the condition.

The first important consideration is the need for a joint to be tight in the hydrostat-ic test. An initial bolt stress of some magnitude

Long Term Storage of Valves 1.0 GENERAL INFORMATION For General Operation & Maintenance Information regarding for valves, please refer to Section A of this manual.

2.0 STORAGE The following recommendations are for preparing valves and their accessories for Long Term Storage. They are necessary to maintain the valves in proper condition prior to installation into the pipeline. By following these procedures, abrasive and corrosive substances can be prevented from affecting valve performance. It is the purchaser’s responsibility to take the necessary precautions for the protection of valves in storage. 2.1 AS SHIPPED CONDITION | Valves are packaged with a moisture resistant closure on the valve ends. Where size permits, plastic plugs or caps are used. On larger size valves, wood covers are sealed with tape and securely attached with metal bands. On valves with pipe flanges the wooden covers are secured with bolts. All other openings are covered with plastic caps or plugs. Parts packaged separately are secured in packaging from the factory to prevent damage during handling and storage. These parts are to be stored off the ground in an area protected from the weather.

Slight external rusting may occur on valves stored outside. This will have little or no effect on their performance. If units are stored for more than 6 months we recommend that gate and globe valves be cycled open to close every 6 months to keep the packing from adhering to the stem and to help lubricate the stem and yoke. Heavy internal rust however, may be harmful and must be corrected. 2.4 PREPARATION FOR INSTALLATION INTO THE PIPELINE | Inspect valves as per the above instructions and remove any contamination, assuring that the valve is clean and dry. Re-torque all bolting to factory specifications to compensate for possible bolt relaxation, which may occur during long storage. Ensure that all foreign material has been removed from the valve.

2.2 RECOMMENDED STORAGE FACILITIES | The following are a list of storage types in order of most preferred to least preferred: 1. Enclosed weather tight building with a concrete floor. Enclosed building with a dirt floor. Valves must be on pallets. 2. Open air, valves on pallets on a concrete floor covered with a tarpaulin (this is not recommended for more than six months) 3. Open air, valves on pallets on a dirt floor and covered with a tarpaulin (this is not recommended for more than six months) 2.3 INSPECTION | Periodic inspections should be performed on all stored valves and parts. The frequency of these inspections should be determined by the type of storage facilities and weather conditions. At a minimum, all parts and valves should be inspected every 4-6 months. Inspect for dirt, moisture or any other type of contamination. If any is found the valve is to be thoroughly cleaned and dried. Repeat the above listed packaging procedure to ensure the valve is weather tight. www.cranecpe.com

Valve Installation GENERAL INFORMATION For general valve information, please refer to Section A of this manual.

1.0 INTRODUCTION By exercising proper care in the installation of Pacific® valves, the probability of trouble-free service will be enhanced. It is important to recognize that in the transport, handling and storage of a valve between the time of manufacture and the time of installation, there are numerous possibilities for accident or error, which may affect valve performance. All valves should be handled/installed in such a manner as to comply with all applicable state, local and federal safety regulations including, but not limited to OSHA regulations. Personal Protective Equipment (PPE) should also be used in compliance with all regulations.

2.0 INSPECTION AND HANDLING Before installation of the valve, it is important to determine that the valve is in satisfactory condition. It may be helpful to observe the following points, in order to avoid subsequent valve problems: 2.1 | Carefully unpack valve and note any special warning tags or identification plates attached to the valve; take appropriate action. 2.2 | Check the valve for any markings indicating flow direction. If flow direction is indicated, appropriate care should be exercised to install the valve in the proper flow orientation. Check valves and non-return valves are uni-directional and must be installed in the proper orientation. 2.3 | Inspect the valve interior through the end ports to determine that it is clean and free from foreign matter and/ or harmful corrosion. Remove any special packing materials (blocks to prevent disc movement) or packages of desiccant. The wedge/discs of weld end gate/globe valves should be lightly closed during welding of the valves into the pipeline. 2.4 | Check the pipeline to ensure that it is properly aligned and supported. Expansion joints or bends should be in stalled in the pipeline to compensate for expansion and contraction. 2.5 | Only qualified riggers should handle the valves. The pick

www.cranecpe.com

up point for all Pacific® valves is by the use of a strap or chain around the neck area of the valve body. Do not pick up Pacific® valves by use of straps or chains on or around the handwheels, yoke, bevel gear, motor or cylinder operator, or any override attachment. Do not pick up a valve by the packing bolting or other interior connections. After the weight of the valve is supported by a strap or chain around the neck of the valve body, other lines may be attached for steadying the valve in place during installation. 2.6 | Immediately prior to valve installation the interior of the piping (to which the valve is to be attached) should be checked for cleanliness and freedom from foreign materials.

3.0 INSTALLATION All valves should be installed in such a manner as to prevent exposure to excessive vibration and process flow turbulence. Check valves specifically are subject to increased turbulence and wear due to their position in a piping system. At a minimum, bolted bonnet check valves should have 10 pipe diameters of straight pipe immediately upstream of the valve and they should not be placed close to pumps, valves or other fittings. When Pacific® valves with bevel gear, motor or air cylinder operators are mounted in a position other than with the valve stem in a vertical position, contact Pacific® for specific instructions. 3.0.1 PREPARATION FOR INSTALLATION INTO THE PIPELINE | Inspect valves as per the above instructions and remove any contamination, assuring that the valve is clean and dry. Re-torque all bolting to factory specifications to compensate for possible bolt relaxation, which may occur during long storage. Ensure that all foreign material has been removed from the valve. 3.1 WELD END VALVES | Welded joints when properly made, provide a structural and metallurgical continuity between the pipe and the valve body. For socket weld joints it is usually required that the weld fillet have more cross sectional area that the pipe. Butt welds usually require full penetration and thickness at least equal to that of the pipe. If a pipe of a high strength alloy is welded to a valve with body material of lower mechanical strength, the weld usually must taper to a compensating greater thickness at the valve end, or the valve must have a matching high strength welded-on extension or "pup".

Valve Installation CAUTION! All welding should be in accordance with any Code or jurisdictional regulations applicable to the piping system construction and with complete and approved welding procedures, and inspected as required by applicable specification. The following items are a general overview of sound welding practice: 3.1.1 | Check material markings on pipe and valve to confirm they are as specified.

tight sealing and compressive deformation of gasket material between facing flange surfaces. The bolting must provide the mechanical force necessary to maintain the necessary compressive stresses on the gasket, as well as resist the normal pressure forces tending to separate the joint. It should be recognized that bolting force used for "brute force" alignment of misaligned flanges will not be available to sustain gasket loading and pressure force loading, and the result may be a joint leakage problem.

3.1.2 | Inspect welding end surfaces, dimensions, and cleanliness. Correct any condition that might interfere with assembly and satisfactory welding.

3.2.1 | Check mating flange facings. If a condition is found which might cause leakage, (e.g. a deep radial groove or cut), do not attempt to assemble until the condition is corrected.

A protective paint may have been applied to the weld ends on some valves, and it should be removed before welding, unless it is a deoxaluminite paint which acts as a welding flux and does not need to be removed.

3.2.2 | Check bolting for proper size, length and material.

3.1.3 | If backing rings are to be used, check to confirm that ring material is compatible with pipe and valve materials, check individual rings for fit and cleanliness. 3.1.4 | Determine that the prescribed welding parameters including preheating and post weld heat treating if required, are in accordance with the approved welding procedure. 3.1.5 INSPECT VALVE-PIPE END ALIGNMENT; ADJUST IF AND AS REQUIRED. | Valves should be in a slightly closed position when welding in-line. This is opposite the normal recommended installation for flanged or threaded valves, which is to leave the valves in a slightly open to fully open position. The reasoning behind slightly closing the valve has to do with the welding installation. When welding valves in-line an electrode is connected to the valve body and the opposite electrode feeds the weld metal across the gap between the valve and the pipeline. If the electrode connected to the valve body is connected on the opposite side of the valve from where the welding is being performed than if the valve is left in an open position the current from the valve electrode to the welding electrode can arc across the gap between the valve disc/wedge and potentially damage or tack weld across the seating surfaces. 3.1.6 | Securely tack weld. 3.1.7 | Complete weld, using approved welding procedure. 3.2 FLANGED VALVES | Pipe flanged joints depend on

32

Crane ChemPharma & Energy

3.2.3 | For flange bolting for steel flanges ASME Class 400 or higher, high strength material (usually B - 7) is required. The proper matching of flanges, bolting and gaskets is important. 3.2.4 | Check gaskets for obvious defects or damage. 3.2.5 | Use care to provide good alignment of flanges being assembled. Use suitable lubricants on bolt threads. When assembling, sequence the bolt tightening (in a star pattern) to make initial contact of flanges and gaskets as flat and parallel as possible. Tighten gradually and uniformly to avoid tendency to twist one flange relative to the other. Use of torque wrench is important to assure correct and uniform final tightening of flange bolting. 3.2.6 | Parallel alignment of flanges is especially important in the case of assembly of a valve into an existing system. It should be recognized that if the flanges are not parallel, in such instances, it would be necessary to bend something to make the flange joint tight. Simply forcing the flanges together with the bolting may bend the pipe, or it may bend the valve. In large diameter piping particularly, such conditions should always be brought to the attention of someone capable of evaluating the bending conditions, and corrective measures taken as needed. 3.2.7 | CAUTION! As indicated above, torque wrenches should be used for flange bolting. If, in the tightening process, the torque on a given bolt has been increasing with each part turn, and then is observed to remain unchanged or increase a much lesser amount with an additional part turn, that bolt is yielding. Such bolt should

www.cranecpe.com


Valve Installation be replaced and scrapped. See Section E for Torque Values. 3.2.8 | Repeat the process at second valve end. Again apply wrench at end of valve to which pipe is being assembled.

4.0 TESTING AND ADJUSTMENT 4.1 | When a valve has been properly inspected and installed, it is reasonable to assume it will be in good condition and ready to operate. Nevertheless, it is at this time that the valve is at the end point of its more vulnerable phase. Operability can be proven only by test. 4.2 | At this point valves having adjustable stem seals should be checked to determine that packing has been properly installed and gland bolting has its initial adjustment. Additional adjustment should be determined according to need as valve operability is checked and as system pressure is introduced. 4.3 | A first observation can be made by actuating the valve through an open-close, or close-open cycle. If no obvious problems are observed, an actual test at pressure may be applied while tightness and operability are checked. 4.4 | It is a fairly common practice after the installation of piping systems to clean the systems by blowing with gas or steam or flushing with a liquid to remove debris and/or internal protective films and coatings. It should be recognized that valve cavities may form a natural trap in a piping system and material not dissolved in or carried out by the flushing fluid may settle in such cavities and adversely affect valve operation. Also, abrasive material carried by a high velocity fluid stream may cause serious damage to seating surfaces. Again, great care should be taken to ensure that the valve is free of all debris prior to operation. 4.5 | Upon installation, new valve lubrication should be applied to all lubrication points.

Packing and Gasket Maintenance and Valve Lubrication 1.0 GENERAL INFORMATION

4.0 GASKET MAINTENANCE

For General Valve Operation & Maintenance Information please refer to Section A of this manual.

NOTE: The following information refers primarily to valves that have been repaired/reconditioned previously. It is always a sound practice to inspect and maintain all sealing areas. Inspection of the valve body/bonnet joint should be a part of routine maintenance inspection after installation and startup. Flanged valves should have the flange ends inspected at the same time. In addition to improper gasket installation procedure, thermal changes, pressure changes, vibrations etc also may cause leakage. If re-torquing of the bolting does not stop the leakage, the flanged joint should be unbolted and the gasket carefully examined.

2.0 PACKING MAINTENANCE 2.1 | Inspection of the valve stem/bonnet seal should be an essential part of routine monthly valve maintenance inspections. 2.2 | If inspection indicates the seal is leaking, the bolts holding the gland flange should be tightened uniformly (one- quarter of a turn at a time) until leakage stops. CAUTION!! Extreme care should be taken when working on or around any pressurized equipment. Tightening of bolting beyond this point results in over- compression of the packing against the stem, thereby producing excessive wear and loss of packing material. If difficulty is experienced in achieving satisfactory sealing without producing excessive stem friction, it may be desirable to increase or to replace the packing material. 2.3 | If gland travel is fully taken up and leakage does not stop, a careful examination of the stem should be undertaken. Operation of a valve on a regular basis will minimize corrosion between the stem and packing material. Any deterioration of the stem surface which is in contact with the stem seal or packing (such as dents, scratches, pitting or general corrosion) must be recognized as a probable cause of leakage problems. The valve stem should be examined to determine if it has become bent or misaligned. If any of the above conditions exist, the stem must be refinished or replaced. If the stem is undamaged and the valve continues to leak, addition to or replacement of the packing is necessary. 2.4 | Consult factory for any further packing related concerns.

Observation

Possible Remedies

Gasket corroded

Select replacement material with improved corrosion resistance.

Gasket extruded excessively

Select replacement material with better cold flow properties, select replacement material with better load carrying capacity - i.e., more dense.

Gasket grossly crushed

Select replacement material with better load carrying capacity, provide means to prevent crushing the gasket by use of a stop ring or redesign of flanges.

Gasket mechanically damaged due to overhang of raised face or flange bore

Review gasket dimensions to insure gaskets are proper size. Make sure certain gaskets are properly centered in joint.

No apparent gasket compression visible

Select softer gasket material. Select thicker gasket material. Reduce gasket area to allow higher unit sealing load. Inspect flange dimensions.

Gasket Substantially on O.D. than I.D.

Indicative of excessive “flange rotation” or bending. Alter gasket thinner dimensions to move gasket reaction closer to bolts to minimize bending movement. Provide stiffness to flange by means of back-up rings. Select softer gasket material to lower required seating stresses. Reduce gasket area to lower seating stresses

Gasket unevenly compressed around circumference.

Improper bolt up procedure followed. Make certain proper sequential bolt up procedures are followed.

Gasket thickness varies periodically

Indicative of “flange bridging” between bolts or warped flanges. Provide reinforcing rings for flanges to better distribute bolt load. Select gasket material with lower seating stress. Provide additional bolts if possible to obtain better load distribution. If flanges are warped, re-machine or use softer gasket material.

3.0 PACKING INSTALLATION & INSTRUCTIONS 3.1 | Manually open and close valve several times to ensure all parts are working smoothly under pressure and to help “set” the packing. 3.2 | After several days, inspect valve for leakage. Slight adjustment may be required. 3.3 | The following suggestions apply if Chevron type Teflon packing is used: 3.3.1 | Ensure that sections of the lips of the rings are not turned over. 3.3.2 | Ensure that the packing rings are facing in the direction of the medium being sealed - whether it is liquid or gas. www.cranecpe.com

Packing and Gasket Maintenance and Valve Lubrication 5.0 GASKET INSTALLATION PROCEDURES Regardless of the type of gasket being used or the materials of construction, certain basic procedures must be followed during assembly to ensure proper operation. While these comments may seem elementary, they are extremely important in achieving a satisfactory seal and minimizing the time required to successfully make up joints. The procedures should be followed whether bolt stresses will be achieved with ordinary stud wrenches, preheating studs, using tensioning devices, using torque wrenches, or using hydraulic wrenches. 5.1 | Inspect the gasket seating surfaces. Look for tool marks, cracks, scratches or pitting by corrosion and make sure that the gasket seating surface is proper for the type of gasket being used. Radial tool marks on a gasket seating surface are virtually impossible to seal regardless of the type gasket being used, therefore every attempt must be made to minimize them. 5.2 | Inspect the gasket. Make sure the material is as specified, look for any possible defects or damage in the gasket. 5.3 | Inspect and clean each stud or bolt, each nut, each washer, and the facing on the flanges against which the nuts will rotate. Look for severe galling, pitting, etc. If any of the above mentioned items are damaged beyond repair, replace the damaged item.

5.7 | Torque the bolts up to a maximum of thirty percent of the final torque value required following the sequence recommended. See Section E for bolting sequence and torques. Number bolts so that torquing requirements can be followed. With any gasket material, it is extremely important to follow a proper bolting sequence. If this sequence is not followed, the flanges can be cocked. Then, regardless of the amount of subsequent torquing, they cannot be brought back parallel. This problem, of course, is maximized on metallic gaskets more so than on non-metallic. 5.8 | Repeat step 5.7, increasing the torque to approximately 50 to 60 percent of the final torque required. 5.9 | Continue with a star pattern of re-torquing all studs or bolts to the desired amount until no further rotation of the nuts can be achieved. This may require several re-torquings since as one stud is torqued it will relieve the stress on the adjacent stud until such time as equilibrium is achieved. 5.10 | On high-pressure, high-temperature applications, it is recommended that the flanges be re-torqued to the required stress after 24 hours at operating pressures and temperatures to compensate for any relaxation or creep that may have occurred.

5.4 | Lubricate all thread contact areas and nut facings. The importance of proper lubrication cannot be over-stressed. No joint should be made up without the proper lubricant being applied to the threaded surfaces and to the nut facings. When flanges will be subjected to high temperatures, the use of an anti-seize compound should be considered to facilitate subsequent disassembly. 5.5 | With raised face and flat face installation, loosely install the stud bolts on the lower half of the flange. Insert the gasket between the flange facing to allow the bolts to center the gasket on the assembly. Install the balance of the bolts and nuts and bring all to a hand-tight or snug condition. 5.6 | If the gasket is being installed in a recess or a groove, center the gasket midway into the recess or the groove. If the joint is vertical it may be necessary to use some cup grease or a few dabs of gasket cement or some other adhesive compatible with the process fluids, to keep the gasket in position until the flanges are tightened.

Proper Fitting of Wedge Gate Valves GENERAL INFORMATION For general information regarding this or any other valve please refer to Section A of this manual.

2.0 INTRODUCTION Fitting of gate valve wedges has a direct effect on the overall performance and longevity of the valve. Occasionally, wear or damage may facilitate the need to refit a gate valve. It is recommended that this operation be entrusted only to an experienced valve mechanic. Although it is recommended that this operation be performed in the shop, with correct equipment and proper care, it can be done with the valve in place. The following are suggested procedures and inspection points:

2.0 PROCEDURE 2.1 | New gate valve wedges are furnished with material left on each side to allow for custom fitting. The amount varies with valve sizes from .025” to .050” per side. Insert the wedge into the body after body seats have been finished and check the following points. 2.1.1 | Adequate finish for fitting. Wedge rides high in body seats. If this is not convenient, use inside calipers to check minimum distance between seats in the body and outside calipers to measure minimum distance across seats of wedge at the toe (bottom). Wedges should be polished/lapped to a minimum of 32 rms. Preferred finish is approximately 12 rms. 2.1.2 | Adequate guide clearance to permit seat face contact. Some valves are designed to allow the wedge to be inserted one way only (wide and narrow guides). Otherwise, select the most advantageous orientation of the wedge in the body. Match mark the body and wedge to ensure proper orientation.

2.1.6 | To check the fit, hang the wedge on a dummy stem (or appropriate fixture), insert it into the body, noting any lean of the wedge relative to the body guides and the guide clearance. Hit the end of the dummy stem with a hammer to seat the wedge and mark the body seat on the wedge. A sharp blow on the bottom of the body will free the wedge from the body seats. To emphasize the position of the seal, a thin film of Prussian Blue can be put on the wedge seat face prior to inserting into the body. 2.1.7 | When the wedge is finally fitted to the body and is resting between the seats (not hammered into place), there should be a small clearance at the toe (bottom), depending on the size and pressure class of the valve (body flexibility). Suggested Toe Clearance

The ideal fit is with the wedge seal uniform and narrow (approx. 1/8”) all around. The seal on the wedge should be below the center of the wedge face (wedge riding high). See Figure 1 below. There should be sufficient guide clearance so that the wedge can seat on both sides. Also, there should be adequate T-head clearance to permit the wedge and stem to be self-aligning.

2.1.3 | Check that the center line of the wedge and body seats are oriented such that the stem T-head has proper clearance to align itself at assembly. 2.1.4 | Mount the wedge in a machine (grinder, boring mill or lathe), on a 10° angle face plate (adjustable or not). Center line of the seat face must be parallel to the guides. 2.1.5 | By trial and error, plus minute adjustments of the wedge angle and the orientation of its center line, fit the wedge to the body seats, by removing small amounts of surface material from the wedge. www.cranecpe.com

Crane ChemPharma & Energy

www.cranecpe.com


Gear and Motor Actuated Valves 1.0 THEORY OF OPERATION

3.0 MAINTENANCE

Most valves, which are located in an accessible environment, are actuated by a manual handwheel mounted directly on top of the valve. When the valve size or differential pressure is so great that the handwheel size cannot keep the operating handwheel pull within customer reasonable limits, then a bevel gear should be mounted on the top-works. In addition, many customers require remote operation or operating times that are not possible with manual handwheels, in this case Electric Motor Actuators (EMO’s) can be used.

The gear or electric actuator itself should never require disassembly and it is recommended that this be done only by the Actuator manufacturer. If it becomes necessary to disassemble the valve, the actuator assembly must be removed first.

NOTE: Actuator limit and torque settings are factory set during valve testing for ASME cold working pressure tests. Additional adjustment may be required in the field. Contact Pacific® with any questions. WARNING! Do not use excessive air wrench torque or snipes on handwheels as the gearing or valve stem could be damaged!

2.0 INSTALLATION

The preferred orientation for Pacific® gear and motor actuated valves is in horizontal pipelines with the stem in a vertical position. When installed in any other position, motor actuated valves should be supported by means of a support clamp around the motor mounting plate. Please contact Pacific® when specifying an actuated valve with an orientation different than that listed above.

3.1 Preventive Maintenance

3.1.1 | With the actuator removed from the valve, examine the stem and actuator drive nut for thread wear, galling or binding. 3.1.2 | If excessive wear is evident, worn parts should be replaced.

Warning! Ensure that the electric motor actuator is wired correctly and phased properly prior to operation. Do not allow the valve to travel in the wrong direction (when phased is reversed). This can result in damage to the valve and void all valve warranties.

Gear and Motor Actuated Valves DISASSEMBLY • Remove operator mounting bolts or stud/nuts 16A and 98A from mounting plate or mounting adapter 120. • Attach a support sling around operator 200 and prevent rotation. • Turn handwheel closed to turn operator off from stem and then lift gear operator off. In the case of an Electric Motor Operator it may be necessary to disengage or “declutch” the motor before using the manual handwheel. The Electric Motor Operator manufacturer’s manual should detail this procedure. • Remove spacer and coupling if used. (Not shown) • NOTE: Prior to the disassembly of any valve equipped with an Electric Motor Operator, ensure that all electrical sources have been disconnected and the appropriate lockout/ tagout procedures have been used. • Proceed with disassembly instructions given in the appropriate valve maintenance instructions.

ASSEMBLY • Install spacer and coupling if used. (Not shown) • Lift gear operator carefully over valve stem and while preventing operator from rotating, turn handwheel open until operator aligns over mounting holes. • Loosely install mounting bolts or stud/nuts 16A and 98A on mounting plate or mounting adapter 120 and then check that stem 70 operation does not bind. • Torque mounting bolts or stud/nuts 16A and 98A while valve is in open position. • Set torque and limit switches in accordance with the instruction manual for the applicable operator. • For all gate and globe style valves upon valve closing, the torque switch should be set to trip first.
