Principle of Operation

HPNS valves are control valves based on the Fisher HP valve product. The valve body and bonnet contain a fluid under pressure, while the internal valve parts control the flow of the fluid through the valve. The internal parts consist of gaskets, a seat ring, a plugstem assembly, and a cage. Additional seals might be used depending on the exact function and design of the valve.

The gaskets, seat ring, and cage are stationary and held in place inside the valve body and bonnet by the force applied by the body-to-bonnet bolting. The plugstem assembly is designed to move up and down (axially) inside the cage. The stem passes through a hole in the bonnet, and can be moved up and down (axially) by an external actuator attached to the valve body, or bonnet. Sealing packing is used between the valve bonnet and plug stem to prevent the fluid from leaking out of the valve, while still allowing the plug stem to move axially.

Fluid enters one end of the valve. When the stem is pushed down, the plug moves to contact the seat ring, and “closes” the valve, preventing the fluid from passing through the valve. When the stem is pulled up, the plug disengages from the seat ring, and slides up through the center of the cage, exposing holes or flow passages in the cage. This allows the fluid to flow through seat ring and cage, and exit the valve through the opposite end of the valve which it entered. By positioning the plug at different "travels" in the cage, the amount of flow through the valve can be controlled.

Lifting Guidelines

WARNING

Failure to follow these lifting guidelines and accepted lifting and rigging practices could result in property damage and personal injury or death.

All lifting and rigging must be completed in accordance with federal/national/provincial, state and local regulations and applicable lifting and rigging equipment standards. Only personnel trained in proper lifting and rigging practices shall perform valve/actuator assembly lifting, rigging and installation. Because each lift will be unique, the method of lifting the valve assembly, the correct location for attaching and lifting the valve assembly, and what the valve assembly will do when lifted shall be considered for each lift.

Lifting and rigging equipment used to lift, install or remove a valve assembly or component must be properly selected and sized for the weight and configuration of the valve assembly or component being lifted. The weight of the complete valve assembly, including attached accessories, must be taken in consideration for this purpose. The lifting and rigging equipment must be properly maintained and inspected for damage before each use.

If the valve is supplied with an actuator or handwheel, do not use the actuator or handwheel to lift the complete valve assembly. Lifting lugs attached to the actuator must not be used to lift the complete valve assembly unless clearly marked as being rated to support the complete valve assembly weight.

Lifting lugs or other lifting equipment attached to the valve or actuator must never be used to lift or support the weight of attached piping.

CAUTION

Care must be taken when lifting the valve/actuator assembly to ensure all accessories and tubing are not damaged in the process. Accessories and tubing may need to be removed prior to lifting to prevent damage and properly reinstalled before use. Protect valve flange faces, butt weld ends, and other connection surfaces from damage during lifting.

The quantity of eyebolts for lifting purpose is the minimum recommendation. More eyebolts can be used per customer experience. When tightening the eyebolts and nuts, do not exceed the torque that is specified on the diaphragm casing cap screws and nuts (keys 119 and 120) in the following sections, to avoid damage on the diaphragm.

Lifting Valve/Actuator Assembly

To lift the valve/actuator assembly, eyebolts should be used. Insert four 3/8 inch shouldered pattern eyebolts positioned 90 degrees apart on the diaphragm casing flange for size 45 and 70. Use six 7/16 inch shouldered pattern eyebolts positioned 60 degrees apart on the diaphragm casing flange for size 80. Two nuts are required with one on each side of the diaphragm casing flange. A longer strap is recommended, so that the angle between the straps connecting each eyebolt can be smaller, which helps the eyebolts hold more weight. The eyebolt should be ASTM A489-K04800 or stronger material.

For a bellows seal valve, the valve/actuator assembly should be lifted using one or more lifting straps that are rigged to choke around the actuator under the diaphragm casing. Use protective pads between the strap(s) and casing to help prevent damage to the painted surface. A single hoist lift point on the strap(s) will balance and lift the valve/actuator assembly in a level manner. If necessary, use additional slings around the valve inlet and outlet or around actuator legs for body stabilization.

Lifting Valve Only

To lift the valve, eyebolts should be used. Insert 3/4-10 inch shouldered pattern eyebolts into two threaded holes located on the top of the NPS 1/2 through NPS 6 valve bodies, positioned 180 degrees apart. For NPS 8 and NPS 10 valve bodies, insert two 3/4-10 shouldered pattern eyebolts into two threaded holes located on the top of the bonnet, positioned 180 degrees apart. The eyebolt material should be ASTM A489-K04800 or stronger material. Be sure at least 90% of the threads are engaged in the receiving hole, with a minimum thread engagement of at least 1-1/2 times the thread diameter in steel. If necessary, place lifting slings around the inlet and outlet of the valve body for stabilization. Use padding as needed to protect any painted surfaces. The valve can now be lifted using a hoist capable of leveling the lifting points.

Instruction Manual

D103466X012

Lifting Actuator Only

To lift the actuator and accessories, eyebolts should be used. Insert two 3/8 inch shouldered pattern eyebolts positioned 180 degrees apart on the diaphragm casing flange for size 45 and 70. Use four 7/16 inch shouldered pattern eyebolts positioned 90 degrees apart on the diaphragm casing flange for size 80. Two nuts are required with one on each side of the diaphragm casing flange. The eyebolt material should be ASTM A489-K04800 or stronger material. For a bellows seal valve, the actuator should be lifted using one or more lifting straps that are rigged to choke around the actuator under the diaphragm casing. Use protective pads between the strap(s) and casing to help prevent damage to the painted surface. A single hoist lift point on the strap(s) will balance and lift the actuator in a level manner.

Installation

When welding buttweld end valves in line, the control valve trim needs to be removed in order to prevent damage to trim parts. The control trim also needs to be replaced with temporary sacrificial trim to be used while conducting the system hydrostatic test and while flushing the system. Flushing the system helps to remove weld slag, rust, corrosion, etc. that could otherwise flow through the valve and potentially damage valve seating surfaces or plug drilled hole trims. The following installation description includes procedures and suggestions to follow for the flushing of the system.

For the NPS 1/2 HPNS with hermetically sealed bellows (DS150), the trim should not be removed during assembly. The position of the plug should be in the “up” position off the seat, with the bellows in the relaxed state. Because the bellows flange is welded directly to the body, it should not be removed until the recommended replacement period, see table 12.

WARNING

Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury.

Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or damage, provide a relief valve for over‐pressure protection as required by government or accepted industry codes and good engineering practices.

Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

WARNING

The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions indicated when the valve was ordered. Responsibility for the safety of process media and compatibility of valve materials with process media rests solely with the purchaser and end‐user. To avoid possible personal injury and because some valve/trim material combinations are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first contacting your Emerson sales office

WARNING

Some bonnet flanges have a tapped hole that was used to handle the bonnet during manufacture. Do not use this tapped hole to lift the valve assembly or personal injury may result.

Instruction Manual

D103466X012

WARNING

If you are hoisting the valve, use lifting slings to protect the surfaces. Carefully position the slings to prevent damage to the actuator tubing and any accessories. Also, take care to prevent people from being injured in case the hoist or rigging slips unexpectedly. Refer to table 2 for valve assembly weights. It is important to use adequately sized hoists and chains or slings when handling the valve.

1. Remove the actuator and disassemble the valve body by completing steps 1 through 10 of the Replacing Conventional Packing section.

2. Before installing the valve, inspect it to ensure that the valve body cavity is free of foreign material.

3. Clean out all pipelines to remove scale, welding slag, and other foreign materials before installing the valve.

Note

If the valve body being installed has small internal flow passages, such as with Whisper Trim III or Cavitrol III cages, consideration should be given to installing an upstream strainer to prevent the lodging of particles in these passages. This is especially important if the pipeline cannot be thoroughly cleaned or if the flowing medium is not clean.

4. Flow through the valve must be in the direction indicated by the flow arrow, which is stamped on or attached to the valve body.

CAUTION

Depending on valve body materials used, post‐weld heat treating might be needed. Post‐weld heat treatment can damage internal elastomeric, plastic, and metal parts. Shrink‐fit pieces and threaded connections might also loosen. In general, if post‐weld heat treating is needed, remove all trim parts. Contact your Emerson sales office for additional information.

5. Install the valve in the line. Use accepted piping and welding practices when installing the valve in the pipeline.

6. Install a three‐valve bypass around the valve if continuous operation is required during maintenance.

7. After installing the valve, inspect it once again to ensure that the valve body cavity is free and clear of foreign material to avoid damaging any internals during flushing.

8. If the actuator and valve body are shipped separately, refer to the actuator mounting procedure in the appropriate actuator instruction manual.

9. If the valve body was shipped without packing installed in the packing box, install the packing

valve body or putting the valve into service

. Refer to instructions given in the Packing Maintenance procedure.

10. For valves that are not being flushed, a replacement soft kit is needed because the trim is removed while the valve is installed. The new soft kit is then used during valve assembly after installation.

11. For valves that will be flushed, some valves are designed such that no damage to internals is expected if the standard valve trim parts are used during flushing. However, it is recommended that that the soft parts (packing and gaskets) be replaced after flushing. Other valves are designed so that the trim can be removed and the valve assembled with a “flushing stem.” Lastly, other valves will require a full flushing trim to be installed instead of the standard trim. Valves using trim with hard-facing and valves using trim with small drilled holes or a small flow path where particulate up to 1/4 inch can become lodged will require flushing trim. Table 7 details which special trim parts are needed based on flow direction.

(1)

Soft Parts, Flushing System, Flushing Nuts, Flushing Cage and Flushing Seat Ring

a. After installing the bonnet gasket, tighten 2 of the 4 flushing nuts to the base of the flushing stem. When

installing the nuts, ensure that the flat side of the upper nut (the side closest to the bonnet) is facing the bonnet and that any of the grade markings are facing away from potentially contacting the bonnet.

b. Insert the flushing stem up through the bonnet (key 10), being careful not to scratch or otherwise damage the

stem.

c. Install new packing and the metal packing box parts according to steps 19 and 20 of the Replacing Conventional

Packing Section. If working on a valve with HIGHSEAL Packing, follow steps 2 through 7 of the HighSeal packing installation section. At this point, do not tighten the packing bolts down.

d. Tighten the other two leftover flushing nuts to the top of the stem to secure the stem in position with the

bonnet.

e. Following step 17 of the Replacing Conventional Packing Section, place the bonnet on to the studs (key 7),

taking care to ensure that while moving the bonnet the flushing stem does not slide around and become damaged.

f. Follow step 18 of the Replacing Conventional Packing Section to torque the bonnet into place. Because the stem

is not connected to the rest of the trim, the note about stroking the valve to center the trim can be omitted.

g. Now torque the packing bolts per table 6 if using conventional packing or step 8 of the HIGHSEAL Packing

Installation Section.

h. For those datasheets that require a full flushing trim, follow step 16 of the Replacing Conventional Packing

section up to the installation of the bonnet gasket (key 6), ensuring that the standard seat ring and standard cage are replaced with the appropriate flushing cage and flushing seat ring. Then, follow the assembly directions shown above for the installation of the flushing stem and nuts.

12. After system flushing is completed, remove the bonnet (key 10), bonnet gasket (key 6), and, if necessary, flushing trim and seat ring gasket (key 5).

13. Assemble the valve as described in the Replacing Conventional Packing procedure, steps 11 through 20.

14. Refer to the actuator mounting procedure in the appropriate actuator instruction manual.

WARNING

Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing might require some readjustment to meet specific service conditions. Please read and follow the packing adjustment procedures in the Packing Maintenance section of this manual.

Valves with HIGH‐SEAL Heavy‐Duty live‐loaded packing will not require this initial re‐adjustment. See the Replacing HIGH‐SEAL Packing section in this manual for packing instructions.

Maintenance

Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance frequency depends on the severity of service conditions. This section includes instructions for packing maintenance and trim maintenance. All maintenance operations may be performed with the valve in the line.

Instruction Manual

D103466X012

WARNING

Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before starting disassembly:

D Do not remove the actuator from the valve while the valve is still pressurized.

D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

on both sides of the valve. Drain the process media from both sides of the valve.

D Vent the power actuator loading pressure and relieve any actuator spring precompression.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

Note

The HPNS valve uses spiral‐wound gaskets which are crushed to provide their seal. A spiral‐wound gasket should never be reused. Whenever a gasket seal is disturbed by removing or shifting gasketed parts, a new gasket must be installed upon reassembly. This is necessary to ensure a good gasket seal, since the used gasket will not seal properly.

CAUTION

The spiral‐wound gaskets are of special design. Failure to use Fisher replacement parts may result in valve damage.

Note

If the valve has HIGH‐SEAL Heavy‐Duty live‐loaded packing installed (figure 4 or 5), see the Replacing HIGH‐SEAL Packing section in this manual for packing instructions.

Bonnet Nut Torquing Considerations

When using a hydraulic torque wrench to tighten the bonnet nuts, use an extra socket or some other form of tooling to prevent the reaction arm from contacting the adjacent bonnet nut. This will help prevent damage to the bonnet nut faces. See figure 2 for a diagram of this procedure.

Packing Lubrication

Note

No provisions for packing lubrication.

WARNING

Do not lubricate any parts or surfaces that may come into contact with the process media. Any use of lubricant can lead to the contamination of the process media and could lead to property damage or failure.

Packing Maintenance

If there is undesirable packing leakage in conventional packing, first try to limit the leakage and establish a stem seal by tightening the packing flange nuts (key 14, figure 20, 22, 23, or 24) to at least the minimum recommended torque in table 6. However, do not exceed the maximum recommended torque in table 6 or excessive friction may result. If leakage continues, replace the packing by following the numbered steps presented in the Replacing Conventional Packing procedure.

If the packing is relatively new and tight on the valve plug stem, and if tightening the packing flange nuts does not stop the leakage, it is possible that the stem is worn or nicked so that a seal cannot be made. The surface finish of a new stem is critical for making a good packing seal. If the leakage comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches around the packing box wall. While replacing the packing according to the Replacing Packing procedure, inspect the valve plug stem and packing box wall for nicks or scratches.

If there is undesirable packing leakage in HIGH-SEAL packing, first try to limit the leakage and establish a stem seal by tightening the packing flange nuts (key 14, figure 20, 22, 23, or 24) to at least the minimum spring load shown in

figure 9. However, do not exceed the maximum spring load shown in figure 9 or excessive friction may result. If leakage continues, replace the packing by following the numbered steps presented in the Replacing HIGH-SEAL Packing procedure.

Replacing Conventional Packing

WARNING

Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

Key numbers referred to in this procedure are shown in figure 20, 22, 23, or 24, unless otherwise indicated.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the process media from both sides of the valve. If using a power actuator, also shut‐off all pressure lines to the power actuator, release all pressure from the actuator. Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

2. Exhaust all actuator pressure, if any was applied, and disconnect the actuator supply and any leakoff piping.

3. Using the appropriate actuator instruction manual for reference, relieve all spring compression from the actuator.

4. Remove the cap screws in the stem connector, and separate the two halves of the stem connector.

5. Remove the hex nuts, and remove the actuator from the body (key 1) or bonnet (key 10). If additional actuator removal clearance is required for disassembly, loosen, then remove the packing flange nuts (key 14) per step 6. Then lift the packing flange (key 9) to allow the actuator to pass underneath. Return the packing flange (key 19) and packing flange nuts (key 14) to the packing flange studs (key 15). Thread the packing flange nuts (key 14) to the packing flange studs (key 15) to realign with step 6.

6. Loosen the packing flange nuts (key 14) so that the packing (figure 3) is not tight on the valve plug stem (key 4). Remove any stem locknuts from the valve plug stem threads.

CAUTION

Avoid damage to the seating surfaces caused by the valve plug and stem assembly (key 4) dropping from the bonnet (key

10) after being lifted part way out. When lifting the bonnet (key 10), either be sure that the valve plug and stem assembly (key 4) remain in the valve and on the seat ring (key 3) or, temporarily install a valve stem locknut on the valve stem. This locknut will prevent the valve plug and stem assembly from dropping out of the bonnet.

Use care to avoid damaging gasket sealing surfaces.

The HPNS balanced trim piston rings (key 23) are brittle and in two pieces. Avoid damaging the piston rings by dropping or rough handling.

Note

The following step also provides additional assurance that the valve body fluid pressure has been relieved.

7. Hex nuts (key 8) and washers (key 24) attach the bonnet to the valve body. Loosen these nuts approximately 3 mm (1/8 inch). Then loosen the body‐to‐bonnet gasketed joint by either rocking the bonnet or prying between the bonnet and valve body. Work the prying tool around the bonnet until the bonnet loosens. If no fluid leaks from the joint, proceed to step 9

8. If leakage does occur from the joint, tighten the nuts and verify that the process is properly shut down or the valve is properly bypassed.

9. Unscrew the hex nuts (key 8), remove the washers (key 24) and carefully lift the bonnet off the valve stem.

Note

The cage and cage retainer lifting holes are provided for ease of assembly/disassembly. To prevent damage to the lifting holes, fully engage the threaded rod into the hole, but do not overtighten the hoist rod. It only needs to be hand tight. If it is hard to lift the cage or cage retainer, a piece of wood and a hammer can be used to strike on the top chamfer of the cage or cage retainer to loosen it from cage, body, or seat ring gasket. ASTM A193 B7 or comparable threaded rods are required for cage or cage retainer removal. Contact your Emerson sales office

for more information.

CAUTION

Inspect the seat ring, cage, cage retainer (if applicable), bonnet, and body gasket surfaces. These surfaces must be in good condition, with all foreign material removed. Small burrs less than approximately 0.076 mm (0.003 inches) in height (the thickness of a human hair) can be ignored. Scratches or burrs that run across the serrations are not permitted under any conditions, since they will prevent the gaskets from sealing properly.

11. Clean all gasket seating surfaces; refer to your process or safety engineer for appropriate cleaning tools. Clean in the same direction as the surface serrations, not across them.

12. Cover the opening in the valve body to protect the gasket seating surface and to prevent foreign material from getting into the valve body cavity.

13. Remove the packing flange nuts (key 14), packing flange (key 9), and packing follower (key 17). Carefully push out all the remaining packing parts from the valve side of the bonnet using a rounded rod or other tool that will not scratch the packing box wall.

14. Clean the packing box and the following metal packing parts: packing follower, packing box ring (key 11).

15. Inspect the valve stem threads and packing box surfaces for any sharp edges that might cut the packing. Scratches or burrs could cause packing box leakage or damage to the new packing. If the surface condition cannot be improved by light sanding or honing with a tool similar to a small honing stone, replace the damaged parts.

16. Remove the protective covering from the valve body cavity, and install the seat ring, cage, and cage retainer (if applicable) using a new seat ring gasket (key 5), bonnet gasket (key 6), and cage gaskets (key 36) (if applicable). Install the plug, then slide the bonnet over the stem and onto the studs (key 7).

17. If required, place a body/bonnet mounting washer (key 24) over each stud, taking care to ensure that the washers are pushed as far as possible toward the center of the bonnet. Failure to do so could prevent successful actuator mounting. Before installing the washers, inspect each one to ensure no wear or galling is present on the washer faces. Replace if wear is detected. Also, lubricant is not required on the washers. All required lubricant will be applied when the nuts are installed.

Note

The proper bolting procedures in step 18 include‐‐but are not limited to‐‐ensuring that the bonnet stud threads are clean, and that the hex nuts are evenly tightened to the specified torque values.

WARNING

Personal injury or damage to equipment could occur if improper stud and nut materials or parts are used. Do not operate or assemble this product with stud(s) and nut(s) that are not approved by Emerson/Fisher engineering and/or listed on the serial card provided with this product. Use of unapproved materials and parts could lead to stresses exceeding the design or code limits intended for this particular service.

18. Lubricate the stud threads (key 7) and the seating faces of the hex nuts (key 8) with Nuclear Grade anti-seize lubricant (key 27). Replace the hex nuts and tighten them finger‐tight. Stroke the valve several times to center the trim. Torque the nuts in a crisscross pattern (reference figure 8) to no more than 1/4 of the nominal torque value specified in table 5.

Note

If using a hydraulic torque wrench, please see the Bonnet Nut Torquing Considerations section on page 9 to avoid any unsatisfactory marring of parts.

When all nuts are tightened to that torque value, increase the torque by 1/4 of the specified nominal torque and repeat the crisscross pattern. Repeat this procedure until all nuts are tightened to the specified nominal value. Apply the final torque value again and, if any nut still turns, tighten every nut again.

Note

When installing packing rings, prevent entrapping air between the rings. Add the rings one at a time without forcing them below the chamfer of the packing box entrance chamber. As each successive ring is added, the stack should not be pushed down more than the thickness of the added ring (figure 6).

19. Install new packing and the metal packing box parts according to the arrangement in figure 3, 4, or 5. Place a smooth-edged pipe over the valve stem, the top end higher than the valve stem is recommended. An alternative way is to slide the packing follower over the valve stem. Gently tamp each soft packing part into the packing box, being sure that air is not trapped between adjacent soft parts.

20. Slide the packing follower and packing flange into position. Lubricate the packing flange studs (key 15) and the seating faces of the packing flange nuts (key 14) with Nuclear Grade anti-seize lubricant (key 27). Replace the packing flange nuts.

Torque evenly in increments of 1/4 of the full torque value, alternating between the packing flange nuts. Tighten the packing flange nuts to the maximum recommended torque shown in table 6. Then, loosen the packing flange nuts, and retighten them to the recommended minimum torque shown in table 6.

7. The load scale (key 22) is used to indicate compression on the Belleville springs. Position the load scale by slightly loosening the mounting screws (key 21). Align the bottom edge of the load scale with the indicator disk and retighten the screws. Figure 9 illustrates the load scale properly adjusted before the nuts have been tightened and with the Belleville springs not compressed.

8. Tighten the packing nuts while observing the two load scales (key 22) to make sure the flange (key 9) is tightened evenly. Be sure to keep the follower centered on the stem while tightening the nuts. Tighten the nuts alternately and evenly, keeping the flange parallel with the valve, until the indicator disk aligns with the maximum compression line on the load scales.

9. The packing is now properly loaded and the packing nuts do not need to be retightened unless the indicator begins to approach the minimum compression line. After the valve has been in service for awhile, visually check the load scale to determine loading. Under normal conditions, the packing nuts should not require retightening for the life of the packing.

Trim Removal

Standard Balanced and Unbalanced Trim Removal

Key numbers referenced in this procedure are shown in figure 20, 22, 23, or 24 except where indicated.

1. Remove the actuator and bonnet by following steps 1 through 9 of the replacing packing procedure. Observe all warnings and cautions.

CAUTION

Use care to avoid damaging gasket surfaces. The surface finish of the valve stem (key 4) is critical for making a good packing seal. The inside surface of the cage or cage

assembly (key 2) is critical for smooth operation of the valve plug and for making a seal with the piston rings (key 23) or seal rings (key 31). The seating surfaces of the valve plug (key 4) and seat ring (key 3) are critical for proper shutoff. Assume all these parts are in good condition, and protect them accordingly unless inspection reveals otherwise.

2. Lift the valve plug/stem assembly out of the valve body. If the valve plug/stem assembly is to be reused, tape or otherwise protect the valve plug stem and the valve plug seating surface to prevent scratches.

3. To remove the piston rings and bidirectional PEEK antiextrusion seal rings for a balanced HPNS construction, proceed as appropriate:

For pistonrings constructions, each of the piston rings (key 23) are in two pieces; locate the break between sections of the piston rings. Using an appropriate tool such as a flatblade screwdriver, carefully pry out the piston rings from the grooves in the plug.

For bidirectional PEEK antiextrusion seal rings constructions, use an appropriate tool and carefully remove the retainer ring (key33) from the valve plug. Then remove the remaining qty1 backup ring (key 29), qty2 antiextrusion rings (key 30), qty2 spring loaded seal rings (key 31), and qty1 spacer ring (key 32) from top of the plug (figure 11).

4. Lift out the bonnet gasket (key 6), the cage retainer (key 37) and cage gaskets (key 36) (if applicable), and the cage (key 2). See step 10 of the Packing Removal section for more instructions on using threaded rods to assist in removing the cage and cage retainer if necessary.

5. Remove the seat ring (key 3) and the seat ring gasket (key 5).

2. Remove the plug/retainer assembly (with Bore Seal plug seal), cage retainer (if applicable), cage, and seat ring from the valve body following the appropriate instructions in the Trim Removal section in this manual.

3. Locate the staked thread on top of the valve plug (figure 15). The staked thread secures the retainer. Use a drill with a 1/8 inch bit to drill out the staked area of the thread. Drill approximately 1/8‐inch into the metal to remove the staking.

4. Locate the break between sections of the piston ring(s). Using an appropriate tool such as a flat‐blade screwdriver, carefully pry out the piston ring(s) from the groove(s) in the Bore Seal retainer.

5. After removing the piston ring(s), locate the 1/4‐inch diameter hole in the groove. In a retainer with more than one piston ring grooves, the hole may be found in the upper or lower groove.

6. Select an appropriate tool such as a strap wrench and rotate the retainer and free it from the valve plug. Remove the retainer from the plug.

7. Use an appropriate tool such as a flat‐blade screwdriver to pry the Bore Seal plug seal off the plug. Use caution to avoid scratches or other damage to the sealing surfaces where the Bore Seal plug seal makes contact with the valve plug (figure 10).

8. Inspect the lower seating surface where the valve plug contacts the seat ring for wear or damage which would prevent proper operation of the valve. Also, inspect the upper seating surface inside the cage where the Bore Seal plug seal contacts the cage, and inspect the sealing surface where the Bore Seal plug seal makes contact with the plug (figure 10).

WARNING

Observe the warning at the start of the Maintenance section.

After all trim maintenance has been completed, reassemble the valve body by following the numbered steps below. Be certain that all gasketed surfaces have been well cleaned. Key numbers referenced in this procedure are shown in figure 20, 22, or 23, except where indicated.

HPNS Valve

March 2022

Instruction Manual

D103466X012

CAUTION

Inspect the seat ring, cage, bonnet, and body gasket surfaces. These surfaces must be in good condition, with all foreign material removed. Small burrs less than approximately 0.076 mm (0.003 inches) in height (the thickness of a human hair) can be ignored. Scratches or burrs that run across the serrations are not permitted under any conditions, because they will prevent the gaskets from sealing properly.

The pressure balancing holes in the valve plug are necessary for the proper and safe operation of the valve. Inspect the balancing holes every time the valve is disassembled for service. Any build-up, blockage, or clogging of the balance holes should be removed.

1. Install the seat ring gasket (key 5) into the valve body (key 1). Install the seat ring (key 3).

2. Install the cage (key 2).

3. To install the piston rings, bidirectional PEEK antiextrusion seal rings, and bore seal (key 26) for a balanced HPNS construction, proceed as appropriate:

For piston rings constructions, if it is necessary to install new piston rings, the replacement piston rings will arrive in one piece. Use a vise with smooth or taped jaws to break a replacement piston ring into halves. Place the new ring in the vise so that the jaws compress the ring into an oval. Compress the ring slowly until the ring snaps on both sides. If one side snaps first, do not try to tear or cut the other side. Instead, keep compressing until the other side snaps. The piston ring can also be fractured by scoring and snapping over a hard surface such as a table edge. Sawing or cutting is not recommended.

Remove any protective tape or covering from the valve plug and stem assembly, and set it on a protective surface. Then, place the piston rings in the piston ring grooves with the fractured ends matched.

CAUTION

For valves with a PTFE seal ring (figure 11), if replacing the valve plug spring loaded seal ring (key 31), be careful not to scratch the surfaces of the ring groove in the valve plug or any of the surfaces of the replacement ring, or the replacement ring may not seal properly.

For bidirectional PEEK antiextrusion seal rings constructions, install qty1 antiextrusion ring (key 30), qty1 spring loaded seal ring (key 31), qty1 spacer ring (key 32), qty1 spring loaded seal ring (key 31), qty1 antiextrusion ring (key 30), and qty1 backup ring (key 29) onto the top of the plug with the orientation shown in figure 11. Install the retainer ring (33) into the groove on top of the plug.

Note

To install the spring loaded seal ring (key 31), gently stretch the seal ring and work it over the top edge of the valve plug. Give the PTFE material in the seal ring time to cold flow during the stretching procedure. Avoid jerking sharply on the ring. Stretching the seal ring over the valve plug might make it seem loose when it is in the groove, but it will shrink to its original size after you have installed the plug into the cage.

For bore seal constructions, install the bore seal (key 26, figure 12) onto the valve plug (key 4) following the Installing Bore Seal Trim section in this instruction manual.

4. If applicable, install the cage gaskets (key 36) and cage retainer (key 37).

5. Install the valve plug into the cage.

Installing Dynamic Bore Seal Trim

1. Orient the Bore Seal for correct sealing action based on the process fluid flow direction through the valve, as shown in figure 12.

D The open interior of the Bore Seal must face up in a valve with flowup construction.

D The open interior of the Bore Seal must face down in a valve with flowdown construction.

2. Place the Bore Seal plug seal over the top of the valve plug. The retainer will help guide the Bore Seal down onto the plug. Do not force the Bore Seal over the plug (figure 14). For flow down constructions, skip to step 4.

3. For flow up constructions, an installation tool must be inserted into the Bore Seal prior to using the retainer to guide it down the plug. Refer to figure 13 for dimensions and part number for ordering the installation tool.

4. Place the Bore Seal retainer onto the plug and tighten the retainer using an appropriate tool such as a strap wrench. For flow down constructions, skip to step 6.

5. Remove the retainer and then the installation tool. Place the Bore Seal retainer back onto the plug and tighten the retainer using an appropriate tool such as a strap wrench. Visually inspect the retainer to ensure it is fully seated on the valve plug.

6. Using an appropriate tool such as a center punch, stake the threads on top of the plug in one place to secure the Bore Seal retainer.

CAUTION

To avoid leakage when the valve is returned to service, use appropriate methods and materials to protect all sealing surfaces of the new trim parts while assembling the individual parts and during installation in the valve body.

7. Install piston rings by following instructions in the Trim Replacement section in this manual.

CAUTION

To avoid excessive leakage and seat erosion, the valve plug must be initially seated with sufficient force to overcome the resistance of the Bore Seal plug seal and contact the seat ring. You can correctly seat the valve plug by using the same force calculated for full load when sizing your actuator. With no pressure drop through the valve, this force will adequately drive the valve plug to the seat ring, thus giving the Bore Seal plug seal a predetermined permanent set. Once this is done, the plug/retainer assembly, the cage, and the seat ring become a matched set.

With full actuator force applied and the valve plug fully seated, align the actuator travel indicator scale with the lower end of valve travel. Refer to the appropriate actuator instruction manual for information on this procedure.

8. Replace trim parts if any damage to sealing surfaces has occurred.

Installing Static Bore Seal Trim

1. Orient the Bore Seal for correct sealing action based on the process fluid flow direction through the valve, as shown in figure 12.

D The open interior of the Bore Seal must face up in a valve with flowup construction.

D The open interior of the Bore Seal must face down in a valve with flowdown construction.

2. Place the bore seal ring onto the lowest groove of the cage. Note that seal installation should be done prior to installing the cage into the valve. Unless lubrication is not allowed to be in contact with the process media, apply a suitable high-temperature lubricant to the outside diameter of the bore seal. Also lubricate the inside of the cage where the bore seal must be pressed into the proper sealing position. Orient the bore seal for the correct sealing action based on whether the valve is flow up or flow down. The open interior of the bore seal must face up in a valve with flow-up construction and face down in a valve with flow-down construction. Place the bore seal at the top of the seal groove in the cage. The seal will not fit completely into the groove with hand force alone. Trying to force the seal in may damage the seal.

3. An installation tool must be used as shown in figure 17 to help press the seal ring evenly onto the cage and make sure the seal ring is centered until the installation tool and cage contact metal-to-metal. See figure 16 and table 9 for tool dimensions and part numbers.

4. Remove the installation tool and place the backup ring into the seal groove until it touches the seal ring.

5. The cage can then be installed into the valve body by following the steps in the Trim Replacement section in this manual.

Packing Maintenance

If there is undesirable packing leakage in HIGH-SEAL packing, replace the packing and bellows seal at same time by following the numbered steps presented in Replacement of an Installed Bellows Seal procedure.

Note

It is recommended the replacement of packing and bellows seal is always completed at same time.

Replacement of an Installed Bellows Seal

Key numbers referred to in this procedure are shown in figure 21, unless otherwise indicated.

Refer to the WARNINGS at the beginning of the Maintenance section in this instruction manual.

1. Remove the actuator and yoke spacer from the body (key 1) following step 1 through 6 of Replacing Conventional Packing section.

CAUTION

Use care to avoid damaging gasket sealing surfaces on bonnet, bellows flange and body.

WARNING

To avoid personal injury or property damage caused by uncontrolled movement of the bonnet and bellows flange, loosen the bonnet by following the instructions in the next step. Do not remove a stuck bonnet or bellows flange by pulling on it with equipment that can stretch or store energy in any other manner. The sudden released of stored energy can cause uncontrolled movement of the bonnet and bellows flange. If the cage sticks to the bellows flange, proceed carefully with bellows flange removal and support the cage so that it will not fall unexpectedly from the bellows flange.

Note

The following step also provides additional assurance that the valve body fluid pressure has been relieved.

2. Purge the line of any combustible process fluid.

WARNING

To avoid personal injury or property damage during removal of the bellows flange weld, combustible fluids must be purged from the valve and bellows prior to removal of the flange weld.

3. Hex nuts (key 8) attach the bonnet to the valve body. Loosen these nuts approximately 3 mm (1/8 inch). Carefully remove the welding around the bellows flange with appropriate tools. If no fluid leaks from the joint, proceed to step 5.

Note

Use care to avoid damaging body top surface when removing the seal-weld between body and bellows flange.

4. If leakage does occur from the joint, tighten the nuts and verify that the process is properly shut down or the valve is properly bypassed.

5. Unscrew the hex nuts (key 8) and carefully lift the bonnet off the valve stem. If the valve stem starts to lift with the bonnet, use a hammer on the end of the stem and tap it back down. Set the bonnet on a cardboard or wooden surface to prevent damage to the bonnet gasket surface.

6. Remove the bonnet gasket (key 6). Lift the bellows/stem assembly (key 35) out of the valve body and set it on a protective surface. Carefully lift the cage (key 2) and then seat ring (key 3) out of the valve body. Remove the seat ring gasket (key 5).

CAUTION

Inspect the seat ring and body (seat web) gasket surfaces. These surfaces must be in good condition, with all foreign material removed. Small burrs less than approximately 0.076 mm (0.003 inches) in height (the thickness of a human hair) can be ignored. Scratches or burrs that run across the serrations are not permitted under any conditions, since they will prevent the gaskets from sealing properly.

7. Clean all gasket seating surfaces; refer to your process or safety engineer for appropriate cleaning tools. Clean in the same direction as the surface serrations, not across them.

8. Cover the opening in the valve body to prevent foreign material from getting into the valve body cavity.

9. Remove the packing flange nuts (key 14), packing flange (key 9), indicator disk (key 19), qty-2 Belleville springs (key 20), qty-4 load scale mounting screws (key 21), qty-2 load scales (key 2) and packing follower (key 17). Carefully push out all the remaining packing parts from the valve side of the bonnet using a rounded rod or other tool that will not scratch the packing box wall.

10. Clean the packing box and the following metal packing parts: packing follower (key 17), packing box ring (key 11).

11. Inspect the valve stem threads and packing box surfaces for any sharp edges that might cut the packing. Scratches or burrs could cause packing box leakage or damage to the new packing. If the surface condition cannot be improved by light sanding or honing with a tool similar to a small honing stone, replace the damaged parts.

12. Remove the protective covering from the valve body cavity, and install the seat ring and cage using a new seat ring gasket (key 5).

13. Install new bellows/stem assembly (key 35) into the bore of the cage (key 3).

14. Coat qty-4 fixture studs with Nuclear Grade anti-seize lubricant (key 27) up to the deformed thread. Thread the studs into yoke mounted threaded holes in the valve body (key 1) by hand until the deformed thread prevents further insertion.

15. Slide loading fixture over the studs and bellows/stem assembly (key 35) shown in figure 18, make sure the bottom of the fixture is flush with the mating surface on the bellows flange.

16. Turn the nuts onto the studs until hand tight. Tighten the fixture nuts to the torque value of 250 ft-lb (339 N-m). Tighten each bolt evenly in at least 4 torque steps and follow the criss-cross bolting pattern. Dividing the torque

procedure into even more equally spaced torque increments will ensure that the bellows flange is not unevenly loaded during assembly.

Note

Make sure metal to metal contact can be seen between valve body (key 1) and the bellows flange. Feeler gage needs to be used to make sure the metal contact was obtained.

17. Check if the stem is centered in the bellows tube connector (on top of the bellows assembly). If not, loosen the weld fixture slightly and then adjust the bellows flange to ensure the concentricity of the bellows tube connector and stem. This task may be accomplished with assistance of a wire gage or visual inspection and a dead blow hammer applied to the bellows flange to tap the assembly into place gently without damaging the parts.

18. Fillet-weld the bellows flange to the valve body (key 1) using GTAW weld process specified in weld procedure FMP 5CP8.8G1.1TSNN. The weld size shall be in range of 0.20 inch to 0.29 inch. The weld contour shall be flat.

Note

Do not damage or deform threaded bolt holes in valve body while performing seal-weld.

CAUTION

The weld needs to be fully cooled before fixture removal. Do not quench, but let metal cool naturally.

19. Remove the bolts, nuts and loading fixture.

WARNING

Pressurizing the valve before the bonnet is installed, can cause death, personal injury and/or property damage. Seal weld will NOT resist valve pressure without bonnet and bonnet-to-body bolting.

20. Perform liquid penetrant examination of the weld joint and clean per applicable procedures.

21. Install a new bellows flange-to-bonnet spiral wound gasket (key 6) into the gasket groove on top of the bellows flange.

22. Coat the bonnet studs (key 7) with Nuclear Grade anti-seize lubricant (key 27) up to the deformed thread. Thread the studs into the valve body (key 1) by hand until the deformed thread prevents further insertion.

23. Install the bonnet (key 10) over the bonnet studs and onto bellows flange. The bonnet should be standing up as straight as possible, and gently slide into the bellows assembly with care. Make sure that the “Fisher” logo on the bonnet is on the same side as the “Fisher” logo on the body. When installing the bonnet, take care to ensure that it sits flush against the spiral wound gasket (key 6) between the bellows flange and the bonnet.

24. Lubricate the remaining bonnet studs (key 7) with Nuclear Grade anti-seize lubricant (key 27).

Instruction Manual

D103466X012

25. Perform bonnet to body bolts installation following step 17 through 18 of Replacing Conventional Packing section, including all the cautions, notes and warnings.

Note

26. Install new packing and the metal packing box parts according to the arrangement in figure 4. Place a smooth-edged pipe over the valve stem, the top end higher than the valve stem is recommended. An alternative way is to slide the packing follower over the valve stem. Gently tamp each soft packing part into the packing box, being sure that air is not trapped between adjacent soft parts.

27. Continue the packing installation following step 3 through 9 of Replacing HIGH-SEAL Packing section.

28. Mount the actuator by following the procedures in the actuator instruction manual.
