Tightening ProcedureTo obtain the target load of 85% compression ofmaximum deflection, perform the following:

� Tighten the packing flange nuts alternately andevenly, keeping the packing flange parallel with thevalve flange, until the Belleville springs arecompressed 100% (or completely flat), as detectedby a rapid increase in nut torque. Refer to theinstruction manual for ENVIRO-SEAL packingsystems for sliding stem valves if you need furtherassistance.

� For graphite ULF packing, loosen each packingflange nut 1/4 turn (90 degrees rotation).

The ‘‘target load’’ of 85% compression has nowbeen reached.

1. The “springs flat” procedure described above isthe preferred method of adjusting ENVIRO-SEALGraphite ULF packing. However, the torque valuesin table 1 can also be used as a guideline for 85%spring compression. These values are based ongenerous lubrication of the packing studs and nutswith Never-Seez lubricant. Loosening of the packingflange nuts is not required when these torques areused.

2. Refer to the appropriate valve and actuatorinstruction manuals when connecting the valve tothe actuator. Under normal conditions, the packingnuts should not require re-tightening.

Additional Specifications

For specifications such as materials, valve plugtravels, and port, yoke boss, and stem diameters,see the Parts List section

1. The pressure or temperature limits in this manual and any applicable standard limitations should not be exceeded.2. Modified equal percentage characteristic is equal-percentage for the first 90% of travel, then quick-opening for additional capacity.

The Design EHS valve uses an unbalanced valveplug. To provide a seal between the cage and abalanced valve plug, the Design EHD valve pluguses piston rings; the Design EHT valve plug uses apressure-assisted seal ring. A Whisper Trim cagecan be used with a Design EHD, EHS, or EHT valveplug. A Cavitrol III cage can be used with a DesignEHS or EHT valve plug.

C-seal trim is available for Design EHD valves, class2500, in sizes 4, 6, 6x4, and 8x6.

With C-seal trim, a balanced valve can achievehigh-temperature, Class V shutoff. Because theC-seal plug seal is formed from metal (N07718nickel alloy, Inconel 718) rather than an elastomer,avalve equipped with the C-seal trim can be appliedin processes with a fluid temperature of up to 593�C(1100�F), provided other material limits are notexceeded.

Installation

WARNING

Always wear protective gloves,clothing, and eyewear whenperforming any installation operationsto avoid personal injury.

To avoid personal injury or propertydamage resulting from the suddenrelease of pressure, do not install thevalve assembly where serviceconditions could exceed the limitsgiven in this manual or on theappropriate nameplates. Usepressure-relieving devices as requiredby government or accepted industrycodes and good engineering practices.

CAUTION

The valve configuration andconstruction materials were selectedto meet particular pressure,temperature, pressure drop, andcontrolled fluid conditions specified inthe customer’s order. Because somebody/trim material combinations arelimited in their pressure drop andtemperature range capabilities(especially due to differences inthermal expansion rates), do not applyany other conditions to the valvewithout first contacting your Fishersales office.


Form 5163March 2002

CAUTION

If hoisting the valve, use a nylon slingto protect the painted surfaces.Carefully position the sling to preventdamage to the tubing or anyaccessories. Also, take precautions toprevent personnel from being injuredin case the hoist or rigging slipsunexpectedly. Refer to table 6 for valveassembly weights. Using adequatelysized hoists and chains or slings tohandle the valve is important.

1. Before installing the valve, inspect it to ensurethat the valve body cavity is free of foreign material.

2. Clean out all pipelines to remove scale, weldingslag, and other foreign materials before installing thevalve.

Note

If the valve being installed has smallinternal flow passages, such as withWhisper Trim III or Cavitrol III cages,consideration should be given toinstalling an upstream strainer toprevent the lodging of particles inthese passages. This is especiallyimportant if the pipeline cannot bethoroughly cleaned or if the flowingmedium is not clean.

3. The control valve must be installed with theactuator vertical above the valve body for properoperation. Flow through the valve must be in thedirection indicated by the flow arrow (key 15, figure17, 18, or 19) on the valve body.

4. Use accepted piping and welding practices wheninstalling the valve in the line. For welding end valvebodies, completely disassemble the valve removingall trim parts before welding the valve body in theline. For flanged valve bodies, use suitable gasketsbetween the valve body flanges and pipelineflanges.

Note

Depending on valve body materialsused, post-weld heat treating might beneeded. Post-weld heat treatment candamage internal elastomeric, plastic,and metal parts. Shrunk-fit pieces andthreaded connections might loosen. Ingeneral, if post-weld heat treating is

needed, remove all trim parts. Contactyour Fisher sales office for additionalinformation.

5. Install a three-valve bypass around the valve ifcontinuous operation is required duringmaintenance.

6. If the actuator and valve body are shippedseparately, refer to the actuator mounting procedurein the appropriate actuator instruction manual.

WARNING

Personal injury could result frompacking leakage. Valve packing wastightened prior to shipment; howeversome readjustment will be required tomeet specific service conditions.

7. If the valve was shipped without packing installedin the packing box, install the packing before puttingthe valve into service. Refer to instructions given inthe Packing Maintenance procedure.

MaintenanceValve parts are subject to normal wear and must beinspected and replaced as necessary. Inspectionand maintenance frequency depends on the severityof service conditions. This section includesinstructions for packing lubrication, packingmaintenance, adding packing rings, replacingpacking, trim removal, valve plug maintenance,lapping seats, and trim replacement. All

maintenance operations can be performed with thevalve in the line.

Because of the care Fisher takes in meeting allmanufacturing requirements (heat treating,dimensional tolerances, etc.) use only replacementparts manufactured or furnished by Fisher.

WARNING

Avoid personal injury from suddenrelease of process pressure. Beforeperforming any maintenanceoperations:

� Always wear protective gloves,clothing, and eyewear whenperforming any maintenanceoperations to avoid personal injury.

� Disconnect any operating linesproviding air pressure, electric power,or a control signal to the actuator. Besure the actuator cannot suddenlyopen or close the valve.

� Use bypass valves or completelyshut off the process to isolate thevalve from process pressure. Relieveprocess pressure on both sides of thevalve. Drain the process media fromboth sides of the valve.

� Vent the power actuator loadingpressure and relieve any actuatorspring precompression.

� Use lock-out procedures to besure that the above measures stay ineffect while you work on theequipment.

� The valve packing box maycontain process fluids that arepressurized, even when the valve hasbeen removed from the pipeline.Process fluids may spray out underpressure when removing the packinghardware or packing rings, or whenloosening the packing box pipe plug.

Note

Whenever a gasket seal is disturbedby removing or shifting gasketedparts, a new gasket should be installedupon reassembly. This is necessary toensure a good gasket seal.

Note

If the valve has HIGH-SEAL heavy-dutylive-loaded packing installed, seeFisher instruction manual entitledHIGH-SEAL Live-Loaded PackingSystem’ for packing instructions.

Packing Lubrication

Note

To avoid lubricants breaking down atelevated temperatures, do notlubricate packing used in processeswith temperatures over 260�C (500�F).

A lubricator or lubricator/isolating valve (figure 2) isrecommended for PTFE-composition packing. Thelubricator or lubricator/isolating valve is installed inplace of the pipe plug (key 14, figure 15). It isrecommended that a good quality silicon-baselubricant be used. To operate the lubricator, simplyturn the cap screw clockwise to force lubricant intothe packing box. The lubricator/isolating valveoperates the same way except the isolating valvemust first be opened and then closed afterlubrication is completed.

Packing MaintenanceIf there is undesirable packing leakage inspring-loaded PTFE V-ring packing (figure 3), tightenthe packing flange nuts (key 5, figure 15) until theshoulder on the packing follower (key 13, figure 15)contacts the bonnet (key 1, figure 15). If leakagecontinues, replace the packing by following thenumbered steps presented in the Replacing Packingprocedure.

If there is undesirable packing leakage with otherthan spring-loaded PTFE V-ring packing, first try tolimit the leakage and establish a stem seal bytightening the packing flange nuts (key 5, figure 15)to at least the minimum recommended torque intable 7. However, do not exceed the maximumrecommended torque in table 7 or excessive frictionmay result. If leakage continues, replace the packingby following the numbered steps presented in theReplacing Packing procedure.

If the packing is relatively new and tight on the valveplug stem, and if tightening the packing flange nutsdoes not stop the leakage, it is possible that thestem is worn or nicked so that a seal cannot bemade. The surface finish of a stem is critical formaking a good packing seal. If the leakage comesfrom the outside diameter of the packing, it ispossible that the leakage is caused by nicks orscratches around the packing box wall. Whilereplacing the packing according to the ReplacingPacking procedure, inspect the valve plug stem andpacking box wall for nicks or scratches.

Replacing PackingKey numbers referred to in this procedure are shownin figure 15 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 thevalve.

Remove the cap screws in the stem connector, andseparate the two halves of the stem connector. Thenexhaust all actuator pressure, if any was applied,and disconnect the actuator supply and any leakoffpiping.

2. Remove either the yoke locknut (key 15) or thehex nuts (key 26), and remove the actuator from thebonnet (key 1).

3. Loosen the packing flange nuts (key 5) so thatthe packing is not tight on the valve plug stem (key4, figure 17, 18, or 19). Remove any travel indicatordisk and stem locknuts from the valve plug stemthreads.

CAUTION

When lifting the bonnet (key 1), besure that the valve plug and stemassembly (keys 3 and 4, figure 17, 18,or 19) remains on the seat ring (key 6,figure 17, 18, or 19). This avoidsdamage to the seating surfaces as aresult of the assembly dropping fromthe bonnet after being lifted part wayout. The parts are also easier to handleseparately.Use care to avoid damaging gasketsealing surfaces.The Design EHD piston rings (key 8,figure 17) are brittle and in two pieces.Avoid damaging the piston rings bydropping or rough handling.

WARNING

If the cage adheres to the bonnet asthe bonnet is lifted, secure the cage tothe bonnet so that it will not causepersonal injury or equipment damageshould it fall unexpectedly.

4. Unscrew the hex nuts (key 14, figure 17, 18, or19) and carefully lift the bonnet off the valve stem. Ifthe valve plug and stem assembly starts to lift withthe bonnet, use a brass or lead hammer on the endof the stem and tap it back down. Set the bonnet ona cardboard or wooden surface to prevent damageto the bonnet gasket surface.5. Remove the valve plug (key 3, figure 17, 18, or19), the cage (key 2, figure 17, 18, or 19), and thetop and bottom cage gaskets (key 11, figure 17, 18,or 19).

CAUTION

All residual gasket material must beremoved from the the cage gasketsurfaces. If the gasket surfaces arescored or damaged during thisprocess, smooth them by handsanding with 360 grit paper using long,sweeping strokes. Failure to removeall residual gasket material and/orburrs from the gasket surfaces willresult in leakage.

6. Clean all gasket surfaces with a good qualitydegreaser. Remove all residual tin or silver from allgasket surfaces.

7. Cover the opening in the valve body to protectthe gasket surface and to prevent foreign materialfrom getting into the valve body cavity.

8. Remove the packing flange nuts (key 5), packingflange (key 3), upper wiper (key 12), and packingfollower (key 13, figures 3 and 15). Carefully pushout all the remaining packing parts from the valveside of the bonnet using a rounded rod or other toolthat will not scratch the packing box wall. Forextension bonnets, also remove the baffle (key 2)and retaining ring (key 35).

9. Clean the packing box and the following metalpacking parts: packing follower (key 13), packingbox ring (key 11), spring or lantern ring (key 8,figures 3 and 15), and, for single arrangements ofPTFE V-ring packing only, special washer (key 10,figures 3 and 15).

10. Inspect the valve stem threads for any sharpedges that might cut the packing. A whetstone oremery cloth may be used to smooth the threads ifnecessary.

11. Remove the protective covering from the valvebody cavity. Using new top and bottom cage gaskets(key 11, figure 17, 18, or 19), place the cage into thevalve body. Be sure the cage lugs are engaged inthe corresponding recesses of the seat ring retainer.Turn the cage clockwise until the lugs contact theseat ring retainer. Install the plug, then slide thebonnet over the stem and onto the studs (key 13,figure 17, 18, or 19).

Note

The prelubricated hex nuts (key 14,figure 17, 18, or 19) referred to in step12 can be identified by a black filmcoating on the nut threads.

The proper bolting procedures in step12 include—but are not limitedto—ensuring that the bonnet studthreads are clean, and that the hexnuts are evenly tightened to thespecified torque values.

CAUTION

Failure to comply with goodbonnet-to-body bolting practices andthe torque values shown in table 8 mayresult in cage crushing, cage diameterreduction, and/or bonnet deformation.

Cheater bars or slug wrenches shouldnot be used for this procedure.

Hot torquing is not recommended.

12. Lubricate the stud threads and the faces of thehex nuts (key 14, figure 17, 18, or 19) withNever-Seez Pure Nickel Special lubricant orequivalent (not necessary if new factoryprelubricated hex nuts are used). Replace thewashers and hex nuts but do not tighten them.Torque the nuts in a crisscross pattern to no morethan 1/4 of the nominal torque value specified intable 8. When all nuts are tightened to that torquevalue, increase the torque by 1/4 of the specifiednominal torque and repeat the crisscross pattern.Repeat this procedure until all nuts are tightened tothe specified nominal value. Apply the final torquevalue again and, if any nut still turns, tighten everynut again.

Note

If graphite ribbon/filament packingrings are used, special proceduresmust be observed to prevententrapping air between the rings. Addthe rings one at a time without forcingthem below the chamfer of the packingbox entrance chamber. As eachsuccessive ring is added, the stackshould not be pushed down more thanthe thickness of the added ring (figure 4).

13. Install new packing and the metal packing boxparts according to the appropriate arrangement infigure 3. If desired, packing parts may bepre-lubricated with a silicon base grease for easierinstallation. Slip a smooth-edged pipe over the valve

stem, and gently tamp each soft packing part intothe packing box, being sure that air is not trappedbetween adjacent soft parts. For a valve withextension bonnet, also install the baffle and retainingrings (keys 2 and 35).

14. Slide the packing follower, wiper, and packingflange into position. Lubricate the packing flangestuds (key 4) and the faces of the packing flangenuts (key 5). Replace the packing flange nuts.

For spring-loaded PTFE V-ring packing, tightenthe packing flange nuts until the shoulder on thepacking follower (key 13) contacts the bonnet.

For other packing types, tighten the packing flangenuts to the maximum recommended torque shown intable 7. Then, loosen the packing flange nuts, andretighten them to the recommended minimum torqueshown in table 7.

15. Mount the actuator on the valve body assembly,and reconnect the actuator and valve plug stemsaccording to the procedures in the appropriateactuator instruction manual.

Trim RemovalFor C-seal construction, see the appropriateC-seal sections in this instruction manual.

Trim removal and replacement requires the use of aseat ring retainer tool (key 25). If specificallyordered, a tool is supplied with a valve; but, the toolcan also be ordered separately by referencing thetool part number in the Parts List. If desired, a toolcan also be machined for a valve of specific size andvalve class using the dimensions shown in figure 7.Machine the tool from a material listed in figure 7 orfrom a material with a yield strength of at least 827MPa (120,000 psi). Using a tool of lower strengthmaterial may result in damage to the seat ringretainer or valve body threads.

Key numbers referenced in this procedure areshown in figure 17 for the Design EHD valve, figure18 for the Design EHS valve, and figure 19 for theDesign EHT valve except where indicated.

1. Remove the actuator and bonnet by followingsteps 1 through 4 of the Replacing Packingprocedure. Observe all warnings and cautions.

2. Lift the valve stem and attached valve plug out ofthe valve body. If the valve plug is to be reused, tapeor otherwise protect the valve plug stem and thevalve plug seating surface to prevent scratches.

3. Lift out the cage (key 2) and the top and bottomcage gaskets (key 11). For a valve with Cavitrol III

two-or three-stage cage, also remove the O-ring(key 26, figure 20) that fits between the cage and theseat ring (key 6).

Constructions other than TSO trim1. Use the seat ring retainer tool (figure 7) toremove the seat ring retainer (key 7) as follows:

a. Insert the tool into the valve body. Be certainthe tool lugs are engaged in the correspondingrecesses in the retainer.

b. Use a power torque wrench or driver havingtorque capabilities equal to or greater than thoseshown in table 9. Connect the torque wrench toan extension if necessary. The tool or extensionmust snugly fit the square hole in the seat ringretainer tool. Refer to figure 7 for square holesizes.

c. Insert the tool or extension into the squarehole in the seat ring retainer tool.

d. Use the bonnet studs (key 13) to prevent apower torque wrench from rotating.

CAUTION

Hold the torque wrench or driver atright angles to the seat ring retainerwhen applying torque. Tilting the toolor extension while applying torquemay cause the lugs on the seat ringretainer tool to suddenly disengagefrom the recesses in the retainer,damaging the retainer and seat ring.

e. Unscrew and remove the seat ring retainer.

2. Remove the seat ring (key 6) and the seat ringgasket or O-ring (key 12).

3. Refer to the Valve Plug Maintenance procedureor to the Lapping Seats procedure.

TSO TrimRefer to figure 6.

1. Remove the retainer, backup ring, anti-extrusionrings, and piston ring.

2. Remove the set screws that lock the outer plug tothe inner plug.

3. Using a strap wrench or similar tool, unscrew theouter plug from the inner plug. Do not damage theouter plug guide surfaces.

4. Remove the protected soft seat seal (see figure 5).

5. Inspect the parts for damage and replace if needed.

6. Refer to the Valve Plug Maintenance procedureor to the Lapping Seats procedure.

Valve Plug MaintenanceKey numbers used in this procedure are shown infigure 17 for the Design EHD valve, in figure 18 forthe Design EHS valve, and in figure 19 for theDesign EHT valve.

1. With the valve plug (key 3) removed according tothe Trim Removal procedure, proceed asappropriate:

For the Design EHD valve, the piston rings (key 8)are each in two sections; remove the sections fromthe grooves in the valve plug.

For the Design EHS valve, proceed to step 2.

For the Design EHT valve, work the retaining ring(key 10) off the valve plug with a screwdriver.Carefully slide the backup ring and seal ring (keys 9

and 8) off the valve plug. For a 6-inch valve with alevel D Whisper Trim III cage, also remove thepiston ring (key 30) from the grooves in the valveplug.

2. To replace the valve plug stem (key 4), drive outthe pin (key 5), and unscrew the stem from the valveplug.

CAUTION

Never reuse an old stem with a newvalve plug. Using an old stem with anew plug requires drilling a new pinhole in the stem. This weakens thestem and may cause the stem to fail inservice. If a new valve plug is required,always order a valve plug, stem, andpin as an assembly. Specify thecorrect part number of each of thethree parts, but state that the parts arebeing ordered as an assembly.

A used valve plug may be reused witha new stem. An exception is theCavitrol III plug/stem assembly whichmust be ordered and replaced as aunit.

3. Thread the new stem into the valve plug andtighten it to the appropriate torque value given intable 10. Using the valve plug pin hole as a guide,drill the pin hole through the stem. Refer to table 10for drill sizes.

4. Drive in the pin to lock the assembly.

5. If it is necessary to lap the seating surfaces,complete the Lapping Seats procedure beforeinstalling the Design EHD piston rings or the DesignEHT seal ring. The Trim Replacement procedureprovides piston ring and seal ring installationinstructions and valve reassembly instructions.

Lapping SeatsKey numbers referenced in this procedure areshown in figure 17 for the Design EHD valve, infigure 18 for the Design EHS valve, and in figure 19for the Design EHT valve unless otherwise indicated.

Seating surfaces of the valve plug (key 3) and theseat ring (key 6) can be lapped for improved shutoff.Use a good quality lapping compound with a mixturethat contains 280 to 600 grit. Apply the compound tothe bottom of the valve plug. Use the followingprocedure to lap the seating surfaces.

1. Install the following parts according to theinstructions presented in the Trim Replacementprocedure: seat ring gasket or O-ring (key 12), seatring (key 6), seat ring retainer (key 7), cage (key 2),cage gaskets (key 11), and if used, the O-ring (key26, figure 20).

2. Proceed as appropriate:

For a Design EHD or EHT valve, install the valveplug and stem assembly (keys 3 and 4)—withoutpiston rings or seal ring (keys 8 and 30)—into thecage.

For a Design EHS valve, install the valve plug andstem assembly (keys 3 and 4) into the cage.

3. Install the bonnet (key 1, figure 15) over the valvestem, and secure the bonnet with four of the hexnuts (key 14).

4. Attach a handle, such as a piece of strap ironsecured by stem locknuts, to the valve stem. Rotatethe handle alternately in each direction to lap theseats.

Note

To preserve the effects of lapping, donot change either the position of theseat ring in the valve body cavity orthe position of the cage on the seatring after lapping the seating surfaces.If possible, clean the parts withoutdisturbing their positions. If the partsmust be removed for cleaning, returnthem to the original positions.

5. After lapping, again disassemble as necessary,clean the seating surfaces, reassemble, and test forshutoff. Repeat the lapping procedure if necessary.

Trim ReplacementAfter all trim maintenance has been completed,reassemble the valve by following the numberedsteps below. Be certain that all gasketed surfaceshave been well cleaned. Key numbers referenced inthis procedure are shown in figure 17 for the DesignEHD valve, in figure 18 for the Design EHS valve,and in figure 19 for the Design EHT valve.

CAUTION

Thoroughly clean the seat ring (key 6),seat ring retainer (key 7), and theretainer threads in the valve body witha good-quality degreaser. Also cleanall cage gasket surfaces. All residualgasket material must be removed fromthe cage gasket surfaces and, ingasketed seat ring constructions, fromthe serrated valve body and seat ringgasket surfaces. If the serrations arescored or damaged during thisprocess, smooth them by handsanding with 360 grit paper using long,sweeping strokes. Failure to removeall residual gasket material and/orburrs from the seat ring, cage, andvalve body gasket surfaces will resultin leakage.

Thoroughly lubricate the surfacesindicated in figure 8 with theappropriate lubricant shown in table11. Be certain to lubricate the matingsurfaces of both parts involved (i.e.,lubricate the threads on the seat ringretainer and the threads in the valvebody; lubricate the mating surfaces ofthe seat ring retainer and seat ring).

Failure to lubricate as described maycause galling and improper gasket orO-ring (key 12) loading that may resultin leakage.

1. For gasketed seat ring constructions, install theseat ring gasket (key 12) into the valve body. ForO-ring seat ring constructions, install the O-ring (key12) into the groove on the underside of the seat ring(key 6). Install the seat ring (key 6). Screw in theseat ring retainer (key 7). Use the seat ring retainertool (figure 7) to tighten the seat ring retainer asfollows:

a. Insert the tool into the valve body. Be certainthe tool lugs are engaged in the correspondingrecesses in the retainer.

b. Use a power torque wrench or driver havingtorque capabilities equal to or greater than thoseshown in table 9. Connect the torque tool to anextension if necessary. The tool or extensionmust snugly fit the square hole in the seat ringretainer tool. Refer to figure 7 for square holesizes.

c. Insert the tool or extension into the squarehole in the seat ring retainer tool.

d. Use the stud bolts (key 13) to prevent a powertorque wrench from rotating.

CAUTION

Hold the torque wrench at right anglesto the seat ring retainer when applyingtorque. Tilting the tool and extensionwhile applying torque may cause thelugs on the seat ring retainer tool tosuddenly disengage from the recessesin the retainer, damaging the retainerand seat ring.

e. Tighten the seat ring retainer to the torqueshown in table 9.

Note

Some cages have one large windowand several small windows. In step 2,install a cage that has different sizewindows so that the largest windowfaces toward the process outlet for aflow-down and toward the processinlet for a flow-up valve. Though it maynot be possible to align the largewindow directly opposite the inlet oroutlet, orient the window in theappropriate direction as much aspossible. Incorrect orientation of cagewindows causes a reduction ofcapacity.

2. Proceed as appropriate:

For a valve with a Cavitrol III cage, slide the O-ring(key 26, figure 20) over the seat ring (key 6) andagainst the shoulder in the outer diameter of the seatring. Install the lower gasket (key 11) between thevalve body and cage (key 2), and install the cage.Be certain the lugs on the bottom of the cageengage the corresponding slots in the seat ringretainer.

For all other valves, install the lower gasket (key11) between the valve body and cage (key 2), andinstall the cage. Be certain the lugs on the bottom ofthe cage engage the corresponding slots in the seatring retainer.

Note

Rotate the cage clockwise by hand asmuch as possible once the cage lugsengage the slots in the seat ringretainer. Failure to do so may result inleakage at the seat ring to valve bodyseal.

Constructions other than TSO trim1. To install the piston rings and seal rings (keys 8and 30), proceed as appropriate:

For a Design EHD valve (figure 17), if it isnecessary to install new piston rings, thereplacement piston rings will arrive in one piece. Usea vise with smooth or taped jaws to break areplacement piston ring into halves. Place the newring in the vise so that the jaws compress the ringinto an oval. Compress the ring slowly until the ringsnaps on both sides. If one side snaps first, do nottry to tear or cut the other side. Instead, keepcompressing until the other side snaps. The piston

ring can also be fractured by scoring and snappingover a hard surface such as a table edge. Sawing orcutting is not recommended.

Remove any protective tape or covering from thevalve plug and stem assembly, and set it on aprotective surface. Then, place the piston ring in thepiston ring groove with the fractured ends matched.

For a Design EHT valve (figure 19), install the sealring (key 8) onto the valve plug (key 3). Install thering with the open side facing the seat ring end ofthe valve plug for flow-down applications (view A offigure 19) or with the open side facing the valve plugstem end of the valve plug for flow-up applications.Slide the backup ring (key 9) onto the valve plug.Secure with the retaining ring (key 10). For a 6-inchvalve with a level D Whisper Trim III cage, reinstallthe piston ring (key 30) following the instructionsgiven in the paragraph immediately preceding.

2. Install the valve plug into the cage.

Note

The prelubricated hex nuts (key 14,figure 17, 18, or 19) referred to in step7 can be identified by a black filmcoating on the nut threads.

The proper bolting procedures in step7 include—but are not limitedto—ensuring that the bonnet studthreads are clean, and that the hexnuts are evenly tightened to thespecified torque values.

CAUTION

Failure to comply with goodbonnet-to-body bolting practices andthe torque values shown in table 8 mayresult in cage crushing, cage diameterreduction, and/or bonnet deformation.Cheater bars or slug wrenches shouldnot be used for this procedure.

Hot torquing is not recommended.

3. Lubricate the stud threads and the faces of thehex nuts (key 14, figure 17, 18, or 19) withNever-Seez Pure Nickel Special lubricant orequivalent (not necessary if new factoryprelubricated hex nuts are used). Replace thewashers and hex nuts but do not tighten them.Torque the nuts in a crisscross pattern to no morethan 1/4 of the nominal torque value specified intable 8. When all nuts are tightened to that torquevalue, increase the torque by 1/4 of the specifiednominal torque and repeat the crisscross pattern.Repeat this procedure until all nuts are tightened tothe specified nominal value. Apply the final torquevalue again and, if any nut still turns, tighten everynut again.

4. Install new packing and packing box parts persteps 12 and 13 of the Replacing Packingprocedure. Be certain to observe the note given priorto step 12 of that procedure.

5. Mount the actuator by following the procedures inthe actuator instruction manual. Check for packingleakage as the valve is being put into service.Retorque the packing flange nuts as required (seetable 7).

Retrofit: Installing C-seal Trim

Note

Additional actuator thrust is requiredfor a valve with C-seal trim. Wheninstalling C-seal trim in an existingvalve, contact your Fisher sales officefor assistance in determining newactuator thrust requirements.

Assemble the new valve plug/retainer assembly(with C-seal plug seal) using the followinginstructions:

CAUTION

To avoid leakage when the valve isreturned to service, use appropriatemethods and materials to protect allsealing surfaces of the new trim partswhile assembling the individual partsand during installation in the valvebody.

1. Apply a suitable high-temperature lubricant to theinside diameter of the C-seal plug seal. Also,lubricate the outside diameter of the valve plugwhere the C-seal plug seal must be pressed into theproper sealing position (figure 9).

2. Orient the C-seal plug seal for correct sealingaction based on the process fluid flow directionthrough the valve.

� The open interior of the C-seal plug seal mustface up in a valve with flow-up construction (figure9).

� The open interior of the C-seal plug seal mustface down in a valve with flow-down construction(figure 9).
