DescriptionThe Design EHD, EHS, and EHT high-pressure globevalves (figure 1) have metal seats, cage guiding, andpush-down-to-close valve plug action. The Design

EHD and EHT valves use balanced valve plugs. TheDesign EHS valve uses an unbalanced valve plug. Toprovide a seal between the cage and a balanced valveplug, the Design EHD valve plug uses piston rings; theDesign EHT valve plug uses a pressure-assisted sealring. A Whisper Trim cage can be used with a DesignEHD, EHS, or EHT valve plug. A Cavitrol III cage canbe used with a Design EHS 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 achieve high-temperature, Class V shutoff. Because the C-seal plugseal is formed from metal (N07718 nickel alloy, Inconel718) rather than an elastomer, a valve equipped withthe C-seal trim can be applied in processes with a fluidtemperature of up to 1100�F (593�C), provided othermaterial limits are not exceeded.

Installation

WARNING

To avoid personal injury or propertydamage resulting from the sudden re-lease of pressure, do not install thevalve assembly where service condi-tions could exceed the limits given inthis manual or on the appropriate name-plates. Use pressure-relieving devicesas required by government or acceptedindustry codes and good engineeringpractices.

CAUTION

The valve configuration and construc-tion materials were selected to meet par-ticular pressure, temperature, pressuredrop, and controlled fluid conditions.Because some body/trim material com-binations are limited in their pressuredrop and temperature range capabilities(especially due to differences in thermalexpansion rates), do not apply any otherconditions to the valve without first con-tacting your Fisher Controls sales office.

CAUTION

If hoisting the valve, use a nylon sling toprotect the painted surfaces. Carefullyposition the sling to prevent damage tothe tubing or any accessories. Also, takeprecautions to prevent personnel frombeing injured in case the hoist or riggingslips unexpectedly. Refer to table 6 forvalve assembly weights. Using ade-quately sized hoists and chains or slingsto handle the valve is important.

1. Before installing the valve, inspect it to ensure thatthe 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 small in-ternal flow passages, such as with Whis-per Trim III or Cavitrol III cages, consid-eration should be given to installing anupstream strainer to prevent the lodgingof particles in these passages. This isespecially important if the pipeline can-not be thoroughly cleaned or if the flow-ing medium is not clean.

3. The control valve must be installed with the actua-tor vertical above the valve body for proper operation.Flow through the valve must be in the direction indi-cated by the flow arrow (key 15, figure 17, 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 removing alltrim parts before welding the valve body in the line. Forflanged valve bodies, use suitable gaskets betweenthe valve body flanges and pipeline flanges.

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 isneeded, remove all trim parts. Contactyour Fisher Controls sales office foradditional information.

5. Install a three-valve bypass around the valve if con-tinuous operation is required during maintenance.

6. If the actuator and valve body are shipped sepa-rately, refer to the actuator mounting procedure in theappropriate actuator instruction manual.

WARNING

Personal injury could result from pack-ing leakage. Valve packing was tight-ened prior to shipment; however somereadjustment will be required to meetspecific service conditions.

7. If the valve was shipped without packing installed inthe packing box, install the packing before putting thevalve into service. Refer to instructions given in thePacking Maintenance procedure.

MaintenanceValve parts are subject to normal wear and must beinspected and replaced as necessary. Inspection andmaintenance frequency depends on the severity ofservice conditions. This section includes instructionsfor packing lubrication, packing maintenance, addingpacking rings, replacing packing, trim removal, valveplug maintenance, lapping seats, and trim replace-ment. All maintenance operations can be performedwith the valve in the line.

Because of the care Fisher Controls takes in meetingall manufacturing requirements (heat treating, dimen-sional tolerances, etc.) use only replacement partsmanufactured or furnished by Fisher Controls.

WARNING

Avoid personal injury from sudden re-lease of process pressure. Before per-forming any maintenance operations:

� Always wear protective gloves,clothing, and eyewear when performingany maintenance operations to avoidpersonal injury.

� Disconnect any operating lines pro-viding air pressure, electric power, or acontrol signal to the actuator. Be sure


5

the actuator cannot suddenly open orclose the valve.

� Use bypass valves or completelyshut off the process to isolate the valvefrom process pressure. Relieve processpressure on both sides of the valve.Drain the process media from both sidesof the valve.

� Vent the power actuator loadingpressure and relieve any actuator springprecompression.

� Use lock-out procedures to be surethat the above measures stay in effectwhile you work on the equipment.

� The valve packing box may containprocess fluids that are pressurized, evenwhen the valve has been removed fromthe pipeline. Process fluids may sprayout under pressure when removing thepacking hardware or packing rings, orwhen loosening the packing box pipeplug.

Note

Whenever a gasket seal is disturbed byremoving or shifting gasketed parts, anew gasket should be installed uponreassembly. This is necessary to ensurea good gasket seal.

Note

If the valve has HIGH-SEAL heavy-dutylive-loaded packing installed, see FisherControls instruction manual entitledHIGH-SEAL Live-Loaded Packing Sys-tem’ for packing instructions.

Packing LubricationA 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 is recom-

mended that a good quality silicon-base lubricant beused. Do not lubricate packing used in processes withtemperatures over 500�F (260�C). To operate the lu-bricator, simply turn the cap screw clockwise to forcelubricant into the packing box. The lubricator/isolatingvalve operates the same way except the isolatingvalve must first be opened and then closed after lu-brication is completed.

Packing MaintenanceIf there is undesirable packing leakage in spring-loaded PTFE V-ring packing (figure 3), tighten thepacking flange nuts (key 5, figure 15) until the shoulderon the packing follower (key 13, figure 15) contacts thebonnet (key 1, figure 15). If leakage continues, replacethe packing by following the numbered steps pres-ented in the Replacing Packing procedure.

If there is undesirable packing leakage with other thanspring-loaded PTFE V-ring packing, first try to limit theleakage and establish a stem seal by tightening thepacking flange nuts (key 5, figure 15) to at least theminimum recommended torque in table 7. However,do not exceed the maximum recommended torque intable 7 or excessive friction may result. If leakage con-tinues, replace the packing by following the numberedsteps presented in the Replacing 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 the stemis worn or nicked so that a seal cannot be made. The surface finish of a stem is critical for making agood packing seal. If the leakage comes from the out-side diameter of the packing, it is possible that theleakage is caused by nicks or scratches around thepacking box wall. While replacing the packing accord-ing to the Replacing Packing procedure, inspect thevalve plug stem and packing box wall for nicks orscratches.

Replacing PackingKey numbers referred to in this procedure are shownin figure 15 unless otherwise indicated.

1. Isolate the control valve from the line pressure, re-lease pressure from both sides of the valve body, anddrain the process media from both sides of the valve.

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

2. Remove either the yoke locknut (key 15) or the hexnuts (key 26), and remove the actuator from the bon-net (key 1).

3. Loosen the packing flange nuts (key 5) so that thepacking is not tight on the valve plug stem (key 4, fig-ure 17, 18, or 19). Remove any travel indicator diskand stem locknuts from the valve plug stem threads.

CAUTION

When lifting the bonnet (key 1), be surethat the valve plug and stem assembly(keys 3 and 4, figure 17, 18, or 19) re-mains on the seat ring (key 6, figure 17,18, or 19). This avoids damage to theseating surfaces as a result of the as-sembly dropping from the bonnet afterbeing lifted part way out. The parts arealso easier to handle separately.

Use care to avoid damaging gasket seal-ing surfaces.

The Design EHD piston rings (key 8, fig-ure 17) are brittle and in two pieces.Avoid damaging the piston rings bydropping or rough handling.

WARNING

If the cage adheres to the bonnet as thebonnet is lifted, secure the cage to thebonnet so that it will not cause personalinjury or equipment damage should itfall unexpectedly.

4. Unscrew the hex nuts (key 14, figure 17, 18, or 19)and carefully lift the bonnet off the valve stem. If thevalve plug and stem assembly starts to lift with thebonnet, use a brass or lead hammer on the end of thestem and tap it back down. Set the bonnet on a card-board or wooden surface to prevent damage to thebonnet gasket surface.

5. Remove the valve plug (key 3, figure 17, 18, or 19),the cage (key 2, figure 17, 18, or 19), and the top andbottom cage gaskets (key 11, figure 17, 18, or 19).

CAUTION

All residual gasket material must be re-moved from the the cage gasket sur-faces. If the gasket surfaces are scoredor damaged during this process, smooththem by hand sanding with 360 grit pa-per using long, sweeping strokes. Fail-ure to remove all residual gasket materi-al and/or burrs from the gasket surfaceswill result in leakage.

6. Clean all gasket surfaces with a good quality de-greaser. Remove all residual tin or silver from all gas-ket surfaces.

7. Cover the opening in the valve body to protect thegasket surface and to prevent foreign material fromgetting into the valve body cavity.

8. Remove the packing flange nuts (key 5), packingflange (key 3), upper wiper (key 12), and packing fol-lower (key 13, figures 3 and 15). Carefully push out allthe remaining packing parts from the valve side of thebonnet using a rounded rod or other tool that will notscratch the packing box wall. For extension bonnets,also remove the baffle (key 2) and retaining ring (key35).

9. Clean the packing box and the following metalpacking parts: packing follower (key 13), packing boxring (key 11), spring or lantern ring (key 8, figures 3and 15), and, for single arrangements of PTFE V-ringpacking only, special washer (key 10, figures 3 and15).

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 if nec-essary.

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 in thecorresponding recesses of the seat ring retainer. Turnthe cage clockwise until the lugs contact the seat ringretainer. Install the plug, then slide the bonnet over thestem and onto the studs (key 13, figure 17, 18, or 19).

Note

The prelubricated hex nuts (key 14, fig-ure 17, 18, or 19) referred to in step 12can be identified by a black film coatingon the nut threads.

The proper bolting procedures in step 12include—but are not limited to—ensur-ing that the bonnet stud threads areclean, and that the hex nuts are evenlytightened to the specified torque values.

CAUTION

Failure to comply with good bonnet-to-body bolting practices and the torquevalues shown in table 8 may result incage crushing, cage diameter reduction,and/or bonnet deformation. Cheater barsor slug wrenches should not be used forthis procedure.

Hot torquing is not recommended.

12. Lubricate the stud threads and the faces of thehex nuts (key 14, figure 17, 18, or 19) with Never-Seez(1) Pure Nickel Special lubricant or equivalent

(not necessary if new factory prelubricated hex nutsare used). Replace the washers and hex nuts but donot tighten them. Torque the nuts in a crisscross pat-tern to no more than 1/4 of the nominal torque valuespecified in table 8. When all nuts are tightened to thattorque value, increase the torque by 1/4 of the speci-fied nominal torque and repeat the crisscross pattern.Repeat this procedure until all nuts are tightened to thespecified nominal value. Apply the final torque valueagain and, if any nut still turns, tighten every nut again.

Note

If graphite ribbon/filament packing ringsare used, special procedures must beobserved to prevent entrapping air be-tween the rings. Add the rings one at atime without forcing them below thechamfer of the packing box entrancechamber. As each successive ring isadded, the stack should not be pusheddown more than the thickness of theadded ring (figure 4).

13. Install new packing and the metal packing boxparts according to the appropriate arrangement in fig-ure 3. If desired, packing parts may be pre-lubricatedwith a silicon base grease for easier installation. Slip asmooth-edged pipe over the valve stem, and gentlytamp each soft packing part into the packing box, be-ing sure that air is not trapped between adjacent softparts. For a valve with extension bonnet, also installthe baffle and retaining rings (keys 2 and 35).

14. Slide the packing follower, wiper, and packingflange into position. Lubricate the packing flange studs(key 4) and the faces of the packing flange nuts (key5). Replace the packing flange nuts.

For spring-loaded PTFE V-ring packing, tighten thepacking flange nuts until the shoulder on the packingfollower (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, and re-tighten 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 stems ac-cording to the procedures in the appropriate actuatorinstruction manual.

Trim RemovalFor C-seal construction, see the appropriate C-sealsections in this instruction manual.

Trim removal and replacement requires the use of aseat ring retainer tool (key 25). If specifically ordered,a tool is supplied with a valve; but, the tool can also beordered separately by referencing the tool part numberin the Parts List. If desired, a tool can also be ma-chined for a valve of specific size and valve class us-ing the dimensions shown in figure 7. Machine the toolfrom a material listed in figure 7 or from a material witha yield strength of at least 120,000 psi (827 MPa). Us-ing a tool of lower strength material may result in dam-age to the seat ring retainer or valve body threads.

Key numbers referenced in this procedure are shownin figure 17 for the Design EHD valve, figure 18 for theDesign EHS valve, and figure 19 for the Design EHTvalve except where indicated.

1. Remove the actuator and bonnet by following steps1 through 4 of the Replacing Packing procedure. Ob-serve 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 the valveplug 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 the seat ring(key 6).

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

a. Insert the tool into the valve body. Be certain thetool lugs are engaged in the corresponding re-cesses 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 to an

Valve Plug MaintenanceKey numbers used in this procedure are shown in fig-ure 17 for the Design EHD valve, in figure 18 for theDesign EHS valve, and in figure 19 for the Design EHTvalve.

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

For the Design EHD valve, the piston rings (key 8)are each in two sections; remove the sections from thegrooves 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. Carefullyslide the backup ring and seal ring (keys 9 and 8) offthe valve plug. For a 6-inch valve with a level D Whis-per Trim III cage, also remove the piston ring (key 30)from the grooves in the valve plug.

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 a new

plug requires drilling a new pin hole inthe stem. This weakens the stem andmay cause the stem to fail in service. If anew valve plug is required, always ordera valve plug, stem, and pin as an assem-bly. Specify the correct part number ofeach of the three parts, but state that theparts are being ordered as an assembly.

A used valve plug may be reused with anew stem. An exception is the Cavitrol IIIplug/stem assembly which must be or-dered and replaced as a unit.

3. Thread the new stem into the valve plug and tight-en it to the appropriate torque value given in table 10.Using the valve plug pin hole as a guide, drill the pinhole through the stem. Refer to table 10 for drill sizes.

4. Drive in the pin to lock the assembly.

5. If it is necessary to lap the seating surfaces, com-plete the Lapping Seats procedure before installing theDesign EHD piston rings or the Design EHT seal ring.The Trim Replacement procedure provides piston ringand seal ring installation instructions and valve reas-sembly instructions.

Lapping SeatsKey numbers referenced in this procedure are shownin figure 17 for the Design EHD valve, in figure 18 forthe Design EHS valve, and in figure 19 for the DesignEHT valve unless otherwise indicated.

Seating surfaces of the valve plug (key 3) and the seatring (key 6) can be lapped for improved shutoff. Use agood quality lapping compound with a mixture thatcontains 280 to 600 grit. Apply the compound to thebottom of the valve plug. Use the following procedureto lap the seating surfaces.

1. Install the following parts according to the instruc-tions presented in the Trim Replacement procedure:seat ring gasket or O-ring (key 12), seat ring (key 6),seat ring retainer (key 7), cage (key 2), cage gaskets(key 11), and if used, the O-ring (key 26, figure 20).

2. Proceed as appropriate:

For a Design EHD or EHT valve, install the valveplug and stem assembly (keys 3 and 4)—without pis-ton rings or seal ring (keys 8 and 30)—into the cage.

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 hex nuts(key 14).

4. Attach a handle, such as a piece of strap iron se-cured by stem locknuts, to the valve stem. Rotate thehandle alternately in each direction to lap the seats.

Note

To preserve the effects of lapping, donot change either the position of theseat ring in the valve body cavity or theposition of the cage on the seat ring af-ter lapping the seating surfaces. If pos-sible, clean the parts without disturbingtheir positions. If the parts must be re-moved for cleaning, return them to theoriginal 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, reas-semble the valve by following the numbered steps be-low. Be certain that all gasketed surfaces have beenwell cleaned. Key numbers referenced in this proce-dure are shown in figure 17 for the Design EHD valve,in figure 18 for the Design EHS valve, and in figure 19for the Design EHT valve.

CAUTION

Thoroughly clean the seat ring (key 6),seat ring retainer (key 7), and the retain-er threads in the valve body with a good-quality degreaser. Also clean all cagegasket surfaces. All residual gasket ma-terial must be removed from the cagegasket surfaces and, in gasketed seatring constructions, from the serratedvalve body and seat ring gasket sur-faces. If the serrations are scored ordamaged during this process, smooththem by hand sanding with 360 grit pa-per using long, sweeping strokes. Fail-ure to remove all residual gasket materi-al and/or burrs from the seat ring, cage,and valve body gasket surfaces will re-sult in leakage.

VALVE BODY

LUBRICATION REQUIRED

1

1

1

Thoroughly lubricate the surfaces indi-cated in figure 8 with the appropriate lu-bricant shown in table 11. Be certain tolubricate the mating surfaces of bothparts involved (i.e., lubricate the threadson the seat ring retainer and the threadsin the valve body; lubricate the matingsurfaces of the seat ring retainer andseat ring).

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

1. For gasketed seat ring constructions, install theseat ring gasket (key 12) into the valve body. For O-ring seat ring constructions, install the O-ring (key 12)into the groove on the underside of the seat ring (key6). Install the seat ring (key 6). Screw in the seat ringretainer (key 7). Use the seat ring retainer tool (figure7) to tighten the seat ring retainer as follows:

a. Insert the tool into the valve body. Be certain thetool lugs are engaged in the corresponding re-cesses 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 an ex-tension if necessary. The tool or extension mustsnugly fit the square hole in the seat ring retainertool. Refer to figure 7 for square hole sizes.


14

c. Insert the tool or extension into the square holein 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 angles tothe seat ring retainer when applyingtorque. Tilting the tool and extensionwhile applying torque may cause thelugs on the seat ring retainer tool to sud-denly disengage from the recesses inthe retainer, damaging the retainer andseat ring.

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

Note

Some cages have one large window andseveral small windows. In step 2, installa cage that has different size windowsso that the largest window faces towardthe process outlet for a flow-down andtoward the process inlet for a flow-upvalve. Though it may not be possible toalign the large window directly oppositethe inlet or outlet, orient the window inthe appropriate direction as much aspossible. Incorrect orientation of cagewindows causes a reduction of capacity.

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. Becertain the lugs on the bottom of the cage engage thecorresponding slots in the seat ring retainer.

For all other valves, install the lower gasket (key 11)between the valve body and cage (key 2), and installthe cage. Be certain the lugs on the bottom of the cageengage the corresponding slots in the seat ring retain-er.

Note

Rotate the cage clockwise by hand asmuch as possible once the cage lugs en-gage the slots in the seat ring retainer.

Failure to do so may result in leakage atthe seat ring to valve body seal.

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 is necessaryto install new piston rings, the replacement piston ringswill arrive in one piece. Use a vise with smooth ortaped jaws to break a replacement piston ring intohalves. Place the new ring in the vise so that the jawscompress the ring into an oval. Compress the ringslowly until the ring snaps on both sides. If one sidesnaps 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 andsnapping over a hard surface such as a table edge.Sawing or cutting is not recommended.

Remove any protective tape or covering from the valveplug and stem assembly, and set it on a protective sur-face. Then, place the piston ring in the piston ringgroove with the fractured ends matched.

For a Design EHT valve (figure 19), install the seal ring(key 8) onto the valve plug (key 3). Install the ring withthe open side facing the seat ring end of the valve plugfor flow-down applications (view A of figure 19) or withthe open side facing the valve plug stem end of thevalve plug for flow-up applications. Slide the backupring (key 9) onto the valve plug. Secure with the retain-ing ring (key 10). For a 6-inch valve with a level DWhisper Trim III cage, reinstall the piston ring (key 30)following the instructions given in the paragraph im-mediately preceding.

2. Install the valve plug into the cage.

TSO TrimRefer to figure 6.

1. Thread the outer plug onto the inner plug until theparts seat metal to metal, using a strap wrench or simi-lar tool that will not damage the outer plug guide sur-faces.

2. Mark the top of the inner plug and outer plug withalignment marks in the assembled position.

3. Disassemble the outer plug from the inner plug andinstall the seal over the inner plug, so that the sealrests below the threaded area.

4. Thread the outer plug onto the inner plug and tight-en with a strap wrench or similar tool until the align-ment marks line up. This will ensure that the plug partsare metal to metal and the seal is compressed proper-ly. Do not damage the outer plug guide surfaces.


15

5. Install set screws centering the inner plug in theouter plug and torque to 8 lbf�ft.

6. Assemble the piston ring, anti-extrusion rings,backup ring, and retainer.

All Constructions1. Install the top cage gasket (key 11) on the cage.

2. Install the bonnet over the valve stem and onto thevalve body.

Note

The prelubricated hex nuts (key 14, fig-ure 17, 18, or 19) referred to in step 7 canbe identified by a black film coating onthe nut threads.

The proper bolting procedures in step 7include—but are not limited to—ensur-ing that the bonnet stud threads areclean, and that the hex nuts are evenlytightened to the specified torque values.

CAUTION

Failure to comply with good bonnet-to-body bolting practices and the torquevalues shown in table 8 may result incage crushing, cage diameter reduction,and/or bonnet deformation. Cheater barsor slug wrenches should not be used forthis procedure.

Hot torquing is not recommended.

3. Lubricate the stud threads and the faces of the hexnuts (key 14, figure 17, 18, or 19) with Never-SeezPure Nickel Special lubricant or equivalent (not neces-sary if new factory prelubricated hex nuts are used).Replace the washers and hex nuts but do not tightenthem. Torque the nuts in a crisscross pattern to nomore than 1/4 of the nominal torque value specified intable 8. When all nuts are tightened to that torque val-ue, increase the torque by 1/4 of the specified nominaltorque and repeat the crisscross pattern. Repeat thisprocedure until all nuts are tightened to the specifiednominal value. Apply the final torque value again and,if any nut still turns, tighten every nut again.

4. Install new packing and packing box parts per steps12 and 13 of the Replacing Packing procedure. Becertain to observe the note given prior to step 12 ofthat procedure.

5. Mount the actuator by following the procedures inthe actuator instruction manual. Check for packing

leakage as the valve is being put into service. Retor-que the packing flange nuts as required (see table 7).

Retrofit: Installing C-seal Trim

Note

Additional actuator thrust is required fora valve with C-seal trim. When installingC-seal trim in an existing valve, contactyour Fisher Controls sales office for as-sistance in determining new actuatorthrust requirements.

Assemble the new valve plug/retainer assembly (withC-seal plug seal) using the following instructions:

CAUTION

To avoid leakage when the valve is re-turned to service, use appropriate meth-ods and materials to protect all sealingsurfaces of the new trim parts while as-sembling the individual parts and duringinstallation in the valve body.

1. Apply a suitable high-temperature lubricant to theinside diameter of the C-seal plug seal. Also, lubricatethe outside diameter of the valve plug where theC-seal plug seal must be pressed into the proper seal-ing position (figure 9).

2. Orient the C-seal plug seal for correct sealing ac-tion based on the process fluid flow direction throughthe valve.

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

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

37B1047-A / IL

Note

An installation tool must be used toproperly position the C-seal plug seal onthe valve plug. A tool is available as aspare part from Fisher Controls or a toolcould be manufactured following the di-mensions given in figure 10.

3. Place the C-seal plug seal over the top of the valveplug and press the C-seal plug seal onto the plug us-ing the C-seal installation tool. Carefully press theC-seal plug seal onto the plug until the installation toolcontacts the horizontal reference surface of the valveplug (figure 11).

4. Apply a suitable high-temperature lubricant to thethreads on the plug. Then, place the C-seal retaineronto the plug and tighten the retainer using an ap-propriate tool such as a strap wrench.

5. Using an appropriate tool such as a center punch,stake the threads on top of the plug in one place (fig-ure 12) to secure the C-seal retainer.

6. Install the new plug/retainer assembly with C-sealplug seal on the new stem following the appropriateinstructions in the Trim Replacement section of thismanual.

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

8. Remove the existing valve actuator and bonnet fol-lowing the appropriate instructions in the ReplacingPacking section of this manual.

CAUTION

Do not remove the existing valve stemfrom the valve plug unless you are plan-ning to replace the valve stem.

Never reuse an old valve stem with anew plug or reinstall a valve stem after ithas been removed. Replacing a valvestem requires drilling a new pin hole inthe stem. This drilling weakens the stemand may cause failure in service. Howev-er, a used valve plug may be reused witha new valve stem.

9. Remove the existing valve stem and plug, cage,and seat ring from the valve body following the ap-propriate instructions in the Trim Removal section ofthis manual.

10. Replace all gaskets according to appropriateinstructions in the Trim Replacement section of thismanual.

11. Install the new seat ring, cage, valve plug/retainerassembly, and stem into the valve body and complete-ly reassemble the valve package following the ap-propriate instructions in the Trim Replacement sectionof this manual.

CAUTION

To avoid excessive leakage and seaterosion, the valve plug must be initiallyseated with sufficient force to overcomethe resistance of the C-seal plug sealand contact the seat ring. You can cor-rectly seat the valve plug by using thesame force calculated for full load whensizing your actuator. With no pressuredrop through the valve, this force willadequately drive the valve plug to theseat ring, thus giving the C-seal plugseal a predetermined permanent set.Once this is done, the plug/retainer as-sembly, the cage, and the seat ring be-come a matched set.

12. With full actuator force applied and the valve plugfully seated, align the actuator travel indicator scalewith the lower end of valve travel. Refer to the ap-propriate actuator instruction manual for information onthis procedure.

Replacement of Installed C-seal Trim

Trim Removal (C-seal Constructions)1. Remove the valve actuator and bonnet followingthe appropriate instructions in the Replacing Packingsection of this manual.

CAUTION

To avoid leakage when the valve is re-turned to service, use appropriate meth-

ods and materials to protect all sealingsurfaces of the trim parts during mainte-nance.

Use caution when removing pistonring(s) and C-seal plug seal to avoidscratching any sealing surface.

CAUTION

Do not remove the valve stem from theplug/retainer assembly unless you areplanning to replace the valve stem.

Never reuse an old valve stem with anew plug or reinstall a valve stem after ithas been removed. Replacing a valvestem requires drilling a new pin hole inthe stem. This drilling weakens the stemand may cause failure in service. Howev-er, a used valve plug may be reused witha new valve stem.

2. Remove the plug/retainer assembly (with C-sealplug seal), cage, and seat ring from the valve bodyfollowing the appropriate instructions in the TrimRemoval section of this manual.

3. Locate the staked thread on top of the valve plug(figure 12). The staked thread secures the retainer.Use a drill with a 1/8-inch bit to drill out the staked areaof the thread. Drill approximately 1/8-inch into the met-al to remove the staking.

4. Locate the break between sections of the pistonring(s). Using an appropriate tool such as a flat-bladescrewdriver, carefully pry out the piston ring(s) fromthe groove(s) in the C-seal retainer.

5. After removing the piston ring(s), locate the0.25-inch diameter hole in the groove. In a retainerwith two piston ring grooves, the hole will be found inthe upper groove.

6. Select an appropriate tool such as a punch andplace the tip of the tool into the hole with the body ofthe tool held tangent to the outside diameter of the re-tainer. Strike the tool with a hammer to rotate the re-tainer and free it from the valve plug. Remove the re-tainer from the plug.

7. Use an appropriate tool such as a flat-blade screw-driver to pry the C-seal plug seal off the plug. Use cau-tion to avoid scratches or other damage to the sealingsurfaces where the C-seal plug seal makes contactwith the valve plug (figure 13).

8. Inspect the lower seating surface where the valveplug contacts the seat ring for wear or damage whichwould prevent proper operation of the valve. Also, in-spect the upper seating surface inside the cage wherethe C-seal plug seal contacts the cage, and inspect the

9. Replace or repair trim parts according to the follow-ing procedure for lapping metal seats, remachiningmetal seats, or other valve plug maintenance proce-dures as appropriate.

Lapping Metal Seats (C-sealConstructions)Before installing a new C-seal plug seal, lap the lowerseating surface (valve plug to seat ring, figure 13) fol-lowing appropriate procedures in the Lapping Seatssection of this manual.

Remachining Metal Seats (C-sealConstructions)See figure 14. A valve plug with a C-seal metal plugseal features two seating surfaces. One seating sur-face is found where the valve plug contacts the seatring. The second seating surface is found where the

NOTE:

C-seal plug seal contacts the upper seating surface inthe cage. If you machine the seats on the seat ringand/or plug, you must machine an equal dimensionfrom the seating area in the cage.

CAUTION

If metal is removed from the seat ringand plug and a corresponding amount isnot removed from the cage seating area,the C-seal plug seal will be crushed asthe valve closes and the C-seal retainerwill strike the seating area of the cage,preventing the valve from closing.

Trim Replacement (C-seal Constructions)1. Apply a suitable high-temperature lubricant to theinside diameter of the C-seal plug seal. Also, lubricatethe outside diameter of the valve plug where theC-seal plug seal must be pressed into the proper seal-ing position (figure 9).

2. Orient the C-seal plug seal for correct sealing ac-tion based on the process fluid flow direction throughthe valve.

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

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

Note

An installation tool must be used toproperly position the C-seal plug seal onthe valve plug. A tool is available as aspare part from Fisher Controls or a toolcould be manufactured following the di-mensions given in figure 10.

3. Place the C-seal plug seal over the top of the valveplug and press it onto the plug using the installationtool. Carefully press the C-seal plug seal onto the pluguntil the installation tool contacts the horizontal refer-ence surface of the valve plug (figure 11).

4. Apply a suitable high-temperature lubricant to thethreads on the plug. Then, place the C-seal retaineronto the plug and tighten the retainer using an ap-propriate tool such as a strap wrench.

5. Using an appropriate tool such as a center punch,stake the threads on top of the plug in one place (fig-ure 12) to secure the C-seal retainer.

6. Replace the piston ring(s) following instructions inthe Trim Replacement section of this manual.

7. Return the seat ring, cage, plug/retainer assembly,and stem to the valve body and completely reas-semble the valve package following the appropriateinstructions in the Trim Replacement section of thismanual.

CAUTION

To avoid excessive leakage and seaterosion, the valve plug must be initiallyseated with sufficient force to overcomethe resistance of the C-seal plug sealand contact the seat ring. You can cor-rectly seat the valve plug by using thesame force calculated for full load whensizing your actuator. With no pressuredrop through the valve, this force willadequately drive the valve plug to theseat ring, thus giving the C-seal plugseal a predetermined permanent set.Once this is done, the plug/retainer as-sembly, the cage, and the seat ring be-come a matched set.

With full actuator force applied and thevalve plug fully seated, align the actua-tor travel indicator scale with the lowerend of valve travel. Refer to the appropri-ate actuator instruction manual for in-formation on this procedure.
