WARNING

Personal injury or equipment damagecaused by sudden release of pressuremay result if the valve assembly isinstalled where service conditions couldexceed the limits given in table 1 or onthe appropriate nameplates. To avoidsuch injury or damage, provide a reliefvalve for overpressure protection as re-quired by government or accepted in-dustry codes and good engineeringpractices.

CAUTION

When ordered, the valve configurationand construction materials were se-lected to meet particular pressure, tem-perature, pressure drop, and controlledfluid conditions. Since some body/trimmaterial combinations are limited intheir pressure drop and temperatureranges, do not apply any other condi-

tions to the valve without first contact-ing your Fisher Controls sales office orsales representative.

1. Before installing the valve, inspect it and any asso-ciated equipment for damage and any foreign material.Make certain the valve interior is clean, that pipelinesare free of foreign material, and that the valve is ori-ented so that pipeline flow is in the same direction asthe arrow on the side of the valve.

2. The control valve assembly may be installed in anyorientation unless limited by seismic criteria. However,the normal method is with the actuator vertical abovethe valve. Other positions may result in uneven valveplug and seat ring retainer wear, and improper opera-tion. With some valves, the actuator may also need tobe supported when it is not vertical. For more informa-tion, consult your Fisher Controls sales office or salesrepresentative.

3. Use accepted piping and welding practices wheninstalling the valve in the line. Internal elastomericparts may stay in place during the welding procedure.For flanged valves, use a suitable gasket between thevalve body flange and pipeline flanges.

Note

Depending on valve body materialsused, post weld heat treating may berequired. If so, damage to internal elas-

tomeric and plastic parts, as well as in-ternal metal parts is possible. Shrunk-fitpieces and threaded connections mayalso loosen. In general, if post weld heattreating is to be performed, all trim partsshould be removed. Contact your FisherControls sales office or representativefor additional information.

4. With a leak-off bonnet construction, remove thepipe plugs (key 14, figure 11) to hook up the leak-offpiping. If continuous operation is required during in-spection or maintenance, install a three-valve bypassaround the control valve assembly.

5. If the actuator and valve are shipped separately,refer to the actuator mounting procedure in the ap-propriate actuator instruction manual.

WARNING

Personal injury could result from pack-ing leakage. Valve packing was tight-ened before shipment; however, thepacking might require some readjust-ment to meet specific service condi-tions.

Valves with ENVIRO-SEAL live-loaded packing orHIGH-SEAL� Heavy-Duty live-loaded packing will notrequire this initial re-adjustment. See the FisherControls instruction manuals titled ENVIRO-SEALPacking System for Sliding-Stem Valves or Heavy-Duty Live-Loaded Packing System (as appropriate) forpacking instructions. If you wish to convert your pres-ent packing arrangement to ENVIRO-SEAL packing,refer to the retrofit kits listed in the Parts Kits sub-sec-tion near the end of this manual.

��

Valve 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, trimmaintenance, and ENVIRO-SEAL bellows seal re-placement. All maintenance operations may be per-formed with the valve in the line.

WARNING

Avoid personal injury or property dam-age from sudden release of processpressure or bursting of parts. Before

performing any maintenance opera-tions:

� Disconnect any operating lines pro-viding air pressure, electric power, or acontrol signal to the actuator. Be surethe actuator cannot suddenly open orclose the valve.

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

� Vent the pneumatic actuator load-ing pressure and relieve any actuatorspring precompression.

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

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 since the used gas-ket may not seal properly.

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.

Note

If the valve has ENVIRO-SEAL orHIGH-SEAL live-loaded packing installed,refer to instruction manualsENVIRO-SEAL Packing System for Slid-ing Stem Valves , Form 5306, orHIGH-SEAL Live Loaded Packing System ,Form 5263, for packing instructions. Fig-ure 6 shows a typical HIGH-SEAL packingsystem. Figures 7 and 8 show typical ENVIRO-SEAL systems.

Packing LubricationNote

ENVIRO-SEAL or HIGH-SEAL packingdoes not require lubrication.

If an optional lubricator or lubricator/isolating valve (fig-ure 2) is provided for PTFE/composition or other pack-ings that require lubrication, it will be installed an op-tional tapped hole in the bonnet. Use a good qualitysilicon-base lubricant. Packing used in oxygen serviceor in processes with temperatures over 500�F (260�C)should not be lubricated. To operate the lubricator,simply turn the cap screw clockwise to force the lubri-cant into the packing box. The lubricator/isolatingvalve must first be opened and then closed after lu-brication is completed.

Packing MaintenanceThis section covers PTFE V-ring, PTFE/composition,and graphite/ribbon packing as used in plain and ex-tension bonnets. Unless otherwise indicated, key num-bers refer to figure 3 for PTFE V-ring packing, figure 4for PTFE/composition packing, and figure 5 for graph-ite ribbon/filament packing.

For spring-loaded single PTFE V-ring packing, thespring (key 8, figure 3) maintains a sealing force onthe packing. If leakage is noted around the packingfollower (key 13, figure 3), check to be sure the shoul-der on the packing follower is touching the bonnet. Ifthe shoulder is not touching the bonnet, tighten thepacking flange nuts (key 5, figure 11), until the shoul-der is against the bonnet. If leakage cannot bestopped in this manner, proceed to the ReplacingPacking procedure.

If there is unacceptable packing leakage with otherthan spring-loaded packing, first try to limit the leakageand establish a stem seal by tightening the packingflange nuts.

If the packing is relatively new and tight on the stem,and if tightening the packing flange nuts does not stopthe leakage, the valve stem may be worn or nicked sothat a seal cannot be made. The surface finish of avalve stem is critical for making a good packing seal. Ifthe leakage comes from the outside diameter of thepacking, the leakage may be caused by nicks or

scratches around the packing box wall. If performingany of the following procedures, inspect the valvestem and packing box wall for nicks and scratches.

An illustration of a HIGH-SEAL live-loaded packingsystem is shown in figure 6. Illustrations ofENVIRO-SEAL live-loaded packing systems areshown in figures 7, 8, and 9.

Replacing PackingThis section covers replacing packing used in plainand extension bonnets. PTFE V-ring packing is shownin figure 3, PTFE/composition packing is shown in fig-ure 4, and graphite/ribbon packing is shown in figure 5.

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.If using a power actuator, also shut off all pressurelines to the power actuator, and release all pressurefrom the actuator. Use lock-out procedures to be surethat the above measures stay in effect while you workon the equipment. Observe the warning at the start ofthe Maintenance section.

2. Disconnect the operating lines from the actuatorand any leak-off piping from the bonnet. Disconnectthe stem connector and then remove the actuator fromthe valve by unscrewing the yoke locknut (key 15, fig-ure 11).

WARNING

To avoid personal injury or propertydamage caused by uncontrolled move-ment of the bonnet, loosen the bonnetby following the instructions in the nextstep. Do not remove a stuck bonnet bypulling on it with equipment that canstretch or store energy in any othermanner. The sudden release of storedenergy can cause uncontrolled move-ment of the bonnet. If the seat ring re-tainer sticks to the bonnet, proceedcarefully with bonnet removal.

Note

The following step also provides addi-tional assurance that the valve bodyfluid pressure has been relieved.

3. Hex nuts (key 16, figure 11) attach the bonnet tothe valve. Loosen these nuts or cap screws approxi-mately 1/8 inch (3 mm). Then loosen the body-to-bon-net gasketed joint by either rocking the bonnet or pry-ing between the bonnet and valve body. Work theprying tool around the bonnet until the bonnet loosens.

4. Loosen the packing flange nuts (key 5, figure 11)so that the packing is not tight on the valve stem. Re-move any travel indicator parts and stem locknutsfrom the valve stem threads.

CAUTION

Avoid damaging the seating surfacecaused by the valve plug and stem as-sembly dropping from the bonnet afterbeing lifted part way out. When liftingthe bonnet, temporarily install a valvestem locknut on the valve stem. Thislocknut will prevent the valve plug andstem assembly from dropping out of thebonnet.

8. Remove the packing flange nuts, packing flange,upper wiper, and packing follower (keys 5, 3, 12, and13, figure 11). Carefully push out all the remainingpacking parts from the valve side of the bonnet usinga rounded rod or other tool that will not scratch thepacking box wall. Clean the packing box and the metalpacking parts.

9. Inspect the valve stem threads and the packing boxsurfaces for any sharp edges which might cut thepacking. Scratches or burrs could cause packing boxleakage or damage to the new packing. If the surfacecondition cannot be improved by light sanding, replacethe damaged parts.

10. Remove the covering protecting the valve cavityand install a new bonnet gasket (key 10, figure 12),making sure the gasket seating surfaces are clean andsmooth. Then slide the bonnet over the stem and ontothe stud bolts (key 15, figure 12), or onto the valvecavity if cap screws (not shown) are used instead.

Note

Proper performance of the tighteningprocedures in step 11 compresses thespiral wound gasket (key 12, figure 12)enough to both load and seal the seatring gasket (key 13, figure 12). The tight-ening procedures also compresses theouter edge of the bonnet gasket (key 10,figure 12) enough to seal the body-to-bonnet joint.

The prelubricated stud bolt nuts (key 16,figure 12) referred to in step 11 are iden-tified by a black film coating on the nutthreads.

The accepted bolting procedures re-ferred to in step 11 include—but are notlimited to—ensuring that boltingthreads are clean, and evenly tighteningthe cap screws, or the nuts onto thestuds, in a crisscross pattern. Because

of the boltup characteristics of spiralwound gaskets, tightening one capscrew or nut may loosen an adjacentcap screw or nut. Repeat the crisscrosstightening pattern several times untileach cap screw or nut is tight and thebody-to-bonnet seal is made. When theoperating temperature has beenreached, perform this torquing proce-dure once again.

11. Install bolting, using accepted bolting proceduresduring tightening so that the body-to-bonnet joint canwithstand test pressures and application service condi-tions. The bolt torques in table 2 may be used asguidelines unless accepted bolting procedures dictateotherwise.

12. Install new packing and the metal packing boxparts according to the appropriate arrangement in fig-ure 3, 4, or 5. If split-ring packing is being added, alter-nate the position of the splits to avoid a leak path.Place a smooth-edged pipe over the valve stem andgently tap each soft packing part into the packing box,being sure that air is not trapped between adjacentsoft parts.

Installation of graphite ribbon packing requires specialcare to avoid trapping air between the rings. Start withonly one ring at a time without forcing the top of thepacking ring below the bottom of the entrance chamferof the packing box. Thus, when a ring is added, thestack should not be pushed into the cavity more thanthe thickness of the added ring.

13. Slide the packing follower, upper wiper, and pack-ing flange (keys 13, 12, and 3, figure 11) into position.Lubricate the packing flange studs (key 4, figure 11)and the faces of the packing flange nuts (key 5, figure11). Install the packing flange nuts.

Note

The torque values discussed in step 14and shown in table 3 are recommended

guidelines only and are presented as astarting point for this procedure. Tight-ening the packing flange nuts to atorque value that exceeds the tableguidelines, in order to obtain a seal,may indicate other problems.

14. For spring-loaded PTFE V-ring packing, tightenthe packing flange nuts until the shoulder on the packingfollower (key 13, figure 11) contacts the bonnet.

For graphite packing, tighten the packing flange nuts tothe maximum recommended torque shown in table 3.Then, loosen the packing flange nuts, and retighten themto the recommended minimum torque shown in table 3.

For other packing types, tighten the packing flangenuts alternately in small equal increments until one ofthe nuts reaches the minimum recommended torqueshown in table 3. Then, tighten the remaining flangenuts until the packing flange is level and at a 90-de-gree angle to the valve stem.

For ENVIRO-SEAL or HIGH-SEAL live-loadedpacking, refer to the note at the beginning of theMaintenance section on page 4 of this manual.

15. Mount the actuator on the valve body and recon-nect the actuator and valve stem according to the pro-cedure in the appropriate actuator instruction manual.

Trim MaintenanceThis procedure describes how the valve trim can becompletely disassembled. When inspection or repairsare required, perform only those steps necessary toaccomplish the task. Observe the warning at the startof the Maintenance section.

DisassemblyExcept where indicated, key numbers referenced inthe following steps are found in figure 12.

1. Remove the actuator and the bonnet according tosteps 1 through 6 of the Replacing Packing procedureof the Maintenance section.

CAUTION

To avoid personal injury due to leakingfluids, avoid damaging gasket sealingsurfaces.

The surface finish of the valve stem (key7) is critical for making a good packingseal. The inside surface of the seat ringretainer is critical for smooth operationof the valve plug.

To avoid damaging the ENVIRO-SEALBellows Seal Bonnet assembly, do notattempt to lap the metal seating sur-faces on valves with ENVIRO-SEAL bel-lows seal bonnets. The design of thebonnet assembly prevents rotation ofthe stem and any forced lapping rota-tion will damage internal components ofthe ENVIRO-SEAL Bellows Seal bonnet.

With metal-seat constructions, seating surfaces of thevalve plug and seat ring (key 2, figure 12) can belapped for improved shutoff. (Deep nicks should bemachined out rather than ground out.) Use a goodquality lapping compound of a mixture of 280 to600-grit. Apply the compound to the bottom of thevalve plug.

Assemble the valve to the extent that the seat ringretainer is in place and the bonnet is bolted to thevalve body. A simple handle can be made from apiece of strap iron locked to the valve plug stem withnuts. Rotate the handle alternately in each direction tolap the seats. After lapping, remove the bonnet andclean the seat surfaces. Completely assemble as de-scribed in the assembly portion of the Trim Mainte-nance procedure and test the valve for shutoff. Repeatthe lapping procedure if leakage is still excessive.

AssemblyThis procedure assumes that all the trim and associat-ed gaskets were removed from the valve body. Ifthese parts were not all removed, start the assemblyprocedure at the appropriate step. Except where indi-cated, key numbers referenced in the following stepsare found in figure 12.

Valves with Plain or Extension Bonnets

Perform the following steps to assemble and install thetrim.

CAUTION

To avoid weakening the stem that maycause failure in service, never reuse anold stem with a new valve plug. Usingan old stem with a new plug requiresdrilling a new pin hole in the stem,whichwill weaken the stem. However, a usedvalve plug may be reused with a newstem.

ENVIRO-SEAL Bellows Seal and Bonnet

Replacing a Plain or Extension Bonnetwith an ENVIRO-SEAL Bellows Seal(Stem/Bellows Assembly) and BonnetInstructions are provided for replacing a plain or exten-sion bonnet with an ENVIRO-SEAL bellows seal bon-net when the existing valve has a metal seat. If thevalve has a composition seat, refer to figure 13 and tocomposition seat information in the Valves withENVIRO-SEAL Bellows Seal Bonnet procedure of theTrim Maintenance section.

1. Remove the actuator and bonnet according tosteps 1 through 6 of the Replacing Packing procedureof the Maintenance section.

Note

With some valve plug sizes and configu-rations, the valve plug will slide throughthe seat ring retainer and bushing as-sembly, and in other configurations itwon’t. If the valve plug will not slidethrough the seat ring retainer and bush-ing assembly, then the valve plug andstem assembly and the seat ring retainerand bushing assembly must be removedtogether.

2. Using care, remove the valve plug and stem as-sembly, and, if necessary, the seat ring retainer andbushing assembly from the valve body.

3. Remove and discard the existing bonnet gasket(key 10, figure 12). Cover the valve body opening toprotect sealing surfaces and to prevent foreign materi-al from entering the valve body cavity.

Note

The ENVIRO-SEAL stem/bellows assem-bly for Design E valves is available onlywith a threaded and drilled plug/adaptorconnection. The existing valve plug canbe reused with the new stem/bellows as-sembly or a new plug can be installed.

4. Inspect the existing valve plug. If the plug is ingood condition, it can be reused with the newENVIRO-SEAL stem/bellows assembly. To removethe existing valve plug from the stem, first, place theexisting plug stem assembly in a soft-jaw chuck or oth-er type of vise so that the jaws grip a portion of thevalve plug that is not a seating surface. Drive out ordrill out the pin (key 8, figure 12).

Replacing an Installed ENVIRO-SEALBellows Seal (Stem/Bellows Assembly)Instructions are provided for replacing anENVIRO-SEAL bellows seal (stem/bellows assembly)when the existing valve has a metal seat. If the valvehas a composition seat, refer to figure 13 and to com-position seat information in the Valves withENVIRO-SEAL Bellows Seal Bonnet procedure of theTrim Maintenance section.

1. Remove the actuator and bonnet according tosteps 1 through 5 of the Replacing Packing procedureof the Maintenance section.

Note

With some valve plug sizes and configu-rations, the valve plug will slide throughthe seat ring retainer and bushing assem-bly, and in other configurations it won’t. Ifthe valve plug will not slide through theseat ring retainer and bushing assembly,then the valve plug and stem assemblyand the seat ring retainer and bushingassembly must be removed together.

2. Using care, remove the valve plug and stem as-sembly, and, if necessary, the seat ring retainer andbushing assembly from the valve body. Remove anddiscard the existing bonnet gasket (key 10, figure 12)and gasket (key 22, figure 11). Cover the valve bodyopening to protect sealing surfaces and to prevent for-eign material from entering the valve body cavity.

CAUTION

The ENVIRO-SEAL stem/bellows assem-bly for Design E valves is available onlywith a threaded and pinned adaptor/stem connection. The existing valveplug can be reused with the new stem/bellows assembly or a new plug can beinstalled. If the existing valve plug is re-used, and the adaptor is in good condi-tion, it may be reused also. However, toavoid weakening the adaptor that maycause failure in service, never reuse anold adaptor with a new valve plug. Us-ing an old adaptor with a new plug re-quires drilling a new pin hole in theadaptor, which will weaken the adaptor.However, a used valve plug may be re-used with a new adaptor.

3. Inspect the existing valve plug and adaptor. If they arein good condition, they can be reused with the new stem/bellows assembly, and they do not need to be separated.

CAUTION

When removing/installing a valve plugon the ENVIRO-SEAL stem/bellows as-sembly, the valve stem must not be ro-tated. Damage to the bellows may result.

Do not grip the bellows shroud or otherparts of the stem/bellows assembly.Grip only the flat areas on the stemwhere it extends out of the top of thebellows shroud.

Note

The ENVIRO-SEAL stem/bellows assem-bly has a one-piece stem.

4. If the existing valve plug and adaptor are not ingood condition and must be replaced, first, place theexisting stem/bellows assembly and valve plug andadaptor assembly in a soft-jaw chuck or other type ofvise so that the jaws grip a portion of the valve plugthat is not a seating surface. Drive out or drill out pin(keys 8, figure 12). Drive out pin (key 36, figure 11).

5. Use a wrench on the flat areas on the valve stemjust below the threads for the actuator/stem connec-tion in a soft-jaw chuck or vice to keep the stem fromturning. Then, unscrew the valve plug from the adap-tor and the adaptor from the stem/bellows assembly.

6. To attach either the existing valve plug or a new oneto the stem of the new ENVIRO-SEAL stem/bellows as-sembly, it is necessary to first attach the valve plug tothe adaptor (key 24, figure 11), if the valve plug was re-moved from the adaptor. Locate the adaptor. Notice thata hole has not been drilled in a new adaptor threadswhere the valve plug screws onto the adaptor.

If installing either a new valve plug and/or a new adap-tor, secure the valve plug in a soft-jaw chuck or othertype of vise. Do not grip the plug on any seating surface.Position the plug in the chuck or vise for easy threadingof the adaptor. Thread the adaptor into the valve plugand tighten to the torque values given in figure 10.
