Installation

The valve is normally shipped as part of a control valve assembly, with the power actuator mounted on the valve. If the valve or actuator have been purchased separately, or if the actuator has been removed for maintenance, mount the actuator on the valve, and adjust actuator travel before installing the valve into the line. This is necessary due to the measurements that must be made during the actuator calibration adjustment process. Refer to the Actuator Mounting section of this manual and to the separate actuator instruction manual for mounting and adjusting instructions before proceeding.

WARNING

To avoid personal injury or property damage resulting from the sudden release of pressure:

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

D Do not install the valve assembly where service conditions could exceed

Instruction Manual

Form 5291 March 2008

A31A Valve

the limits given in this manual or on the nameplates.

D Use pressure-relieving devices as required by government or accepted industry codes and good engineering practices to protect from over-pressurizing the system.

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

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

CAUTION

When ordered the valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve materials rests solely with the purchaser and end-user. Since some body/trim material combinations are limited in their pressure drop and temperature range capabilities, do not apply any other conditions to the valve without first contacting your Emerson Process Management sales office.

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

WARNING

See the WARNING at the beginning of the Maintenance section for more information before removing the valve from the pipeline.

2. Install a three-valve bypass around the control valve assembly if continuous operation is necessary during inspection and maintenance of the valve.

3. Inspect the valve to be certain that it is free of foreign material.

CAUTION

Damage to the disc will occur if any pipe flanges or piping connected to the valve interfere with the disc rotation path. If piping flange has a smaller inner diameter than specified for schedule 80 piping, measure carefully to be certain the disc rotates without interference before placing the valve into operation. Minimum inside diameters for flanges or pipe mating with valves are shown in tables 3 and 4.

Be certain that adjacent pipelines are free of any foreign material, such as pipe scale or welding slag, that could damage the valve sealing surfaces.

Valve Orientation

The valve can be installed in any orientation, however, it is recommended that the valve drive shaft be horizontal and the actuator vertical as shown in figure 5.

Install the valve with the high-pressure shutoff side in the direction noted by the flow arrow for proper installation, and see figure 4 for more information.

Before Installing the Valve

WARNING

The edges of a rotating valve disc (key 2, figure 9) close with a shearing, cutting motion. To avoid personal injury, keep hands, tools, and other objects away from the disc while stroking the valve.

If the Type A31A valve is equipped with a fail-open actuator, cycle the valve into the fully closed position. Ensure the valve cannot open during installation by using travel stops, a manual actuator, a constant supply pressure to the pneumatic actuator, or other steps as necessary.

position of the valve disc (key 2). When adjusting the travel stop or travel, make sure that the disc is from 0 to 0.76 mm (0 to 0.030 inch) away from the internal stop in the valve body (see figure 8). This adjustment is necessary to be certain that the actuator output torque is fully absorbed by the actuator travel stop or by the actuator. The internal travel stop in the valve body should not absorb any of the actuator torque.

CAUTION

When using an actuator, the actuator travel stop (or actuator travel, for actuators without adjustable stops) must be adjusted so the disc stop in the valve does not absorb the output of the actuator. Failure to limit the actuator travel as described in the Adjusting the Actuator Travel Stops or Travel steps can result in damage to the valve, shaft(s), or other valve components.

2. Before installing the valve/actuator assembly in the process line, cycle the valve several times to be sure the valve disc returns to the proper position.

Installing the Valve

The maximum allowable inlet pressures for Type A31A valves are consistent with the applicable ASME pressure/temperature ratings except where limited by the material capabilities as shown in table 2 or figure 3.

Refer to table 5 for the quantity and size of line bolting required to install the valve in the pipeline.

CAUTION

To avoid damage to the valve disc during installation, the valve must be in the fully closed position. If the Type A31A valve is equipped with a fail-open actuator, remove the actuator before installing the valve/actuator assembly or cycle the valve into the fully closed position. Then, take appropriate steps to be sure that the actuator does not cause the valve to open during installation.

1. See figure 5 for recommended valve orientation.

D For Wafer-Style Valves: Install the lower flange bolts first to form a cradle for the valve (see figure 4). See table 5 for flange bolt specifications.

Instruction Manual

Form 5291 March 2008

A31A Valve

D For Single-Flange Valves: Position the valve between the flanges. Be sure to leave enough room for the flange gaskets. Install the lower flange bolts.

2. For all Valves: Select the appropriate gaskets for the application. Flat sheet, spiral wound, or other gasket types, made to the ASME B16.5 standard or user’s standard, can be used on Type A31A valves depending on the service conditions of the application.

3. For Wafer-Style Valves: Properly orient the valve according to the specific application. Place the valve in the line so the flow properly enters the valve as indicated by the flow tag. Then, install the valve and the gaskets between the flanges into the cradle formed by the flange bolts.

4. Install the remaining flange bolts.

D For Wafer-Style Valves: Make sure the gaskets are centered on the gasket sealing surfaces of the flange and valve body.

5. For all Valves:Tighten the flange bolts in an alternating criss-cross fashion to a torque value of one-fourth of the final bolting torque. Repeat this procedure several times, increasing the torque value each time by a fourth of the final desired torque. After applying the final torque value, tighten each flange bolt again to allow for gasket compression.

Packing Adjustment and Shaft Bonding

CAUTION

For non-ENVIRO-SEAL packing: Tighten the packing follower nuts only enough to prevent shaft leakage. Excessive tightening will accelerate wear of the packing and could produce higher friction loads on the valve stem.

2. ENVIRO-SEAL Packing Systems: will not require this initial re-adjustment. Refer to the separate instruction manual, ENVIRO-SEAL Packing System for Rotary Valves  Form 5305, for repair and adjustment procedures.

3. For hazardous atmosphere or oxygen service valves, read the following Warning, and provide the bonding strap assembly mentioned below if the valve is used in an explosive atmosphere.

WARNING

The valve shaft is not necessarily grounded when installed in a pipeline unless the shaft is electrically bonded to the valve.

To avoid personal injury or property damage resulting from the effects of a static electricity discharge from valve components in a hazardous atmosphere or where the process fluid is combustible, electrically bond the drive shaft (key 3) to the valve according to the following step.

WARNING

Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing might require some readjustment to meet specific service conditions. Check with your process of safety engineer for any additional measures that must be taken to protect against process media.

1. For PTFE or graphite packing: Tighten standard packing follower nuts only enough to prevent shaft leakage. Excessive tightening of packing will accelerate wear and could produce higher rotating friction loads on the valve stem. If necessary, refer to the Packing Maintenance section.

Note

Standard PTFE packing is composed of a partially conductive carbon-filled PTFE female adaptor with PTFE V-ring packing. Standard graphite packing is composed of all conductive graphite ribbon packing. Alternate shaft-to-valve body bonding is available for hazardous service areas where the standard packing is not sufficient to bond the shaft to the valve (see the following step).

4. Attach the bonding strap assembly (key 131, figure 6) to the shaft with the clamp (key 130, figure 6).

5. Connect the other end of the bonding strap assembly to the valve flange cap screws.

Maintenance

Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions.

Key numbers in this procedure are shown in figure 9 unless otherwise indicated.

WARNING

Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:

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

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure on both sides of the valve. Drain the process media from both sides of the valve.

D Vent the power actuator loading

pressure.

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

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

been removed from the pipeline.

Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when loosening the packing box pipe plug.

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

Removing and Replacing the Actuator

Refer to the appropriate actuator instruction manual for actuator removal and replacement procedures. The actuator stops or travel stops must limit the rotation of the valve shaft. See the CAUTION below.

CAUTION

When using an actuator, the actuator travel stop (or actuator travel stop, for actuators without adjustable stops) must be adjusted so the disc stop in the valve does not absorb the output of the actuator. Failure to limit the actuator travel can result in damage to the valve, shaft(s), or other valve components.

Packing Maintenance

The Type A31A control valve is designed so the packing can be replaced without removing the valve from the process pipeline.

CAUTION

Instruction Manual

Form 5291 March 2008

A31A Valve

Usually, packing leakage can be eliminated by merely tightening the hex nuts (key 15) located above the packing follower (key 12) while the valve is in the pipeline. However, if leakage continues, the packing must be replaced.

For PTFE ENVIRO-SEAL packing system, refer to instruction manual, ENVIRO-SEAL Packing Systems for Rotary Valves  Form 5305 (see figure 10).

CAUTION

Never use a wrench or pliers on the keyed (upper) shaft (key 3). A damaged shaft could cut the packing and allow leakage.

1. Before loosening any parts on the valve, release the pressure from the pipeline. Then, remove the hex nuts (key 15) and lift off the packing follower (key 12).

2. Remove the hex jam nuts (key 17) and the anti-blowout flange (key 10). Remove the packing follower (key 12). Refer to figure 7 for details of the anti-blowout protection parts.

The packing is now accessible.

3. Use a packing extractor to remove packing. Insert the corkscrew-like end of the tool into the first piece of packing and pull firmly to remove the packing. Repeat this process until all packing parts have been removed.

Removing the Valve

1. Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open the valve. Vent the power actuator loading pressure.

2. Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure on both sides of the valve. Drain the process media from either side of the valve.

CAUTION

Damage to the valve disc can occur if the disc is not closed when the valve is being removed from the pipeline. If necessary, stroke the actuator to place the disc in the closed position while removing the valve from the pipeline.

3. Loosen the flange bolting that holds the valve. Make sure the valve cannot slip or twist while loosening and removing the bolting.

4. Before removing the valve from the pipeline, make sure the valve disc is closed. Removing the valve with the disc open could cause damage to the disc, piping, or pipe flanges.

5. After removing the valve from the pipeline, move the valve to an appropriate work area. Always support the valve properly.

6. When valve maintenance is complete, refer to the Installation procedures in this manual.

CAUTION

Be careful when cleaning the packing box. Scratches to the upper shaft (key 3) or inside diameter of the packing bore might cause leakage.

4. Before installing new packing, clean the packing box.

5. Install new packing one ring at a time, using the packing follower as a driver. If using split-ring packing, stagger the splits in the rings to avoid creating a leak path.

6. Reinstall the packing parts. Refer to figure 10 for the sequence of packing parts.

Seal Maintenance

Note

For larger valves, it is possible to replace the seal (key 5) while the actuator is mounted to the valve and can be accomplished by cycling the valve to 90 degrees open.

Key numbers in this procedure are shown in figure 9 unless otherwise indicated.

1. After removing the valve from the pipeline, remove the manual or power actuator. Manually rotate the upper shaft (key 3) counterclockwise until the disc has moved a full 180 degrees away from the closed position.

Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve. Support large valves during maintenance.

2. Lay the valve flat on a work bench in a secure position with the retaining ring (key 18) and retaining ring screws (key 19) facing up. Properly secure the valve on a suitable worktable so it cannot slip, twist, or fall during maintenance. Remove all retaining ring screws.

3. Remove the retaining ring by placing a socket head cap screw from the retaining ring into each of the two retaining ring jacking screw holes. Slowly turn the screws until the retaining ring has been lifted from the valve body. Remove the retaining ring to expose the seal in the T-slot area of the valve body.

Note

The Type A31A is available with different seal designs and components. See figure 3 to identify the specific seal design.

4. Insert a regular screw driver or other similar tool under the top edge of seal and gently pry the seal out of the T-slot area in the valve body. Take care not to damage the seal or T-slot area of the valve body. After the seal has been removed, clean the T-slot area, retaining ring and, if required, polish the disc (key 2) thoroughly with fine steel wool or other appropriate material.

To install a new seal, O-ring (key 6), and retaining ring gasket, follow the appropriate instructions given below.

circumference is one wide groove.

Before installing the seal ring into the valve body, place the O-ring (key 6) into the wide, outer groove of the seal ring. Refer to figure 8.

2. Install the seal ring and O-ring assembly in the valve body. The wider outside diameter of the seal ring, as marked in figure 8, goes into the T-slot area of the body (see figure 5). Start the edge with the wider diameter into the T-slot of the valve body using a blunt-end screwdriver. If you have a maintenance kit, use the seal installation tools.

3. Carefully tuck the O-ring downward into the body T-slot until the seal ring is completely entrapped in the body T-slot, and it completely covers the backup O-ring.

4. Re-install the retaining ring and the socket head cap screws. Tighten the cap screws just enough to eliminate any movement of the retaining ring. Do not over-tighten the retaining ring screws. Using a blunt-end tool, carefully tuck the lip of the seal ring under the retaining ring.

5. When the seal is under the lip of the retaining ring, continue to tighten the cap screws according to standard procedures. Do not fully torque screws at this time. Final tightening of screws is accomplished in step 7 of this procedure.

6. Manually rotate the upper shaft clockwise 180 degrees to return the disc (key 2) to its closed position.

7. The final seating of the retaining ring cap screws can now be done. For the screw torque values, refer to table 6. The seal is now fully installed. Refer to the Installation procedures in this manual.

NOVEX, Phoenix III and/or Phoenix III Fire-Tested Seals

A maintenance kit with installation tools is available through your Emerson Process Management sales office.

Install the seal ring (key 5) in the valve body by first placing the wider outside diameter of the seal ring into the T-slot area of the valve body which is shown in figure 3.

The backup O-ring (key 6) for the Phoenix III seal will have to be installed after placement of the seal ring in the valve body using a blunt-end screwdriver or the seal installation tool in the maintenance kit. Do not use the screwdriver or seal tool directly on the metal seat. Use tools on the O-ring only.

2. With the seal ring inserted all the way around the body T-slot now lay the O-ring into the opening between the valve body and the seal ring. Use the seal tool to apply pressure to the O-ring and carefully tuck the O-ring down into the T-slot between the valve body and the seal ring.

CAUTION

The retaining ring gasket is a thin graphite material. When you punch one initial screw hole through the gasket for alignment, be careful not to cause additional damage to the gasket.

4. Install the retaining ring and align the screw holes in the retaining ring with the holes in the valve body. Install the first retaining ring screw through the punched hole in the ring gasket. Install the other ring screws by pushing the screws through the graphite gasket and threading them into the valve body.

5. Tighten the retaining ring socket head cap screws just enough to eliminate any movement of the retaining ring. Do not over-tighten the retaining ring screws.

WARNING

Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve. Support large valves during maintenance.

6. To complete this step, stand the valve up. Support the valve securely using methods appropriate for the valve size. If a vise or other clamps are being used, be sure to not damage the flange gasket sealing area of the valve body.

7. Manually rotate the upper shaft (key 3) to turn the disc clockwise to meet the seal.

8. Tap the disc with a rubber mallet to drive it against the internal travel stop. When the disc makes contact with the stop, manually rotate the disc counterclockwise back out of the seal to a 90-degree open position. Repeat steps 7 and 8 three times.

Note

On larger valves, it may be more efficient to have someone hold down the seal ring while you push the O-ring into the T-slot.

3. Once the seal ring and backup O-ring have been fully installed into the body T-slot, the retaining ring gasket can be installed. This gasket is a thin graphite material. Punch one initial screw hole through the gasket for alignment, being careful not to cause additional damage to the gasket.

Note

When attaching the actuator to the valve, make sure the valve disc is not in contact with the valve internal travel stop (see figure 8). The valve disc should be positioned from 0 to 0.76 mm (0 to 0.030 inch) away from the internal stop in the valve body (see figure 8).

9. Use an appropriate tool (such as a feeler gauge) to position the disc (key 2) from 0 to 0.76 mm (0 to

0.030 inch) away from the internal stop in the valve body.

Instruction Manual

Form 5291 March 2008

A31A Valve

This adjustment is necessary to be certain that the actuator output torque is fully absorbed by the actuator travel stop or by the actuator. The internal travel stop in the valve body should not absorb any of the actuator torque.

CAUTION

10. The final seating of the retaining ring screws can now be done. For the screw torque values, refer to table 6.

Anti-Blowout Design, Packing, Valve Shaft(s), Disc, and Bearing Maintenance

CAUTION

When removing the actuator from the valve, do not use a hammer or similar tool to drive the lever off the valve shaft. Driving the lever or actuator off the valve shaft could damage the valve internal parts.

If necessary, use a wheel puller to remove the lever or actuator from the valve shaft. It is okay to tap the wheel puller screw lightly to loosen the lever or actuator, but hitting the screw with excessive force could also damage internal valve parts.

Key numbers in this procedure are shown in figure 9 unless otherwise indicated.

1. Remove the valve from the pipeline. Remove the actuator from the valve.

WARNING

Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve. Support large valves during maintenance.

Note

The A31A valve has a two-piece shaft. In these procedures, the drive shaft (with keyed end) is called the upper shaft (key 3). The shaft opposite the upper shaft is called the lower (follower) shaft (key 4).

CAUTION

When using an actuator, the actuator travel stop (or actuator travel adjustment, for actuators without adjustable stops) must be adjusted so the disc stop in the valve does not absorb the output of the actuator. Failure to limit the actuator travel as described in the next step can result in damage to the valve, shaft(s), or other valve components.

CAUTION

Never use a wrench, pliers, or similar tool to turn the upper shaft. A damaged shaft can cut the packing and allow leakage.

Note

It is not necessary to remove the retaining ring and valve seal when removing the shaft(s) and disc.

2. Properly secure the valve on a suitable worktable so it cannot slip, twist, or fall during maintenance.

3. Removing the Anti-Blowout Design:

a. For PTFE or Graphite Packing: Remove the hex nuts (key 15) and pull off the packing follower (key 12). Remove the hex jam nuts (key 17) and the anti-blowout follower (key 10). Remove the anti-blowout gland (key 12). Also, see figure 7.

b. For ENVIRO-SEAL Packing System: Remove the hex nuts (key 101), the packing

A31A Valve

follower (key 102), jam nuts (key 17), anti-blowout flange (key 10), and the spring pack assembly (key 103). See figure 10.

4. Remove the packing from around the upper shaft.

5. Remove the tangential pins or disc pins. Locate the pins (key 25) in the upper shaft (key 3) and the pin in the lower shaft (key 4), if the valve has a two-piece shaft.

a. If a maintenance kit is available, use the pin extractor to remove the disc pins. Select the correct size pin extractor tip with screws of proper thread size to match the thread size in the disc pins. If you do not have a kit, see steps c and d below.

b. Screw the pin extractor tip into the pin as far as possible. With an upward, straight sliding motion, pull out the pin. Repeat the same procedure for the other pins.

c. You can use a threaded rod with an appropriate spacer (tube) and nut as an extractor tool. If you use a threaded rod, choose a rod with threads that fit the inside thread of the pins. The rod should extend several inches above the disc when it is screwed into a pin.

d. After screwing the rod into the pin, slide the spacer over the rod and pin. Thread a nut onto the rod and tighten it. As you tighten the nut, the nut will drive the spacer against the disc. The increasing force will draw the pin from the disc.

6. The gasket retainer (key 20) on the side of the valve opposite the upper shaft must be removed before removing the lower shaft.

CAUTION

To avoid damage to the disc, seal, and T-slot area, do not force the disc past the seal or T-slot area. Remove the disc from the opposite side of the valve body.

Note

Both the upper shaft and the lower shaft have a thrust bearing (key 24) between the disc and the bearings (key

7). The thrust bearing is located outside of the bearing bore which holds the bearings. Use care when removing the valve disc to avoid loss of or damage to the thrust bearings.

9. After removing the shaft(s), remove the disc. Do not force the disc past the seal or T-slot area. Collect the thrust bearings.

10. Remove the bearings (key 7). Using a suitable punch or puller, drive or pull the bearings into the valve body bore from the upper shaft bearing bore. Remove the bearing from the lower shaft bearing bore.

11. Inspect the valve body bore, bearings, bearing bores, and packing box for damage.

Installing the Two-Piece Shaft

Note

Remove the hex head bolts (key 23) and lockwashers (key 22) from the gasket retainer and remove the gasket retainer and gasket (key 21) to expose the end of the lower shaft.

7. Before removing the lower shaft (key 4), be sure the valve disc is properly supported. Pull the lower shaft from the valve body. Use a shaft extractor screwed into the puller hole in the end of the lower shaft.

8. Before removing the upper shaft (key 3), be sure the valve disc is properly supported. Pull out the upper shaft (key 3) by hand-pulling or by using a shaft extractor screwed into the end of the shaft.

In these instructions, the drive shaft (with keyed end) is called the upper shaft (key 3). The shaft opposite the upper shaft is called the lower (follower) shaft (key 4).

Key numbers in this procedure are shown in figure 9 unless otherwise indicated.

1. Properly secure the valve on a suitable worktable so it cannot slip, twist, or fall during maintenance. Be prepared to support the valve disc. Allow for easy access to the valve body bore, drive shaft bearing bore and follower shaft bearing bore.

Form 5291 March 2008

A31A Valve

WARNING

Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve. Support large valves during maintenance.

Note

Replacement disc and shafts are provided as a matched set and both should be replaced at the same time.

2. Inspect all parts removed from the valve for wear or damage. Replace any worn or damaged parts. Clean the valve body and all parts to be installed with an appropriate solvent or degreaser. Note: When installing the bearings, apply lubricant to the outside diameter of the bearing for ease of installation.

CAUTION

Premature valve failure and loss of process control may result if bearings are improperly installed or are damaged during installation.

3. When installing the lower bearings (key 4), insert one or more bearings into the lower shaft bearing bore so it is flush with the body bore.

The number of bearings required changes with valve size and construction. Two bearings are required in the upper shaft and two bearings in the lower shaft. If using an NPS 14 CL150 valve with metal bearings, four bearings in the upper and four in the lower shaft will be required.

4. Hold the lower shaft thrust bearing (key 24) in the valve body bore against the counterbore of the lower shaft bearing bore. Push the lower shaft into the bearing bore just enough to hold the thrust bearing.

5. When installing the upper bearing (key 7), insert one or more bearings into the upper shaft from the body bore into the bearing bore below the packing box. Use caution to prevent damage to the bearing.

CAUTION

Use caution to prevent damage to the bearing when installing the upper bearing in the previous step.

6. Hold the upper shaft thrust bearing (key 24) in the valve body bore against the counterbore of the upper shaft bearing bore. Push the upper shaft through the packing box side into the bearing bore just enough to hold the thrust bearing.

7. When installing the lower bearing (key 4), insert one or more bearings into the lower shaft bearing bore so it is flush with the body bore.

8. Insert the lower shaft through the bore in the valve body uncovered by removal of the gasket retainer. Hold the lower shaft thrust bearing (key 24) in the valve body bore against the counterbore of the lower shaft bearing bore. Push the lower shaft into the bearing bore just enough to hold the thrust bearing.

CAUTION

To avoid damage to the disc, seal, and T-slot area, do not force the disc past the seal or T-slot area. Install the disc from the opposite side of the valve body.

9. Place the flat side of the disc on a flat surface and insert wooden blocks to raise the disc approximately 50.8 mm (2 inches) from the worktable surface. Then, suspend the valve body over the disc so the seal/T-slot area is facing up. Align the shaft bores through the disc with the upper shaft and lower shaft bores. Lower the valve body over the disc using caution not to dislodge or damage the thrust bearings placed on the ends of the shafts.

10. With the disc (key 2) properly positioned in the valve body (key 1), push the upper shaft and lower shaft the rest of the way through the thrust bearings and into the shaft bores in the valve disc.

11. Align the holes in the shafts with the holes in the disc.

CAUTION

To avoid damage to the tangential pins, disc pins, valve disc, or shaft(s) resulting from the application of

A31A Valve

excessive force, use appropriate care when driving the pins into the disc hub and shaft(s). Use the right tool. Do not use excessive force.

12. Install the appropriate tangential pins, and disc pins. Use 2 tangential pins that will go through the upper shaft and 1 disc pin that will go through the lower shaft.

13. Refer to Packing Maintenance and the Anti-Blowout Design procedures in this manual to re-install the packing and anti-blowout design.

Gasket Retainer

Valves with a two-piece shaft use a gasket retainer and gasket (keys 20 and 21) to cover the lower shaft opening in the valve body. The gasket is held in place by the gasket retainer and four hex head bolts and lockwashers (keys 23 and 22). When reassembling the valve, use a new gasket.

Be sure to center the gasket over the lower shaft bore before retightening bolts. Tighten down bolts evenly in a crossover or star pattern.

Refer to table 6 for proper torque values.

serial number is stamped on the nameplate attached to the actuator.

WARNING

Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Process Management should not, under any circumstances, be used in any Fisher valve, because they will void your warranty, might adversely affect the performance of the valve, and could cause personal injury and property damage.

Note

Parts Ordering

When replacement parts are required, always use genuine Fisherr parts.
