Installation

WARNING

Always wear protective gloves, clothing, and eyewear when

performing any installation operations to avoid personal injury.

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

Check with your process or safety engineer for any additional measures

that must be taken to protect against process media.

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

These valves may be installed in many positions by referring to the Actuator Mounting procedures and figure 6 in this manual. For conventional discs, flow may be in either direction. For Fishtail discs, the leading edge of the disc must be located in the upstream end of the valve (see figure 2).

CAUTION

As noted in the following paragraphs, improper use of additional gasketing materials will damage the valve liner.

The valve body liner extends past or overlaps the valve face producing the partial O-ring shown in figure 3. It also acts as the flange gasket. Improper use of additional gasketing materials will damage the valve liner.

Care must be taken during installation to ensure that the pipe flanges are properly supported. Pipe flange support is required to avoid liner flange joint leakage or problems during valve operation. Slip-on pipe flanges may be used with NPS 2, 3, or 4 valves. An NPS 6 valve or larger will require flange adapters for complete liner support.

Mating flanges or pipe flanges with inside diameters smaller than the minimum shown (see table 3) may interfere with the opening of the disc. Flanges or pipes with an inside diameter larger than the maximum shown (see table 3) may not be in full contact with the liner. Install flange adapters in each case, either to provide disc clearance or to fully contact the liner.

Flexible, plastic flanges, fiberglass, slip-on, or weld-neck with other than standard inside diameters may not provide adequate support for the liner. Also, flexible mating flanges can be warped with excessive line bolt load. They may fail to support the liner at the inside diameter of the valve body. Use flange adapters, available from Emerson Process Management, during installation to avoid these problems. Whenever a flange adapter is used, a standard flange gasket must be installed between the line flange and flange adapter. Do not use a

flange gasket between the valve and flange adapter. The partial O-ring on the liner acts as the flange gasket and any additional gasket here will damage the liner.

The Type 9500 valve may be used as part of a three-way valve assembly. The actuator-valve linkage is adjusted at the factory; you won’t need to adjust the linkage before placing the valve in service. If the valve and actuator are being re-installed, after removal, or if you suspect that the linkage is out of adjustment, refer to the Linkage portion of the Adjustments section before installing the valve in the pipeline. If the valve has been purchased separately, or if the actuator has been removed, complete the procedures in the Actuator Mounting section of this manual before proceeding.

WARNING

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

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

DDisconnect 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.

DUse 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.

DVent the power actuator loading pressure and relieve any actuator spring precompression.

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

DThe 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

2. Be certain the pipeline flanges are in line with each other and supported.

CAUTION

To avoid damaging valve seating surfaces, make sure the adjacent piping is free of pipe scale, welding slag, and any other damaging material.

3.Inspect the valve body to be sure it is free of foreign material. Make sure the adjacent piping is free of pipe scale, welding slag, and any other material that could damage valve seating surfaces.

4.Measure to be sure the distance between the pipeline flanges is approximately 1/4 inch greater than the valve face-to-face dimension. This will ensure easy installation without distorting the liner (figure 3).

5.For conventional discs, flow may be in either direction; for Fishtail discs, flow must be such that the tail of the disc (as shown in figure 2) will rotate into the downstream side of the valve.

CAUTION

To avoid damaging valve parts, observe the following precautions before inserting the valve in the line.

a.The inside diameter of the mating piping or flanges must be large enough to allow the valve disc to rotate freely into the upstream and downstream piping, or the disc could be damaged. Do not use piping or flanges having an inside diameter smaller than the minimum shown in table 3.

b.The inside of the mating flange must also be small enough to be in full contact with the partial O-rings on the liner faces. Leakage through the flange connections and damage to the liner could

4

Instruction Manual

Form 2433

November 2007

9500 Valve

result if the partial O-ring faces are not properly supported. Do not use flanges having an inside diameter larger than the maximum shown in table 3.

The NPS 6 to 10 sizes must not be used with slip-on flanges unless flange adaptors are used to support the liner. When using slip-on flanges with other sizes, be certain the valve is carefully centered to ensure that the partial O-ring faces are in full contact with the adjacent flanges.

c.When a flange adapter is necessary, a flange gasket must be installed between the line flange and the flange adapter. Do not use a flange gasket between the valve and the flange adapter. Additional gasketing material at this location could damage the liner.

d.The valve disc must be in the closed position when the valve is being inserted into the pipeline. If the valve disc is not closed, it could be damaged against the mating piping or flanges.

6.Insert the valve into the pipeline. Insert four flange studs or bolts through the flanges to support the valve.

7.Center the valve carefully on the flanges by measuring equal distances at the top and bottom and equal distances at the sides.

8.Insert the remaining flange studs or bolts. Tighten the studs or bolts evenly. Normal flange bolt torques may be used because liner compression is limited by metal-to-metal contact between flanges and the valve body.

9.Rotate the valve disc manually to be certain the disc clears the adjacent piping or flanges as it opens. If necessary, disconnect the power actuator-valve linkage, but do not disturb the adjustment of the turnbuckle or adjustable linkage. If the disc hits the flange, loosen flange bolting temporarily while re-centering the valve. If the problem cannot be corrected in this manner, it will be necessary to use line flanges with larger inside diameters adjacent to the valve.

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

37A6528

Figure 4. Grounding Assembly

WARNING

The valve drive shaft is not necessarily grounded to the pipeline when installed. Personal injury or property damage could result, if the process fluid or the atmosphere around the valve is flammable, from an explosion caused by a discharge of static electricity from the valve components. If the valve is installed in a hazardous area, electrically bond the drive shaft to the valve.

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

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

Adjustments

Hub Seals

Key number locations are shown in figure 7.

Thrust sleeve assemblies (key 6) seal the disc hubs. In time, especially with frequent valve disc rotation, these seals may require adjustment.

Adjust the seals if there is leakage through the valve body around the valve shaft. A small amount of

5

9500 Valve

Instruction Manual

Form 2433

November 2007

leakage downstream (between the bushings and disc hubs) may also indicate a need for hub seal adjustment.

To adjust the hub seals:

1. Tighten both thrust-plate cap screws (key 10) 1/4 turn on one side (the side where shaft leakage is occurring).

To check the linkage adjustment on Fishtail discs, the flat is on the same side of the shaft as the nose or leading edge of the valve disc (as shown in figure 2). When the valve disc is at the fully closed position, the flat will be either top-dead-center or bottom-dead-center in relation to the valve body. The top-dead-center position is shown in figure 2. A more accurate check of the fully closed disc position is obtained by removing the valve from the pipeline.

CAUTION

To avoid excessive side thrust on the disc and possible liner damage, tighten cap screws on both sides of the valve alternately and in 1/4-turn increments. Do not over-tighten by continuous turning or by tightening one side only. Overtightening the cap screws will cause the liner to fail.

2.Tighten both thrust-plate cap screws 1/4 turn on the other side of the valve.

3.Repeat steps 1 and 2 until leakage stops.

Note

If this adjustment is being performed to stop minor leakage past the disc, check the leakage after turning the cap screws enough to move the thrust plates 0.8 mm (1/32 inch) closer to the valve body. If leakage has not stopped or diminished, the leakage is probably due to incorrect linkage adjustment or damaged valve parts. Refer to the Linkage section to check linkage adjustment; refer to the Maintenance section to inspect and replace parts.

4. If leakage around the shaft cannot be stopped by adjusting hub seals, refer to the Maintenance section to inspect and replace damaged parts.

Linkage

If the linkage between the power actuator and valve is improperly adjusted, the actuator may reach the end of travel before (or after) the disc reaches the fully closed position. This could result in leakage past the disc. The linkage adjustment is set at the factory, and it should not be necessary to adjust linkage unless the actuator and valve have been separated and the adjustment altered.

WARNING

To avoid personal injury and damage to the process system caused by the sudden release of pressure, isolate the control valve from all pressure and relieve pressure from the valve body before removing the valve from the line. Be sure the disc is closed so that it will not hit the mating flanges when being removed from the line.

With the valve removed from the line, position the actuator to the valve-closed end of the travel. Measure the distance between the valve face and the top and bottom edges of the disc as shown in figure 2. The disc is at the fully closed position if the two measurements are equal.

To adjust linkage, refer to the actuator instruction manual.

Three-Way Valve Tandem Linkage

If the valve is used as part of a three-way valve assembly, adjustment of the tandem linkage (see figure 5) may be necessary to ensure proper rotation of the slave valve disc.

If the adjustment is being performed with the three-way valve assembly out of the line, temporarily bolt the valve bodies to the tee to compress the liner faces until there is metal-to-metal contact between the valve bodies and the tee.

Check the rotation of the power valve disc per instructions in the Linkage section. If necessary, adjust the linkage between the actuator and the power valve.

To check the fully closed position of the slave valve disc, use the partial keyway on the slave valve shaft or measure equal distances between the slave valve face and the top and bottom of the slave valve disc as described in the Linkage section. Tighten the

locknuts on the tandem linkage when adjustment is complete.

Maintenance

Use table 4 to locate and correct possible leakage or mechanical linkage problems with the valve.

WARNING

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

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

DDisconnect 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.

DUse 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.

DVent the power actuator loading pressure and relieve any actuator spring precompression.

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

DThe 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.

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

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.

Disassembly

Key numbers locations are shown in figure 7.

1. Loosen all flange studs or bolts. Remove all but the bottom flange studs or bolts.

CAUTION

To avoid damage to the valve disc caused by the disc hitting the mating flange, be certain the disc is closed before removing the valve from the pipeline.

2.If necessary, pry flanges apart so that liner faces will not be damaged when the valve is being removed. Inspect the disc (key 3) and liner (key 2) for wear or damage.

3.Remove the actuator from the valve. Follow instructions in the appropriate actuator instruction manual.

4.From both sides of valve, unscrew thrust-plate cap screws (key 10) and remove thrust plates (key 9).

Reassembly

Before reassembling the valve, clean and inspect all parts. Key number locations are shown if figure 7. Refer to the Parts List section to obtain replacement parts.

c.Insert the liner into the valve body. Align the liner shaft holes with valve body shaft holes. Remove excess bonding agent from shaft holes and exposed liner surfaces.

d.Insert the disc (key 3), thrust sleeve assemblies (key 6), and shaft (key 4) into the valve body. Be sure the thrust sleeve assemblies engage the liner recesses to ensure proper liner positioning. Rotate the disc to the closed position.

e.Lay the valve on one valve face and add weights to the other face to ensure a tight bond. Allow to cure for 24 hours. Then, proceed with the following reassembly steps.

2.Insert the thrust sleeve assemblies into the valve body. Be sure that the thrust sleeve assemblies enter the liner recesses to align the shaft holes, by temporarily inserting the shaft(s) (key 4).

WARNING

Do not lubricate parts when used in oxygen service, or where the lubrication is incompatible with the process media. Any use of lubricant can lead to the sudden explosion of media due to the oil/oxygen mixture, causing personal injury or property damage.

1. Insert the liner (key 2) into the valve body. A small amount of silicone grease applied to the outside surface of the liner will aid insertion of the liner. However, do not use grease if the valve is to be used for oxygen service.

In vacuum service applications, upon customer request, you may use Eccobondr 285/24LV bonding agent (Fisherr part no. G1414006992) to bond the liner to the valve. Though bonding is not required use the lettered steps below when bonding the liner to the valve body. If a different agent is to be used, follow instructions furnished by the bonding agent manufacturer. In absence of instructions, consult your Emerson Process Management sales office.

a.Roughen bonding surface of liner with a stiff wire brush. De-grease bonding surfaces of the liner and valve body with solvent.

b.Mix the two epoxy components thoroughly and spread a thin coat [approximately 0.38 mm (0.015 inches) thick] of the mixture over all bonding surfaces of the valve body and liner.

3. A new disc and shaft should be installed if the taper pin holes have been widened by loosening of the taper pins (key 15).

Omit the following steps 4 through 8 if a new disc and shaft assembly is to be installed or if the old disc and shaft are to be reused. Use new taper pins whenever the disc has been removed.

CAUTION

If a new disc is required, a complete disc/shaft assembly must be purchased to avoid damage to valve parts. The old valve shaft cannot be used with a new disc.

If a new shaft (without disc) has been purchased, be sure to mark the shaft to indicate the disc position as shown in figure 2.

4.Making certain the taper pin holes are on the actuator side of the valve body, insert the disc into the valve body. Position the disc at the fully closed position.

5.Installing splined shaft:

a. If the old shaft is available, insert it into the valve body and disc. Line up the taper pin holes in the disc and shaft; measure and record the distance between the valve body and the splined end of the shaft. Remove the old shaft and insert the new, un-drilled shaft. Position the shaft so that there is the same distance between the valve body and the end of the shaft as noted above.

b. If installing a new shaft, insert the new shaft into the valve body and disc. Measure between the valve body and the splined end of the shaft. Make certain that the distance is correct to engage the actuator coupling lever.

Be certain that the flat spot or index mark on the end of the shaft is positioned as shown in figure 2.

6.Use a drill or center punch to mark the taper pin holes in the shaft. Remove the shaft and disc from the valve body.

7.Taper pins used in Type 9500 valve shaft and disc are American Standard taper pins as shown in table 5. Using the disc as a guide, drill taper pin holes through the shaft using drill size shown in table 5.

8.Use an American Standard taper pin reamer to ream the shaft holes. Be certain the reamer is of sufficient length for the disc hub thickness. Insert the shaft into the disc when reaming so the disc holes can be used as a gauge for reaming. Allow the reamer to just begin reaming the disc holes. This will ensure proper seating of the pins.

9.Install the disc and shaft into the valve body. Be sure the splined end of the shaft is on the actuator side of the valve body, that the direction of taper in the taper pin holes match, and that the flat spot or zero mark is positioned as shown in figure 2.

10.Using a metal sealing compound on the pins for a positive seal, insert the taper pins into the larger end of the taper pin holes. Drive the pins with a hammer to seat the pins.

11.Attach the thrust plates (key 9) with cap screws (key 10). When tightening the cap screws, do so in small increments, alternating from one cap screw to another and from one valve side to the other.

Tighten the cap screws until the thrust plates contact the thrust sleeve assemblies snugly. Then rotate the cap screws enough to move the thrust plates 0.8 mm (1/32 inch) closer to the valve body.

12.Re-attach the actuator according to the steps in the Actuator Mounting section; then install the valve according to the steps in the Installation section.

Actuator Mounting

1. Refer to the appropriate actuator instruction manual to determine the desired actuator mounting style and position. With the valve out of the line, mount the actuator on the valve per instructions in the actuator instruction manual.

2.To determine the fully closed disc position, measure the distances between the valve face and the top and bottom edges of the disc as shown in figure 2. The disc is at the fully closed position when the two measurements are equal. Rotate the disc slightly if necessary to make the measurements equal.

3.Refer to figure 6 and locate the view that depicts the mounting style and position that is being used. In the appropriate view on the right of figure 6, note the positions of the index marks on the end of the valve shaft and actuator lever. For all positions and styles with 90-degree disc rotation, the shaft index mark is to be aligned with the appropriate lever index mark as shown in figure 6. This is also true for push-down-to-open action with 60-degree maximum disc rotation. However, for push-down-to-close action with 60-degree maximum disc rotation, the appropriate lever index mark must be offset one or two spline teeth counterclockwise from the shaft index mark.

Refer to the appropriate actuator instruction manual for instructions covering attaching the lever and adjusting the turnbuckle. For Fishtail discs, be certain that the direction of rotation will be such that the tail of the disc (see figure 2) will rotate into the downstream side of the valve.

Changing Disc Rotation and

Action

Disc rotation can be changed from 0-90 degrees or vice versa by changing travel stops in the actuator and, if necessary, changing the position of the lever on the splined valve shaft. Action can be changed from push-down-to-open to push-down-to-close by removing the actuator and remounting it in the alternate mounting style. Refer to the appropriate actuator instruction manual for assistance in disassembly and reassembly to change travel stops and for instructions to change mounting style.

Note

Action for valves using a splined valve shaft can also be changed, without changing mounting style, by repositioning the actuator lever on the valve shaft. For Fishtail discs, it will be necessary to rotate the disc 180 degrees so that the tail of the disc will rotate into the downstream side of the valve.

Use the following procedure.

1.Refer to the appropriate actuator instruction manual for assistance in disconnecting and removing the actuator lever. Avoid disturbing the actuator turnbuckle adjustment, if possible.

2.If the valve disc is a Fishtail disc, rotate the disc

180degrees from the original position.

3.Position the disc in its fully closed position. To ensure that disc is fully closed, measure equal distances between valve face and top and bottom of the disc as shown in figure 2 or check to be sure that the flat spot or index mark on the valve shaft is in top-dead-center or bottom-dead-center in relation to the valve.

WARNING

To avoid personal injury, keep hands away from the actuator rod in the following procedure.

4. Note the position of the valve shaft index mark. Index mark alignments for reversed action are not shown in figure 6. To determine proper index mark alignment, proceed as follows:

a.Stroke the actuator to the valve-closed end of travel and retain that position while performing the next step.

b.Keeping hands away from the actuator rod, hold the actuator lever up to the valve shaft so that the lever end is in line with the actuator rod end bearing. The lever index mark that is most nearly in line with the valve shaft index mark is the index mark that must be used during reassembly. If changing to push-down-to-close action with 60-degree operation, the lever index mark will be offset 1 spline tooth from the valve shaft index mark for 12.7 through 19.1 mm (1/2 through 3/4-inch) valve shafts and 2 spline teeth from the valve shaft index mark for 25.4 and 31.8

mm(1 and 1-1/4 inch) valve shafts. This offset must be maintained during reassembly.

5.Record the alignment determined in step 4, remove the actuator lever, and shut off operating pressure to actuator.

6.Reassemble the lever to the actuator and adjust the actuator travel, if necessary, referring to the steps in the appropriate actuator instruction manual. Be sure to use the index mark alignment determined above rather than those shown in figure 6.

Parts Ordering

A serial number is assigned to each valve body and stamped on the nameplate. Always refer to the serial number when corresponding with your Emerson Process Management sales office regarding spare parts or technical information. When ordering replacement parts, also specify the complete 11-character part number from the parts list information.

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 give rise to personal injury and property damage.

Note

Neither Emerson, Emerson Process Management, nor any of their affiliated entities assumes responsibility for the selection, use and maintenance of any product. Responsibility for the selection, use, and maintenance of any product remains with the purchaser and end-user.
