Introduction
Scope of Manual
This manual provides installation, adjustment, and maintenance information for Fisher 9500 butterfly valves. These
valves use splined shafts with actuator‐mounted brackets and linear‐motion actuators (see figure 1). Refer to separate
manuals for instructions covering the power actuator or the manual handwheel actuator, positioner, and other
accessories.
Do not install, operate, or maintain 9500 valves without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to
carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you
have any questions about these instructions, contact your Emerson sales office before proceeding.
Description
The 9500 valve is a fully lined butterfly valve for use with corrosive process fluids or wherever stringent shutoff is
required. The nitrile or PTFE liner completely isolates the valve body and shaft from the process fluid. The valve is
available with conventional or FISHTAIL™disk designs.

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 disks, flow may be in either direction. For FISHTAIL disks, the leading edge of the disk 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 disk. 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 disk 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 Automation
Solutions, 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 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:
D Do not remove the actuator from the valve while the valve is still pressurized.
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 and relieve any actuator spring precompression.
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.

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 continuous operation is required during inspection or maintenance,
install a three‐valve bypass around the control valve assembly.
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 disks, flow may be in either direction; for FISHTAIL disks, flow must be such that the tail of the disk
(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 disk to rotate freely
into the upstream and downstream piping, or the disk 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 result if the partial O‐ring

Instruction Manual
D100380X012
9500 Valve

6
faces are not properly supported. Do not use flanges having an inside diameter larger than the maximum shown
in table 3.
NPS 6 to 10 valves 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 disk must be in the closed position when the valve is being inserted into the pipeline. If the valve disk 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 disk manually to be certain the disk 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 disk 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.
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 disk hubs. In time, especially with frequent valve disk 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 leakage
downstream (between the bushings and disk hubs) may also indicate a need for hub seal adjustment.

ACTUATOR END PLATE
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).
CAUTION
To avoid excessive side thrust on the disk 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. Over‐
tightening 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 disk, 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 disk reaches the fully closed position. This could result in leakage past the disk. 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.
To check the linkage adjustment on FISHTAIL disks, the flat is on the same side of the shaft as the nose or leading edge
of the valve disk (as shown in figure 2). When the valve disk 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 disk position is obtained by removing the valve from the pipeline.
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 disk 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 disk as shown in figure 2. The disk 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 disk.

Instruction Manual
D100380X012
9500 Valve

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 disk 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 disk, 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 disk 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:
D Do not remove the actuator from the valve while the valve is still pressurized.
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 and relieve any actuator spring precompression.
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.
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 disk caused by the disk hitting the mating flange, be certain the disk is closed before
removing the valve from the pipeline.

Table 4. Troubleshooting Guide
Fault Possible Cause Correction
1. Leakage out sides of
valve (at thrust plates)
between thrust bushings
and shaft.
a. Hub seals require adjustment.
b. Taper pins are not sealed.
a. Adjust using Hub Seals portion of Adjustments
procedures.
b. Remove valve from line and re‐seat taper pins or install
new taper pins using Maintenance procedures.
2. Leakage out sides of
valve (at thrust plates)
between valve body and
thrust bushings, leakage at
flanges, faces, or both
a. Flange gaskets used.
b. Partial O‐ring bead on liner faces damaged.
a. Check to see if flange gaskets are being used; if so, remove
gaskets.
b. Replace liner using Maintenance procedures.
3. Leakage through
disk/liner seal
a. Hub seals require adjustment.
b. Linkage requires adjustment.
c. Actuator has insufficient torque output to close disk
against pressure drop. (Actuators are selected to have
sufficient torque output to shut off the flow against a specific
pressure drop, not necessarily against the maximum
allowable pressure drop. Be sure that the pressure drop for
which the actuator is selected is not being exceeded.)
d. Liner has been damaged by flowing medium or other valve
parts damaged by being subjected to service conditions
beyond those for which valve is designed.
a. Adjust seals using Hub Seals portion of Adjustments
procedures.
b. Refer to Linkage portion of Adjustments procedures.
c. If possible, check shutoff at lower pressure drops. If shutoff
is obtained at low pressure drops, but actuator stalls and
does not produce full disk rotation at service pressure drop,
actuator output torque is too low. For piston actuators, it
may be possible to increase output torque by increasing
supply pressure. Do not exceed maximum allowable supply
pressure of actuator.
d. Inspect and replace parts using Maintenance procedures.
4. Valve shaft will not
rotate
a. If actuator does not stall, but shaft does not rotate, the
spline teeth on the valve shaft are sheared.
b. If actuator stalls, shaft is binding in bushings due to
linkage misalignment caused by excessive wear of linkage
parts.
c. If actuator stalls and linkage is not misaligned, actuator
may have insufficient output torque to rotate disk against
flow.
a. Refer to the actuator instruction manual to remove
actuator cover plate. Replace valve shaft using Maintenance
procedures if spline teeth are sheared.
b. Replace linkage parts.
c. Check actuator operation with no pressure applied to the
valve. If valve now functions properly, actuator is too small.
5. Valve shaft rotates, but
valve does not control
process fluid
Taper pins (or drive shaft spline for coated‐disk
constructions) have been sheared due to obstruction to disk
rotation or other internal parts damaged by being subjected
to service conditions beyond those for which the valve was
designed.
Inspect and replace parts using the Maintenance procedures.
2. If necessary, pry flanges apart so that liner faces will not be damaged when the valve is being removed. Inspect the
disk (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).
5. If taper pin (key 15) ends are peened, grind off the peened portions. Driving from the smaller end of the pins, drive
the pins out of the disk (key 3) and shaft (key 4).
WARNING
Once the shaft has been removed, the disk may fall from the valve body, causing personal injury or disk damage. Support
the disk before removing the shaft.
6. Pull the shaft out of the valve body. If the shaft cannot be pulled from the valve body, drive the shaft out but use
care to avoid upsetting the end of the shaft.
7. Remove the disk from the valve body.

8. Remove the liner (key 2) from the valve body.
Some 9500 valves have the liner bonded to the valve body. If the valve has a bonded liner, burn or chip out the liner.
To strip the liner out with solvent, use Dynasolve 185, or equivalent solvent. (Dynasolve is a product of DYNALOYt
Inc.). Cover the valve with solvent bath or enclose the solvent bath around the liner. Remove all adhesive after the liner
has been removed.

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.
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 Eccobondr285/24LV bonding agent (Fisher part
number 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 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.
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 disk (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 disk 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).

3. A new disk 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 disk and shaft assembly is to be installed or if the old disk and shaft are to
be reused. Use new taper pins whenever the disk has been removed.
CAUTION
If a new disk is required, a complete disk/shaft assembly must be purchased to avoid damage to valve parts. The old valve
shaft cannot be used with a new disk.
If a new shaft (without disk) has been purchased, be sure to mark the shaft to indicate the disk position as shown in
figure 2.
4. Making certain the taper pin holes are on the actuator side of the valve body, insert the disk into the valve body.
Position the disk at the fully closed position.
5. Installing splined shaft:
a. If the old shaft is available, insert it into the valve body and disk. Line up the taper pin holes in the disk 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 disk. 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 disk from the valve body.
7. Taper pins used in the 9500 valve shaft and disk are American Standard taper pins, as shown in table 5. Using the
disk 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 disk hub thickness. Insert the shaft into the disk when reaming so the disk holes can be used as a gauge for
reaming. Allow the reamer to just begin reaming the disk holes. This will ensure proper seating of the pins.
9. Install the disk 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 disk position, measure the distances between the valve face and the top and bottom
edges of the disk as shown in figure 2. The disk is at the fully closed position when the two measurements are equal.
Rotate the disk 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 disk 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 disk rotation. However, for push‐down‐to‐close action with 60‐degree maximum disk
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 disks, be certain that the direction of rotation will be such that the tail of the disk (see figure
2) will rotate into the downstream side of the valve.

Changing Disk Rotation and Action
Disk 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 disks, it will be necessary to rotate the disk 180 degrees so that the tail of the disk 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 disk is a FISHTAIL disk, rotate the disk 180 degrees from the original position.
3. Position the disk in its fully closed position. To ensure that disk is fully closed, measure equal distances between
valve face and top and bottom of the disk 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.
