Introduction
Scope of Manual
This manual provides installation, adjustment, and
maintenance information for Fisher Type 9500 butter-
fly valves. These valves use splined shafts with actua-
tor-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.
Only personnel qualified through training or experience
should install, operate, and maintain this valve. If you
have any questions about these instructions, contact
your Fisher Controls sales office or sales representa-
tive before proceeding.

Description
The Type 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
FishtailRdisk designs.
Installation
These valves may be installed in many positions by
referring to the Actuator Mounting procedures and fig-
ure 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).
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 2, 3, or 4-inch valves. A 6-inch valve
or larger will require flange adapters for complete liner
support.
Mating flanges or pipe flanges with inside diameters
smaller than the minimum shown may interfere with
the opening of the disk. Flanges or pipes with an in-
side diameter larger than the maximum shown may
not be in full contact with the liner. Install flange adapt-
ers 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, flex-
ible mating flanges can be warped with excessive line
bolt load. They may fail to support the liner at the in-
side diameter of the valve body. Use flange adapters,
available from Fisher Controls, during installation to
avoid these problems. Whenever a flange adapter is
used, a standard flange gasket must be installed be-
tween 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 gas-
ket 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 ad-
justed at the factory; you won’t need to adjust the link-

Type 9500

age 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 be-
fore 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 re-
lease of process pressure. Before per-
forming any maintenance operations:
DDisconnect any operating lines pro-
viding 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.
1. Isolate the control valve from the line pressure, re-
lease 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.
3. Inspect the valve body to be sure it is free of for-
eign 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 pipe-
line 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 direc-
tion; 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 insert-
ing 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 down-
stream piping, or the disk could be damaged.
b. The inside of the mating flange must also be
small enough to be in full contact with the partial

Type 9500
4
O-rings on the liner faces. Leakage through the
flange connections and damage to the liner could
result if the partial O-ring faces are not properly
supported.
The 6 to 10-inch 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 adpater 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. Addition-
al 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 mea-
suring 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 link-
age, but do not disturb the adjustment of the turn-
buckle 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 man-
ner, 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
bonding strap assembly mentioned below 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 flam-
mable, from an explosion caused by a
Figure 4. Grounding Assembly
37A6528-A/DOC
discharge of static electricity from the
valve components. If the valve is
installed in a hazardous area, electrical-
ly bond the drive shaft to the valve.
Note
The packing is composed of all conduc-
tive packing rings (graphite ribbon
packing) or partially conductive packing
rings (carbon-filled PTFE female adaptor
with PTFE V-ring packing or graphite-
composition packing ring with PTFE/
composition packing) to electrically
bond the shaft to the valve for hazard-
ous area service. For oxygen service ap-
plications, provide alternate shaft-to-
valve body bonding according to the
following step.
11. Attach the bonding strap assembly (key 131, fig-
ure 4) to the shaft with the clamp (key 130, figure 4).
12. Connect the other end of the bonding strap as-
sembly 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.

Type 9500
5
Adjust the seals if there is leakage through the valve
body around the valve shaft. A small amount of leak-
age downstream (between the bushings and disk
hubs) may also indicate a need for hub seal adjust-
ment.
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 oc-
curring).
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 turn-
ing 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 1/32
inch (0.8 mm) 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 re-
place 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 ad-
justment 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-cen-
ter 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 sud-
den release of pressure, isolate the con-
trol valve from all pressure and relieve
pressure from the valve body before re-
moving 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 ac-
tuator 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 measure-
ments 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 as-
sembly, adjustment of the tandem linkage (see figure
5) may be necessary to ensure proper rotation of the
slave valve disk.
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 instruc-
tions 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 de-
scribed in the Linkage section. Tighten locknuts on
tandem linkage when adjustment is complete.

Maintenance
Valve parts are subject to normal wear and must be
periodically inspected and replaced as necessary. The
frequency of parts inspection and replacement de-
pends upon the severity of service conditions. Due to
the care Fisher Controls takes in meeting all manufac-
turing requirements (heat treating, dimensional toler-
ances, etc.), use only replacement parts manufactured
or furnished by Fisher Controls. Instructions are given
below for complete disassembly and reassembly of
the valve.
Use Table 3 Troubleshooting Guide to locate and cor-
rect possible leakage or mechanical linkage problems
with the valve.
WARNING
Avoid personal injury from sudden re-
lease of process pressure. Before per-
forming any maintenance operations:
DDisconnect any operating lines pro-
viding 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.
1. Isolate the control valve from the line pressure, re-
lease 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 be-
fore removing the valve from the pipe-
line.
2. If necessary, pry flanges apart so that liner faces
will not be damaged when valve is being removed.
Inspect the disk (key 3) and liner (key 2) for wear or
damage.
3. Remove actuator from the valve. Follow instruc-
tions 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
peened portions. Driving from smaller end of pins,
drive pins out of disk (key 3) and shaft (key 4).
CAUTION
Once the shaft has been removed, the
disk may fall from the valve body, caus-
ing personal injury or disk damage.
Support the disk before removing the
shaft.
6. Pull 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.

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

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, bur
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.
7. Remove disk from valve body.
8. Remove liner (key 2) from valve body.
Some Type 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 Eccostrip 57,
Houghto Clean 224, or equivalent solvent. 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.
1. Insert liner (key 2) into 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 re-
quest, you may use Eccobond 285/24LV bonding
agent (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 ab-
sence of instructions, consult your Fisher Controls
sales office or sales representative.
a. Roughen bonding surface of liner with a stiff
wire brush. De-grease bonding surfaces of liner
and valve body with solvent.
b. Mix the two epoxy components thoroughly and
spread a thin coat [approximately 0.015 inches

Type 9500
8
(0.38 mm) thick] of the mixture over all bonding
surfaces of the valve body and liner.
c. Insert the liner into valve body. Align the liner
shaft holes with valve body shaft holes. Remove
excess bonding agent from shaft holes and ex-
posed liner surfaces.
d. Insert disk (key 3), thrust sleeve assemblies
(key 6), and shaft (key 4) into the valve body. Be
sure thrust sleeve assemblies engage the liner re-
cesses to ensure proper liner positioning. Rotate
disk to 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 thrust sleeve assemblies into valve body. Be
sure that the thrust sleeve assemblies enter the liner
recesses to align the shaft holes, by temporarily insert-
ing 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 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.
If a new shaft (without disk) has been purchased, be
sure to mark the shaft to indicate disk position as
shown in figure 2.
4. Making certain the taper pin holes are on the ac-
tuator side of the valve body, insert the disk into the
valve body. Position the disk at the fully closed posi-
tion.
5. Installing splined shaft:
f. 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 dis-
tance 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 end of the shaft as was noted above.
g. If installing a new shaft, insert the new shaft
into valve body and disk. Measure between the
valve body and the splined end of the shaft. Make
certain that distance is correct to engage the actua-
tor 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 shaft and disk from valve
body.
7. Taper pins used in Type 9500 valve shaft and disk
are American Standard taper pins as shown in table 4.
Using disk as a guide, drill taper pin holes through the
shaft using drill size shown in table 4.
8. Use an American Standard taper pin reamer to
ream the shaft holes. Be certain the reamer is of suffi-
cient length for the disk hub thickness. Insert the shaft
into the disk when reaming. In this way, 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 disk and shaft into 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 taper pins into the larger end of the
taper pin holes. Drive pins with a hammer to seat pins.
11. Attach thrust plates (key 9) with cap screws (key
10). When tightening cap screws, do so in small incre-
ments, alternating from one cap screw to another and
from one valve side to the other. Tighten cap screws
until thrust plates contact the thrust sleeve assemblies
snugly. Then rotate the cap screws enough to move
the thrust plates 1/32 inch (0.8 mm) 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.

Type 9500

Actuator Mounting
1. Refer to the appropriate actuator instruction manu-
al to determine the desired actuator mounting style
and position. With the valve out of the line, mount the
actuator on the valve per instruction in the actuator
instruction manual.
2. To determine the fully closed disk position, mea-
sure 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-de-
gree maximum disk rotation, the appropriate lever in-
dex mark must be offset one or two spline teeth coun-
terclockwise from the shaft index mark.
Refer to the appropriate actuator instruction manual
for instructions covering attaching the lever and adjust-
ing 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 remov-
ing the actuator and remounting it in the alternate
mounting style. Refer to the appropriate actuator in-
struction 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 reposition-
ing the actuator lever on the valve shaft.
For Fishtail disks, it will be necessary to
rotate disk 180 degrees so that the tail
of the disk will rotate into downstream
side of the valve.
Use the following procedure.
1. Refer to the appropriate actuator instruction manu-
al for assistance in disconnecting and removing actua-
tor lever. Avoid disturbing actuator turnbuckle adjust-
ment, if possible.
2. If valve disk is a Fishtail disk, rotate disk 180 de-
grees from the original position.
3. Position disk in 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 valve shaft is in top-dead-center or bottom-
dead-center in relation to the valve.
4. Note position of 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 valve-closed end of travel
and retain that position while performing the next
step.
b. Keeping hands away from actuator rod, hold the
actuator lever up to valve shaft so that the lever
end is in line with actuator rod end bearing. The
lever index mark that is most nearly in line with
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
valve shaft index mark for 1/2 through 3/4-inch
(12.7 through 19.1 mm) valve shafts and 2 spline
teeth from valve shaft index mark for 1 and 1-1/4
inch (25.4 and 31.8 mm) valve shafts. This offset
must be maintained during reassembly.
5. Record the alignment determined in step 4, remove
actuator lever, and shut off operating pressure to ac-
tuator.
6. Reassemble lever to actuator and adjust actuator
travel, if necessary, referring to the steps in the ap-
propriate actuator instruction manual. Be sure to use
the index mark alignment determined above rather
than those shown in figure 6.
