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

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
5
9500 Valve

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.
Instruction Manual
D100380X012
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.
