Scope of Manual
This manual provides installation, adjustment, and
maintenance information for Type 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.

office 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 Fishtailr

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:
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

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.

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.

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

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.

Figure 4. Grounding Assembly
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.
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.
