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
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

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. - Page 4 Instruction Manual 9500 Valve February 2019 D100380X012 Table 3.

Instruction Manual 9500 Valve February 2019 D100380X012 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. - Page 7 Instruction Manual 9500 Valve D100380X012 February 2019 Figure 4. Grounding Assembly ACTUATOR END PLATE 37A6528‐A 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.

Instruction Manual 9500 Valve February 2019 D100380X012 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. - Page 15 Instruction Manual 9500 Valve D100380X012 February 2019 Figure 6.
