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
Fishtail
R
disk 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.
