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-
