CAUTION
To avoid damage to the tangential pins, disk pins, valve disk, or shaft(s) resulting from the application of excessive force,
use appropriate care when driving the pins into the disk hub and shaft(s). Use the right tool. Do not use excessive force.
12. Install the appropriate tangential pins, and disk pins. Use 2 tangential pins that will go through the upper shaft and
1 disk pin that will go through the lower shaft.
13. Refer to the Anti‐Blowout Design, Packing, Valve Shaft, Disk and Bearing Maintenance procedures in this manual
to re‐install the packing and anti‐blowout design.

Gasket Retainer

Valves with a two‐piece shaft use a gasket retainer and gasket (keys 20 and 21) to cover the lower shaft opening in the
valve body. The gasket is held in place by the gasket retainer and four hex head bolts and lockwashers (keys 23 and
22). When re‐assembling the valve, use a new gasket.
Be sure to center the gasket over the lower shaft bore before retightening bolts. Tighten down bolts evenly in a
crossover or star pattern.
Refer to table 6 for proper torque values.

Parts Ordering

Typical parts are shown in figure 9.
When corresponding with your Emerson Process Management sales office about a Control-Disk valve, identify the
valve as a Control-Disk and provide the valve serial number. For valve/actuator combinations assembled at the factory,
the valve serial number is stamped on the nameplate attached to the actuator.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Process Management should not,
under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.

Neither Emerson, Emerson Process Management, nor any of their affiliated entities assumes responsibility for the selection, use, or
