Introduction
Scope of Manual
This instruction manual includes installation, adjustment, maintenance, and parts ordering information for the Fisher
1069 dual piston pneumatic rotary actuator (see figure 1). Instructions for the control valve body, the valve positioner,
and accessories are included in separate instruction manuals.
Description
The 1069 dual piston pneumatic rotary actuator is for use with larger sizes of rotary shaft valves such as NPS 16
through 24 V250 ball valves and NPS 30 and 36 8510 eccentric disk valves. The 1069 actuator can be used for
throttling service when equipped with a valve positioner, or for on-off service when equipped with switching devices.
