1. Total volume to stroke piston down is equal to displacement volume plus clearance volume above piston.
Description
The 1066 is a direct-acting pneumatically operated actuator. The 1066SR is a spring-return pneumatically operated
actuator with a positioner (see figure 1). Both actuators are used for throttling or on-off applications with splined shaft
valves. These actuators can be used on eccentric disc 8532 and 8560 valves; CV500 and V500 valves; Vee-Ball™ V150,
V200, and V300 valves; and 9500 valves. The 1066SR fully retracts the piston rod towards the top of the cylinder upon
loss of loading pressure.
The actuator is field-reversible between PDTC (push-down-to-close) and PDTO (push-down-to- open) action
depending on mounting position (see figure 2). Refer to the Actuator Mounting section to change valve/actuator
action or its position. The G mounting adaptation is for 9500 rotary butterfly valves, and the F mounting adaptation is
for most other rotary high performance valves.
Specifications
Specifications for the 1066 or 1066SR rotary actuator are shown in table 1. Specifications for the actuator as it
originally came from the factory are stamped on a nameplate attached to the actuator.
