Product Description

The Fisher 1052 is a spring and diaphragm rotary actuator.
The 1052 actuator can be installed on rotary­shaft valve bodies for throttling or on­off applications. The actuator
linkage features a clamped shaft lever and a single pivot point to reduce lost motion between the actuator and the
valve.
The 1052 actuator delivers several operations and maintenance advantages. It has an inherent failsafe position on loss
of operating air. In contrast to piston style actuators that rely on o­ring seals, the double­sided diaphragm in the 1052
actuator provides a longer service life.
Powder paint coating is standard and offers an excellent corrosion­resistant finish on all external steel and cast iron
parts.
The 1052 actuator is used with a rotary valve to control process fluids that can be used in a wide variety of applications.
They are typically used with other interface components (valve positioner or solenoid valve) to provide a final element
subsystem for a SIF.
