Actuator, Pneumatic (Type PA58)

The PA58 actuator is a pneumatic, multi-spring diaphragm actuator designed specifically to fit the RCV product line. The actuator can
be used with a wide range of valve solutions from larger process valves to high-pressure applications. The actuator is field reversible
(without additional parts) allowing flexibility within the field. This actuator is available air-to-open or air-to-close. The yoke and the actuator housings are made of carbon steel and coated with epoxy for corrosion resistance.

FUNCTION

The PA58 actuator normally operates in response to a 24 psi range. The signal range causes the valve to stroke a distance of
approximately 1 inch. Depending on the associated RCV valve, a positioner is needed if a shorter stroke is necessary.
