The PA35 actuator is a 35-square-inch 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 actuator comes with either 3 springs for a 3…15 psi signal range or 6 springs for a 6…30 psi signal range. Both ranges are adjustable to match bench loading with the requirements for your application. The yoke and the actuator housings are made of carbon steel and coated with epoxy for corrosion resistance.
The PA35 actuator normally operates in response to a 3…15 psi change in instrument signal, or a 12 psi range. The 3…15 psi
spring set is adjustable to 8…20 psi and the 6…30 psi spring set is adjustable to 16…40 psi to allow the user a wide range for shut-off
capability. This signal range causes the valve to stroke a distance of approximately 9/16…1 inch, depending on the associated RCV valve.
