F Series Pneumatic Valve Actuators

Spring Return & Direct Acting 90° Pneumatic Valve Actuators-Up to 1,000,000 Cycles

For use on quarter turn (90 degree)ball vales, plug valves, dampers, and resilient seated and high performance butterfly valves, the F Series Pneumatic valve actuator offers a simple and cost effective solution for valve automation needs. This pneumatic valve actuator is available in double acting and spring return fail safe configurations.

HOW IT WORKS

pneumatic valve actuator
Spring Return F Series

The Assured Automation F Series actuators operate with compressed air ranging from 40-120 PSI. F Series require no lubrication due to the carbon filled Teflon guide bands which keep the piston seals from wear and are self-lubricating.

The rotation of 90 degrees is caused by two dual opposed piston gear racks, which turn a center drive shaft. The drive shaft when coupled to a quarter turn valve drives the valve either open or closed. Position indication is visual with a top mounted indicator.

Additional accessories can be added such as Solenoids, Limit Switches, and Positioners as required.
