The F Series Pneumatic valve actuator offers a simple and cost effective solution for valve automation needs, and also for use on quarter turn (90 degree) ball valves, plug valves, dampers, and resilient seated and high performance butterfly valves. This pneumatic valve actuator is available in double acting and spring return fail safe configurations.
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 to either open or close. Position indication is visual with a top mounted indicator.
Key features include: Compact rack and pinion design for tight spaces, Has up to 1 Million Cycles, Self Lubricating Piston Seals, Double Acting and Spring Return models either Fail Open or Fail Close, Direct mounting to ball and butterfly valves.
