Spring Return & Direct Acting 90\u00b0 Pneumatic Valve Actuators-<\/strong>Up to 1,000,000 Cycles<\/strong><\/h2>\n

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.<\/p>\n

HOW IT WORKS<\/strong><\/h3>\n
\"pneumatic
Spring Return F Series<\/figcaption><\/figure>\n

The Assured Automation F Series actuators<\/a> 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.<\/p>\n

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.<\/p>\n

Additional accessories can be added such as Solenoids, Limit Switches, and Positioners as required.<\/p>\n
