P Series Pneumatic Valve Actuators

The Assured Automation P Series pneumatic actuators offer a simple and cost effective solution for your valve automation needs. For use on quarter turn (90 degree) ball valves, plug valves, dampers, and resilient seated butterfly valves.

These are dual scotch yoke style actuators which have higher torque values at the start and end of the stroke. This characteristic makes them ideal for use on resilient seated butterfly valves. This also makes them suitable for valves and applications requiring a higher break torque.
