Hayward PAD/PAS Pneumatic Actuators

Hayward Series PAD/PAS Plastic Pneumatic Actuators

Series PAD pneumatic actuators are air-to-air (double acting) actuators, while the PAS Series are air-to spring (fail safe) actuators. Air-to air actuators require air pressure for both actuation cycles, open and close. Air-to spring actuators utilize a mechanical spring return unit, enclosed in a plastic housing, to operate one of the actuation cycles. This type of actuator can be set to have the spring, rather than air pressure, open or close the valve. Hayward PAD and PAD pneumatic actuators feature a proven vane design for extremely reliable service with minimum maintenance. This design utilizes only one moving part, the vane assembly.
