Plastic Pneumatic Valve Actuators Hayward Series PKD/PKS


Hayward, Industrial, Flow Control Systems

Plastic, Pneumatic Valve Actuators, Hayward, Series, PKD, PKSRugged Design: Hayward PKD and PKS pneumatic valve actuators feature a proven vane design for extremely reliable service with minimum maintenance. This design utilizes only one moving part, the vane assembly, to product torque sufficient to operate all sizes of ball valves and butterfly valves up to 8" in size. The actuator body is constructed from an aluminum alloy and is epoxy coated.

Two Modes of Operation: Series PKD pneumatic valve actuators are air to air (double acting) actuators. While the PKS Series are air to air (fail safe) pneumatic valve actuators. Air to air pneumatic valve actuators require air pressure for both actuation cycles, open and close. Air to spring pneumatic valve actuators utilitize a mechanical spring return unit to operate one of the actuation cycles. This type of pneumatic valve actuators can be set to have the spring, rather than air pressure, either open or close the valve.

Modular Mounting Options: PKD and PKS pneumatic valve actuators feature a modular mounting system for the many different options that are available for these actuators. Options mount separately to the actuators, they are not built in. This allows for a specific applications. You never have to pay for an "option package" with features you may not need. Modular mounting also means you can add options to the actuator in the field.

Manual Override Standard: Both PKD and PKS pneumatic valve actuators can be operated manually in the event of air or electric failure.
