Series PCD/PCS
For use with all sizes and types of Ball Valves and Butterfly Valves
GENERAL DESCRIPTION
All-Around Best Choice: Hayward® Series PCD and PCS Actuators are the best choice for applications requiring pneumatically actuated true union ball valves, three-way ball valves or butterfly valves. These actuators are available in models with appropriate torque outputs for all valves from 1/4" all the way up to 24" pipeline size.
Two Modes of Operation: The Series PCD actuators are air-to-air (double acting) actuators, while the PCS 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 to operate one of the actuation cycles. This type of actuator can be set to have the spring, rather than air pressure, either open or close the valve.
Compact Design: Series PCD/PCS actuators feature a four piston rack and pinion design. This design results in a high torque output actuator, yet one that is very lightweight and compact in comparison with other rack and pinion actuators.
Solenoids for Air Control: Electric solenoids are used to control the compressed air flow to the actuator. A variety of solenoids are available for this purpose.
Manual Override Standard: Both PCD & PCS actuators can be operated manually in the event of air or electric failure.
