Hayward PSS Series Spring Return Pneumatic Actuators

The PS Series features a robust aluminum body with a three-layer Epoxy / Urethane coating for superior corrosion and abrasion resistance to handle harsh environments. With a very robust, lightweight, and extremely compact design, the PS Series also allows for ease of installation in tight spaces and less line weight where it is critical. Internally, the PS Series employs a scotch yoke design resulting in less friction and longer life of the actuator.
