Asahi America CP79M2PSNST Plastic Pneumatic Actuator

Asahi/America CP79M2PSNST is a plastic pneumatic actuator in the Series 79P family designed for quarter-turn valves, offering a spring-return (air-to-spring) configuration with a 1040 N nominal return force. The actuator uses a double-piston, double rack-and-pinion arrangement to deliver a smooth torque profile through the stroke, and it provides a NAMUR mounting pad and an ISO output drive for straightforward mounting of accessories and valves. This family supports multiple configurations, including single-acting (air-to-spring) and double-acting designs, with the spring-return variant leveraging pre-loaded springs to ensure safe, dependable resets during maintenance. The CP79M2PSNST variant specifically emphasizes a plastic housing to suit chemical environments while maintaining reliable operation, and it aligns with Asahi/America’s emphasis on NAMUR-compatible mounting and flush-mount solenoid compatibility. Typical applications span chemical processing, water and wastewater treatment, mining, bleaching facilities, aquariums, and other settings requiring reliable, quarter-turn actuation of valves.
