Asahi America CP79M2PSNST Pneumatic Actuator

The Asahi/America CP79M2PSNST Pneumatic Actuator is a spring-return, Series 79P rotary actuator designed to drive quarter‑turn ball and butterfly valves in demanding or corrosive environments. It is a single‑acting, air‑to‑spring model with pre‑loaded springs for a reliable fail‑safe return when air pressure is removed. The Series 79P family offers three standard body materials—glass‑reinforced polyamide, cataphoresis & Rilsan‑coated cast aluminum alloy, and 316 stainless steel—each with ISO output drive and NAMUR mounting pads for easy installation of accessories. Air ports are 1/4" NPT and the NAMUR pattern accommodates flush‑mount solenoids, enabling compact, clean valve actuation. For sizing, the Series 79P actuators cover a wide torque range, from about 59 to 40,710 in‑lb at 80 psi, allowing use with a broad spectrum of quarter‑turn valves. Common applications include chemical processing, water treatment, mining, bleach plants, aquariums, and power generation facilities where reliable actuation and corrosion resistance are essential. The CP79M2PSNST variant aligns with these design principles, delivering a robust, corrosion‑resistant platform for automated valve control in harsh processes while leveraging NAMUR accessories and ISO mounting standards for straightforward integration.
