Asahi BP79PSNST Pneumatic Actuator

Asahi BP79PSNST Pneumatic Actuator is a Series 79 spring-return actuator designed for 1-inch Type 21/23 ball and butterfly valves, packaged in Asahi/America’s Duo-Bloc 21 assemblies. It provides up to 1040 N of actuation thrust under pressurized air, enabling reliable fail-safe positioning for quarter-turn valves in process piping. This BP79PSNST variant is part of the BP79PS family within the Series 79 line, and the spring-return configuration ensures the valve returns to its designated safe position when air supply is removed. Common applications include industrial valve automation in chemical processing, water treatment, and other process environments where compact packaging and proven performance are required.
