Asahi America AP79PSNST Pneumatic Actuator and Ball Valve

AP79PSNST is a preassembled Series 79P pneumatic actuator and ball valve package from Asahi/America, engineered for quarter-turn on/off control with a spring-return (single-acting) operation. The unit combines a Type-21 ball valve with a rotary pneumatic actuator and 3/4" NPT end connections, while control air ports are 1/4" NPT. NAMUR mounting is provided to accommodate common solenoids or positioners, enabling easy accessory installation. This package is designed for applications that require dependable fail-safe actuation in process piping, such as chemical processing, water treatment, and general industrial systems requiring compact, robust 90-degree valve operation. The AP79PSNST maintains the standard 79P footprint and interfaces with other 79P valve/actuator configurations, making interchangeability straightforward within the Series 79P family. In practice, it offers a compact, integrated solution where quick, reliable actuation and tight shutoff are essential, with 3/4" NPT piping compatibility for mid-range flow rates.
