Industrial B79PFSW115AST Pneumatic Actuator Assembly

The B79PFSW115AST is a 1-inch valve pneumatic actuator assembly from Asahi/America’s Series 79P line, delivering spring-return actuation for inline valves. This configuration is designed to operate 1" valve assemblies in thermoplastic valve systems used in chemical processing, water treatment, and other harsh-media environments where corrosion resistance is essential. As part of the 79P family footprint, it provides a compact, straightforward path to automate valve control with standard mounting interfaces and the option to add accessories such as limit switches or solenoids (sold separately) for position indication and remote control. The spring-return mechanism ensures the valve returns to its default position once compressed air is released, providing a predictable fail-safe response in safety-critical piping applications. Built to integrate with Asahi/America’s corrosion-resistant valves and piping systems, this actuator assembly helps streamline installation for 1" flow paths and offers consistent, repeatable actuation in demanding industrial settings.
