Curtiss-Wright Bettis RPB1000-S Pneumatic Actuator Valve

The Curtiss-Wright Bettis RPB1000-S is a 120 psi rack-and-pinion pneumatic actuator designed to deliver precise 90-degree valve operation, with a compact layout that provides smooth torque transfer, predictable stroke, and reliable cycling for quarter-turn valves in harsh plant environments. The -S suffix denotes a spring-return configuration, meaning the valve will return to a safe, closed position when supply air is interrupted—a critical fail-safe feature for safety-critical shutdowns. Wetted parts are PFA-lined over a CD4MCu core, marrying chemical resistance with mechanical strength to withstand aggressive process fluids, while the PFA lining supports cleanability and corrosion resistance in CIP-enabled systems. Designed for integration with Bettis valve packages, the RPB1000-S offers modular construction for straightforward field maintenance, robust torque delivery at 120 psi, and broad applicability across energy, chemical processing, and power-generation sectors that demand dependable, fail-safe quarter-turn actuation.
