Curtiss-Wright Bettis RPB450 Pneumatic Valve Actuator

Curtiss-Wright Bettis RPB450 Pneumatic Valve Actuator is a rack‑and‑pinion style device that converts compressed air into rotary motion to automate a valve, typically delivering about a 90° stroke. It operates from a controlled air supply up to 120 psi, making it compatible with standard industrial pneumatic control schemes. This Bettis actuator is part of the RP/RPB/RPC family and is designed for reliable cycling in valve automation applications, with a robust housing built to withstand demanding conditions. The 120 psi operating pressure is a key verified specification that governs its actuation performance, while its modular design supports straightforward integration with Bettis valve assemblies and mounting patterns used in industrial installations. By providing precise, repeatable valve actuation from a compact, purpose‑built package, the RPB450 enables automated process control and remote operation in industrial settings where dependable pneumatic actuation is required.
