1. Product Title

Jamesbury C0221605‑ Pneumatic Rack‑and‑Pinion Valve Actuator

2. Product Overview

C0221605 is a heavy‑duty rack‑and‑pinion pneumatic actuator manufactured by Jamesbury (Valmet), engineered for quarter‑turn ball and butterfly valve automation within process industries. It converts compressed air supply into rotary torque to open or close process valves, supporting spring‑return fail‑safe or double‑acting operation modes. Its aluminum alloy housing provides corrosion resistance for chemical, power‑generation, water‑treatment and oil‑gas environments. Integrated position indicator visualizes valve status, and it complies with ISO 5211 mounting standard for direct valve assembly. As original spare, it resolves actuator torque output and spring‑return faults for automated on‑off valve loops.
