Actreg ASR1750-F14-DS36 Rack & Pinion Pneumatic Actuator – 90° – Anodised Aluminium – SIL?3

The Actreg ASR1750-F14-DS36 is a rugged, high-torque pneumatic actuator built for precision 90° (quarter-turn) valve operations in extreme industrial environments. Featuring a robust rack & pinion mechanism, this actuator delivers strong performance for large valves. Encased in a hard-anodised aluminium housing, it withstands corrosion and mechanical stress, even in demanding applications. The actuator supports ISO 5211 F14 mounting and features a sturdy 36?mm DS36 square drive shaft, allowing seamless integration with oversized valve interfaces. Fully certified to SIL?3, the ASR1750 is ideal for safety-instrumented systems in sectors such as oil & gas, petrochemical, power generation, and process automation.
