Actreg Pneumatic Actuator ASR2500-F16-DS46 – Rack & Pinion, 90°

Product Description

Actreg Pneumatic Actuator ASR2500-F16-DS46 – Rack & Pinion, 90° Rotation, Anodised Aluminium, SIL?3

The Actreg ASR2500-F16-DS46 is a heavy-duty spring-return pneumatic actuator designed for high-integrity automation of large quarter-turn valves. Featuring a robust rack & pinion mechanism providing 90° rotation, it is engineered for durability and safety in industrial environments. With an ISO 5211 F16 mounting flange and a 46?mm DS46 square drive shaft, this actuator ensures compatibility with oversized valve assemblies. Its hard-anodised aluminium housing provides excellent resistance to corrosion and wear. Fully SIL?3 certified, the ASR2500 is ideal for integration into functional safety systems across sectors such as oil & gas, power generation, water treatment, and petrochemical processing.
