Spring Return Actuator Valve ASR80 — with 17–14mm Star Reducer & Fixing Bolts
When air pressure fails in an industrial system, the consequences can be severe. The ASR80 (ACT80R) S14 Spring Return Actuator is engineered precisely for these moments — automatically returning the valve to a safe default position the instant pressure drops, without any manual intervention required.
Powered by compressed air, this pneumatic quarter turn actuator delivers precise, reliable control over butterfly and ball valves across a wide range of industrial applications. Internal return springs act as a built in failsafe, making it an ideal fit for emergency shut off systems, chemical processing plants, oil and gas pipelines, water treatment facilities, and HVAC installations where safety cannot be left to chance.
The included 17–14mm star reducer bridges the gap between the actuator's 17mm drive and a 14mm valve stem, ensuring a clean, secure connection without the need for additional adapters. Fixing bolts are included for a straightforward, stable installation straight out of the box.
