The Industry Leader in Spring-Return Actuators for Critical Isolation Service

When quarter-turn and modulating emergency shutdown or shutoff capability is required.  Available in both regular and high-temp configurations for your most challenging application. 

RCS’s SurePowr® spring-return electric actuators utilize heat treated alloy steel springs to assure a reliable mechanical solution for shutoff or isolation situations. This design provides a cost-effective, low maintenance, proven alternative to pneumatic, hydraulic, electro-hydraulic or battery fail-safe methods. The SurePowr series is capable of performance in elevated temperatures up to 400° F (250° C) for one hour without the need for external thermal insulation; up to four hours with external thermal insulation, and also for different durations at higher temperatures in compliance with NFPA 130 and NFPA 502; low temperature versions are also available.
