Product Information

Mechanical Spring Return Failsafe Acuator

Mechanical Spring Return Failsafe Acuator

Stockcode:

Sun Yeh offer the S series mechanical spring return electric actuator. Rather than offering the standard / typical battery spring return system, Sun Yeh have opted to offer the mechanical spring return actuator which can be normally open or normally closed. The S series is also available as modulating failsafe and also has ATEX approval. 

In additional to the normal function, these actuators are designed to provide fail-safe positioning of valves and dampers upon loss of supply voltage. A mechanical spring set is utilized to position the controlled device to either the fully OPEN or fully CLOSED position without any external power source. A mechanical BUFFER employed at the end of the spring stroke for two-position control units to reduce the dynamic effects of the spring return system. A clutchless, leverless manual override design provides full-time manual positioning of the controlled device. The design has already won the new patent in Taiwan, U.S.A., Japan and China.
