global brand of quality electric actuators from 50Nm to 260Nm

________________________________________________________________________

S Series of quarter turn Failsafe electric actuator series
 
 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

For the first time we are now pricing the full range of Sun Yeh S Series failsafe electric actuators online for purchase. Make your selection from the models shown below. See Accessories tab within product page for pricing on additional features such as ATEX approval and modulating controller.
