Spring Return Electric Actuator

Short Description:

The spring-return quarter-turn electric actuator belongs to the mechanical spring-storage type of actuator. Under normal power supply, the motor drives the actuator to open the valve while simultaneously compressing (charging) the spring. In the event of an emergency power failure, the stored spring energy is released to drive the actuator, returning the valve to its safe position (fully open or fully closed). The movement is smooth and controlled, preventing water hammer and the risk of pipe burst.
