When a power loss is detected, a fail-safe system actuator is a system that stores energy to move the actuator to a predetermined safe position. This can be configured so that when the power to the actuator is withdrawn, the valve automatically returns to the open position. This is that, after the actuating force is removed, return to a predetermined position. Our Fail-Safe System Actuator needs a steady supply of power to function. This actuator is very effective as well as economical and safe to use.
