The VTMR series spring return electric actuator employs a spring-driven rack and pinion mechanism, delivering torque capacities ranging from 50Nm to 300Nm. Under normal power conditions, the actuator uses a motor-driven system to charge the spring. In the event of a power failure, the spring releases its stored energy, immediately returning the connected devices to a safe position, either fully open or closed. This design ensures smooth and stable operation, effectively preventing any sudden pipe bursts (hammer-blow effect).
