The VTMR series spring return electric actuator employs a spring-driven pinion and rack mechanism, providing torque ranges from 50Nm to 300Nm. This actuator operates under normal power conditions with a motor-driven system that simultaneously stores energy in the spring. In the event of a power outage, the spring releases this energy, activating the actuator to ensure that the connected equipment swiftly returns to a safe position, either fully open or closed. This process is secure and stable, effectively preventing any sudden pipe bursts (hammer-blow effect).
