Our spring return actuator integrated spring driven pinion and rack mechanism to provide torque ranges from 50Nm to 260Nm.When power is supplied, the spring mechanism is compressed to store energy for movement. Once the power is lost, actuator will be driven to fail safe position (either Fail OPEN or fail Closed) in either clock wise (CW, standard) or counter clock-wise (CCW, optional) rotation.
The failure close/open time from 3 seconds to 12 seconds.
