MVT28
MVT44
MVT56
MVT57
MVT actuator is electric bidirectional. The valve stem movement is produced by rotation of a screw spindle connected, through a gear train, to a synchronous bidirectional motor. An internal magnetic hysteresis coupling limits the torque on the valve stem, avoiding the usage of microswitches and protecting the actuator from overload.
