Abstract
An actuator with a motor produces a motive force to control a valve. The actuator includes a driving portion coupled to the motor to receive the motive force from the motor. Additionally, the actuator includes a driven portion coupled to the driving portion, the driven portion being coupled to a valve stem to drive movement of the valve between at least one of an open position and a closed position. The actuator includes a clutch positioned between the driving portion and the driven portion, the clutch being a one-way clutch to transmit motive force from the driving portion to the driven portion and block transmission of the motive force from the driven portion to the driving portion. Additionally, the actuator includes a brake arranged proximate the clutch to stop transmission of the motive force between the driving portion and the driven portion.
