Abstract: A valve includes a housing and vane that is movable to a predetermined position. An actuator mechanically couples to the movable vane. The actuator is a wire device fabricated from shape memory alloy which, when activated, urges the movable vane toward the predetermined position. A power supply is configured to activate the actuator in response to an activation command and an indication that the movable vane is not in the predetermined position.
