Abstract
A valve device includes a valve, an actuator actuating the valve, a control unit controlling an opening degree of the valve, a return spring biasing the valve only in a valve-closing direction, and a mechanical stopper controlling a rotating limit of the valve in the valve-closing direction. The valve is defined to rotate on a plus side from the full-close position in a valve-opening direction and to rotate on a minus side from the full-close position in a direction opposite from the valve-opening direction. The mechanical stopper stops the valve at a stopper position which is set on the minus side from the full-close position, and a predetermined overshoot range is defined between the full-close position and the stopper position.
