This valve device is provided with: a body (4) forming a fluid channel (3) that communicates with the combustion chamber of an internal combustion engine; a valve (2) rotatably housed within the fluid channel and able to vary the valve opening of the fluid channel; an electric actuator (5) for driving rotation of the valve towards the closed side or the open side, between a fully open position, a fully closed position, and an intermediate position which is a prescribed valve position between the fully open position and the fully closed position; a valve energization unit (28) for energizing the valve towards the open side from the fully closed position; and an ACT control unit (6) for control of driving by the electric actuator (5). The set load of the valve energization unit is smaller than the set load at which return to the intermediate position from the fully closed position is possible by the energizing force of the valve energization unit alone, and when the valve position is closer towards the closed s
