Abstract
In a valve device (), when a valve () is closed, an output shaft of an actuator unit () is connected to the valve (). A control unit of the valve device () determines a control constant to be a value by which a response speed of the actuator unit () is smaller as ambient temperature is higher, and performs feedback control.
