A control valve is configured to drive a main valve and a sub-valve by a single solenoid enables obtaining a flow rate regardless of the size of the main valve when the sub-valve is opened. The control valve (1) has a sub-valve seat (34) formed at a portion of a body (5). The control valve has an actuation switching mechanism which integrally displaces an actuation rod (38) with a main valve body (30) while maintaining a closed state of a sub-valve in a control state of a main valve and relatively displaces the actuation rod (38) with respect to the main valve body (30) even after the main valve is closed to displace a sub-valve body (36) in a valve opening direction. |
