Provided is a control valve including a main valve and a sub valve which are driven by a single solenoid, capable of suppressing wearing or hitting sound from generating when the sub valve is closed. The control valve (10) includes a sub valve body (36) mounted on or dismounted from a sub valve seat (34) formed in a main valve body (30) to open or close a sub valve; a power element (6) provided at one end of a body (5) to detect the target pressure and generating a driving force to drive the main valve body (30) in a valve open direction if the target pressure is lower than a set pressure; a solenoid (3) provided at the other end of the body (5) to generate a solenoid force to drive the main valve body in a valve close direction; and an operation rod (38) disposed between the power element (6) and the solenoid (3) to directly transmit the solenoid force to the power element (6) without passing any one of the main valve body (30) and the sub valve body (36). |
