ルブ。[Claims for Utility Model Registration] 1. A main valve that opens and closes a flow path between a primary port and a secondary port, and a bypass flow path provided between the primary flow path and the secondary flow path. 1. A control valve characterized in that the control valve is provided with a bypass valve that automatically opens and closes the bypass flow path. 2. The control valve according to claim 1, wherein the bypass valve is automatically opened and closed by application of air pressure. 3. The bypass valve includes a driving air pressure supply port that supplies air pressure, a valve seat provided in the bypass flow path, a valve body that opens and closes the bypass valve by contacting or separating from this valve seat, and this valve body. a piston for driving the valve body that presses the valve body against the valve seat or moves it away from the valve seat by applying air pressure from the drive air pressure supply port; and a piston that pushes the valve body against the valve seat when the application of the air pressure is cut off. 3. The control valve according to claim 1, further comprising a spring that biases the control valve toward or away from the control valve.
