The first valve chamber is supplied with a first fluid while the pressure supply chamber is supplied with a second fluid. The diaphragm is configured to displace depending on a pressure of the second fluid. The valve body is integrated with the diaphragm and is configured to move in an opening direction with the displacement of the diaphragm, thereby forming a main passage passing through the first valve chamber. The pressure relief mechanism is configured to relieve a pressure of the first fluid applied to the first port in a condition in which the valve body is closed.
