The present article is a fluid control valve used, for example, to immediately discharge a large amount of pressure fluid at high speed for wiping off dust attached to a bag filter of a dust collector. The fluid control valve includes: a body having two pressure fluid inlet/outlet ports; and a bonnet attached on an upper part of the body (See Reference drawings 1 and 2). The two pressure fluid inlet/outlet ports communicate with each other via a not illustrated passage formed inside the body. In the passage, a not illustrated valve body integrally formed with a diaphragm is provided. When using, for example, a not illustrated pressure fluid supply source such as an air tank is connected to one of the pressure fluid inlet/outlet ports, and a not illustrated injection pipe connected with an upper opening of the bag filter provided inside the dust collector is connected to the other of the pressure fluid inlet/outlet ports. In this state, when the pressure fluid is supplied to the present article, the valve body is opened according to the pressure of the pressure fluid, and the pressure fluid is injected inside the bag filter via the injection pipe. The injected pressure fluid causes impact on the bag filter to remove the dust attached to an outer periphery of the bag filter.
