Abstract
A valve for a dust collector comprises a bonnet and a valve body formed with a fluid port for introducing a pressure fluid filled in a pressure vessel; a diaphragm provided displaceably in accordance with an action of the pressure fluid introduced into a diaphragm chamber, for opening/closing a passage for making communication between the fluid port and a main dust collector body; and a disk member provided displaceably integrally with the diaphragm to shield the diaphragm so that it serves as a pressure-receiving surface for the pressure fluid when the pressure fluid is supplied to the main dust collector body.
