Abstract:

This valve device (1) has: a valve main body (2) that compartmentalizes a valve chamber (21) provided with an NO outflow port (25) and NC outflow port (24) through which a fluid flows; and a valve body (3) that opens/closes the NC outflow port (24) and NO outflow port (25). The valve body (3) includes: a diaphragm (6) disposed in a manner so as to cover the valve chamber (21); and a drive means (4) that, by means of pressing the diaphragm (6), can open/close the NC outflow port (24) and NO outflow port (25). A first valve seat (24b) and second valve seat (25b) are formed at the periphery of the NC outflow port (24) and NO outflow port (25). The diaphragm (6) comprises an elastic material of which the JIS-K6253 durometer A hardness is A50-A85. The pressure of the seated diaphragm (6) to the first valve seat (24b) and second valve seat (25b) is 0.5-1.0 N/mm2.
