PROBLEM TO BE SOLVED: To make uniform the rate of gas flow between a plurality of manually operated valves laid in line and compact the whole construction. SOLUTION: The integrated valve unit 1 is structured so that the gas in the same sort is supplied a plurality of manually operated valves 2A-2F laid in line and the supplied gas is emitted from the valves 2A-2F. The integrated valve valve unit 1 has a flow passage block 3 where the valves 2A-2F 2A-2F are to be mounted rigidly. The flow passage block 3 is configured with a main passage 4 to allow the gas to flow through, branch passages 5 branching from the main passage 4 and leading to the inlet holes 2a and 2b of the valves 2A-2F, and a bypass passage 6 branching on the upstream of the main passage 4 and leading to the inlet hole 2b of the valve 2F positioned downstream of the main passage 4. Each branch passage 5 puts the inlet holes 2a and 2b of the adjoining valves 2A-2F in communication to each other. COPYRIGHT: (C)2006,JPO&NCIPI
