<p>Area shut-off valve for systems for supplying medical gases in hospitals, comprising: a single body (1) inside which there is produced a first inlet pipeline (3, 3') of the gas to be distributed; a first general shutter (4) for closing and opening of the valve which can be operated by means of a suitable lever (5) and positioned in said first pipeline (3); at least one pair of outlet pipelines (7, 8) for distribution of the gas placed downstream of said inlet pipeline (3, 3') and of said first shutter (4); and a second shutter (10) placed in one of said two outlet pipelines (7), hence downstream of said first shutter (4), and provided with a related operating lever (11);
the gas delivery pipeline (7) in which said second shutter (10) is positioned is connectable to one or more first user terminal devices of the gas located in the area of the hospital in which the valve is installed; the other of said gas distribution pipelines (8) is adapted to distribute the gas towards one or more second user terminal devices of the gas also located in said area, so that said second distribution pipeline (8) can deliver gas to said second terminal devices even if the second shutter (10) of the first outlet pipeline for distribution of the gas to said first terminal devices is moved to the closed position.</p> |
