A switching device for optionally passing a flow of medium, such as a highly pressurized gas, through a first or second treatment member (2, 3), in which the medium is subjected to a treatment, such as filtration, heating, cooling or the like, comprises a medium inlet, a medium outlet and two distribution valves (1, 5), of which the valve bodies, which are provided with passages, are attached to a common rotation pin (10). For safety's sake, safety valves (12, 13, 14, 15) are arranged in the connections between distribution valves arranged at the inlet and at the oulet and the two treatment members. |
