A line diverter has a valve body (2) comprising at least two channels (3), the valve body (2) being displaceable within a casing (1) provided with at least three tubular connection pieces (4). The casing (1) is gastight. In between valve body (2) and casing (1) there is provided a free gas chamber (12), within which the valve body (2)--with the exception of the front surfaces assigned to the end surfaces (8) of the channels (3)--is so arranged that it does not have any contact with the inner surfaces of the casing. A sealing arrangement, which may be employed also for one-channel or multi-channel rotary diverters, comprises a sealing plate (7) within the casing (1), the sealing plate being provided with at least one open passage area corresponding to the channel end surfaces (8). The sealing plate (7) is compressed against the channel end surface(s) by a force acting perpendicularly to the direction of displacement.
