The pinch valve (1) has a deformable tubular valve (6) which is defined in the main channel (11). An actuating structure (28) is provided to open the tubular valve for releasing the fluids and to close the tubular valve by fitting closely against a valve seat surface (27) of the valve seat (25). The valve seat is defined with an additional passage (35) in the interior of the main channel for the flow of additional medium. The valve seat surface of the valve seat is sealingly pressed with the tubular valve to shut off the main channel. |
