The unit has a housing arrangement in which a conduit is sealable by a face plate. A rotation axle is arranged approximately parallel to the conduit in the arrangement. The plate is connected with the axle such that plate is rotated by the rotation of the axle over the conduit. A sealing unit (22) in a region of the conduit is in contact with a side of the face plate in a closed condition of the valve unit to form a sealing surface.
