Abstract
The present invention provides a valve assembly, comprising a multiway valve (9) with a fitting surface (10) and a fluid manifold (7) with a mounting surface (8), wherein an opening of at least one branch channel lies opposite an opening of a respective channel of the multiway valve (9) in order to provide a fluid connection between the fluid manifold (7) and the multiway valve (9), and with an elastic sealing plate (1) with a plate-like body and through holes (2a-2e, 3a-3d) for the openings disposed between the mounting surface (8) and the fitting surface (10) and covering approximately completely the fitting surface (10) of the assigned multiway valve (9), wherein each through hole (2a-2e, 3a-3d) is surrounded by an annular sealing lip (4) formed on the elastic sealing plate (1), wherein the elastic sealing plate (1) is provided with an outer hygienic sealing profile (5) formed along the edge (6) on both sides of the sealing plate (1) in order to avoid a capillary entry of dirt and bacteria into the area between the multiway valve (9) and the fluid manifold (7).
