摘要：
A directional valve includes a fixing lug (13), which is arranged eccentrically to a valve membrane (16) and is arranged at a valve housing (15). The dimensions of the fixing lug (13) are selected for fixing the valve membrane (16) relative to the sealing surface (2) of valve seat (1). The size of the eccentric offset (x) is in a range between 8% and 15% of the axis length (D) of the greatest longitudinal extension of valve membrane (16).
