The valve has a valve plate (4) with a solid gasket (12) for full sealing and a lip seal (11) for preventing a reverse flow. A stop (4a) is formed for the valve plate for load removal of the solid gasket. The solid gasket and the lip seal are formed at an annular seal (10). The annular seal is tapered between the lip seal and the solid gasket. The solid gasket or the lip seal is made of a rubber material, particular ethyl-probylen-diene rubber or hydrogenated acrylonitrile-butadiene rubber. The valve plate is made of copper alloy which contains silicon and zinc as alloying components.
