A valve (10) is specified, having a closing member (2), co-operating with a valve seat (11), said closing member (2) and said valve seat (11) each having in their contact area a closing surface (16, 17), which bear against each other in the closed state. With such a valve the improvement of the tightness must also be possible, even with a simple construction. For this purpose one of the closing surfaces (16, 17) is coated with a coating material (18), which is softer than the material of the other closing surface. |
