Zusammenfassung:	A valve seal system for passageway through a valve body emerging through a first generally flat and rigid surface, having a valve member including a resilient seal with generally flat exposed surface adapted to be brought into contact with the generally flat rigid surface, and having a generally circular, raised resilient ring portion extending from the generally flat exposed surface, the raised resilient ring portion adapted to be compressed against the generally flat rigid surface to seal the resilient sealing means against the generally flat rigid surface when said valve member is moved to a closed position by virtue of the raised resilient ring portion being compressed against the generally flat rigid surface.
