Abstract

The valve has a metal outer body (11) and an plastic insert (12) with associated valve cone (13). The valve cone has a rod (28) and a head (26). When the valve is closed, the cone head engages sealing on the facing edge of a shaft (22) in the insert. The rod is guided in the shaft and engages on the shaft base due to its length, when the valve cone is in closed position, and is subjected to a pressure, which is larger than a pre-set limit.
