The housing (6) has a valve upper part positioned in a connection thread (13). A valve body (3) is actuated by a spindle (2) and attached at a valve seat of the housing. A sealing device is arranged at the body on a side, which faces away from the spindle. The sealing device includes a cylindrical valve plunger (33), which is provided with a groove (34) concentric to a spindle axis. The groove receives a sealing disk (4), which projects out of the groove with a height of smaller than 30 percentage. A circular edge (35) of the plunger lies at the valve seat in an end position of the valve body. The sealing disk is made of elastomer i.e. rubber. |
