Seal for pressure dependent valve - has jointing material in sealing area with membrane lip providing spring action

摘要

The valve has a seal which operates dependent upon pressure up to a present limit. The pressure force of the seal on the valve and seat results from the applicable operating pressure until the preset pressure is attained. The sealing component (4) is metal whilst it and/or the valve seat (2) and the cone (5) at least in the sealing area also comprise a jointing material. The sealin lip (4a) of the seal has a spring effect and has an equally distributed wall strength.
