Abstract

Safety valve has a seal which acts dependent upon the applied pressure, and the valve cone comprises a PTFE material, with a sealing lip on the side facing the material. The lip is conical on its outermost peripheral surface. The valve cone has a pressure disc on the side turned away from the sealing lip, which is made of metallic material. The valve seat is likewise of PTFE and similarly on its side turned towards the valve cone has a sealing lip. The valve cone is metal reinforced, and is fitted with a folding bellows.
