摘要

The valve (10) has a body (12) presenting two parallel sides (14, 16) and equipped with a rubber crown (30) at periphery. The crown has two lips (32, 34) whose upper side (33) is radially beveled with a sealing contact bevel that is inclined in a centripetal manner. The lips are formed alternatively in extension on both sides of an axle (20) and on the two sides of the body of the valve. The crown is made of different rigidity multi-layered material such as natural or synthetic rubber material and highly fluorinated polymeric material (FPM) or fluorosilicone rubber material.
