摘要
The invention concerns an assembly of a valve body (A) and a seal (11). The valve body (A) includes a gas flow passage (4) and a valve shutter (6) mobile between an open position and a closed position obstructing the movement of the gases in the passage (4). The passage (4) being intended to be connected to a pipe (B) to enable gas to flow between them, the seal (11) being intended to be mounted between the passage (4) and the pipe (B) to provide a gas seal between them. The assembly is characterized in that the seal (11) forms a seat for the valve shutter (6) in the closed position. The seal provides, on the one hand, a seal between the passage and the pipe whether the valve shutter is in the open or the closed position and, on the other hand, a seal for the valve shutter in the closed position.
