ABSTRACT:
A flexible double toric sealing ring comprising two toric sealing ring sttures 2, 3 which ensure, respectively, a static seal and a dynamic seal. A counter ring is mounted radially on the second sealing ring structure and floats with it to allow self centering of the arrangement with respect to the valve seat. A sealing membrane 8 presents an elastically deformable structure 12 interconnecting the two sealing ring structures 2 and 3 while partially covering them. The two sealing ring structures 2, 3 are mounted on opposite sides of the middle section 11 of membrane 8. This double toric sealing ring can be advantageously applied to a butterfly valve.
