Ball Valves - Unique and Flexible Lip Seal for Valve Seat

Ball Valves - Unique and Flexible Lip Seal for Valve Seat

The first contact part between the ball and the sealing ring is made into a cantilever lip, so as to create a buffer between the valve body and the sealing ring, which automatically compensates for the leakage caused by the wear of the valve seat, the change of temperature and pressure, and the plastic deformation, and improves the sealing performance and lifecycle.
