Tri-eccentric multi-layer hard seal butterfly valves feature small flow resistance, low impact erosion of the seal surface, low pressure drop, small open-close
torque, good technological performance and wide ranges of applicable pressure and temperature.
This series of products adopt tri-eccentric inclined-tapering seals that feature low wear during opening and closing, small frictional torque and flexible operation. In addition, as the rotating radius of the tapering butterfly plates is larger than the rotating radius of the seal pair contacts, the tapering butterfly plates will become tighter and tighter upon closing, can realize self locking and prevent butterfly plate over-position.
Butterfly plate seal rings of the valves are overlapped soft and hard metal sheets which have characteristics of both flexible seals and soft and hard multi-layer
seals, with sound sealing performance even in corrosive or high temperature conditions.
