Main Features: The turning center of the butterfly plate is on the center line of the valve body and the sealing face section of the butterfly plate. In closing, the ex-circle sealing face of the butterfly plate will extrude the valve seat made of synthetic rubber, generating elastic deformation...
PTFE Lug Butterfly Valve
The Lug type butterfly valves are widely used in water supply and drainage, hydre/thermal power, building project as well as industrial water system, such as steel and petrochemical.
