Double Flange Center Line Sealing Butterfly Valve
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 on the seat to form an elastic force used as a sealing specific pressure so as to guarantee the tightness of the butterfly valve ,Butterfly valve is used for isolating or regulating flow and its function allows for quick shut off. There are many different kinds of butterfly valves, each adapted for different pressures and different usage in the industry.
