Product Description

Center Line Sealing Butterfly Valve
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 on the seat to form an elastic force used as a sealing specific pressure so as to guarantee the tightness of the butterfly valve.
