Centric Construction Butterfly Valve
Categories：Centric Construction Butterfly Valve
The turning center of the butterfly plate is on the centerline 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.
