The sealing principle of the centerline butterfly valve is to ensure that the sealing surface has a suitable surface roughness when processing the valve disc, and the synthetic rubber valve seat forms a suitable surface roughness value of the sealing surface during molding. When the valve is closed, through the rotation of the valve disc, the outer sealing surface of the valve disc squeezes the synthetic rubber valve seat, so that the synthetic rubber valve seat is elastically deformed to form an elastic force as the sealing specific pressure to ensure the sealing of the valve.
