Sanitary clamp butterfly valve

The sealing principle of the sanitary fast-install butterfly valve is to ensure that the sealing surface of the valve plate has a suitable surface roughness value during the processing of the valve plate, and the synthetic rubber valve seat forms a suitable surface roughness value of the sealing surface during compression molding. When the valve is closed, through the rotation of the valve plate, the outer sealing surface of the valve plate squeezes the synthetic rubber valve seat, so that the synthetic rubber valve seat produces elastic deformation. The elastic force is used as the sealing specific pressure to ensure the sealing of the valve.
