zshwf series fluoroplastic butterfly valve adopts a ptfe lined butterfly plate with a spherical sealing surface. the silicone rubber gasket at the base of the valve seat adjusts the sealing performance of the valve. the valve is portable and has a tight sealing performance. long service life; can be used for quick cutting or adjusting the flow rate. the valve body adopts a split type, and the sealing of both ends of the valve shaft is controlled by the fluororubber on the rotating base surface between the butterfly plate and the valve seat; the closed connection ensures that the valve shaft does not come into contact with the medium in the flow channel.
