Foil/rubber lined butterfly valve

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.
