 Corrosion-resistant flange fluorine butterfly valve Product Overview: 

 Butterfly valve of fluorine corrosion-resistant flange with spherical sealing surface of the ladle lining PTFE disc, the easy operation of the valve, tight sealing performance, long service life; can be used to quickly cut or adjust the flow with. Require reliable sealing and good regulation characteristics occasions. 

 D41F4, with F46-16C resistance to corrosion lined butterfly valve used with the spherical sealing surface of the ladle lining PTFE disc, the light valve operation, tight sealing performance, long service life; can be used to quickly cut off or Adjust the flow purposes. Require reliable sealing and good regulation characteristics occasions. Body using split at both ends of the valve shaft sealing is controlled by the rotation of the base surface between the disc and seat and Viton; to ensure that the valve shaft in contact with the cavity fluid medium. Widely used in various types of industrial pipeline liquids and gases (including steam) in the delivery of severe corrosive media use situations, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, aqua regia has a strong corrosion of media.
