D371F4 D371F46 folder lined butterfly valve
Fluorine butterfly valve with the spherical sealing surface of the fluorine plastic bag lining the disc, together with the seat base of the silicone rubber pad to adjust the valve sealing performance; easy operation of the valve, tight seal performance, long life; can be used to quickly cut or adjust the flow. Require reliable sealing and good regulation characteristics occasions. Body using split valve shaft the side of fluoride rubber seal between the rotating disc and valve seat base surface to control, so as to achieve the compact structure, beautiful appearance, the process is reasonable and reliable performance. Ensure that the valve shaft does not contact with the cavity fluid medium is very convenient to replace the valve axis, the valve does not require demolition of Lili pipeline to complete. Use the occasion of the delivery of products are widely applied to various types of industrial pipeline liquids and gases (including steam), especially those with severe punishment corrosive media such as sulfuric acid, hydrofluoric acid, phosphorus acid, chlorine, alkali, aqua regia, etc. has a strong corrosive media.

used in -50 ℃ -150 ° C, various concentrations of water, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants, various concentrations of alkali organic solvents andother corrosive gases, liquids medium pipeline apply.
The fluorine butterfly valve with the spherical sealing surface of the ladle lining PTFE disc, together with the seat at the base of silicon rubber pad to adjust the valve sealing performance; easy operation of the valve tight sealing performance, ultra-long life; can be used to quickly cut off, or adjust the flow purposes. Require reliable sealing and good regulation characteristics occasions. Fluorine valve body, using split, and fluorine rubber to control both ends of the valve shaft is sealed by the rotation of the base surface between the disc and seat; to achieve the compact structure, beautiful appearance, the process is reasonable and reliable performance. Ensure that the valve shaft does not contact with the cavity fluid medium is very convenient to replace the valve shaft, the valve does not need to complete detachment pipeline. Fluorine butterfly valve is widely applicable to various types of industrial pipeline liquids and gases (including steam) transportation, especially the use of occasions with severe corrosive media, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, aqua regia and other strong corrosive media.
