PRODUCT OVERVIEW

Flanged fluorine-lined butterfly valve is a common anticorrosion valve in modern industry. Its flow path, butterfly plate, valve stem and all parts in contact with the medium adopt full-lined tetrafluoride process, which has good acid and corrosion resistance. It is mainly used in various chemical and industrial pipelines with corrosive media. It is suitable for (50 ~150 C).Various concentrations of aqua regia, sulphuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids and strong oxidizers, FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosive gases and liquid media, with good corrosion resistance. The valve uses top wrench or handwheel mechanism to rotate, which promotes the rotation of the valve stem to drive the butterfly plate to complete the switch and adjustment of the butterfly valve.
