Product description
Flanged fluorine-lined centerline butterfly valve is a common anti-corrosion valve in modern industry. Its flow path, butterfly plate, valve stem and all parts in contact with the medium are fully lined with PTFE technology, which has good acid and corrosion resistance. Mainly used in various chemical and industrial pipelines with corrosive media. Suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants (50℃~150℃), FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosion It has good anti-corrosion performance with natural gas and liquid medium. The valve uses the top wrench or handwheel mechanism to rotate, pushing the valve stem to drive the rotation of the butterfly plate to complete the switching and adjustment of the butterfly valve.
