The fluorine-lined butterfly valve features a split-body design. Sealing at both ends of the valve shaft is achieved through the rotational base surface between the butterfly disc and valve seat, reinforced with fluororubber. This design ensures a compact structure, aesthetically pleasing appearance, rational manufacturing process, and reliable performance. It guarantees that the valve shaft remains isolated from the internal fluid medium, enabling convenient shaft replacement without requiring the valve to be removed from the pipeline.

D41/D341FS Flanged Fluoroplastic-Lined Sealed Butterfly Valves are widely applicable for conveying liquids and gases (including steam) in various industrial pipelines, particularly in applications involving severely corrosive media such as sulfuric acid, phosphoric acid, chlorine gas, strong alkalis, aqua regia, and other highly corrosive substances.
