The fluorine lined gate valve is a corrosion‑resistant industrial valve designed for on‑off control of aggressive media. Its gate moves perpendicular to the flow direction, allowing only full open or full close operation—no throttling. Key features include low fluid resistance, minimal erosion of sealing surfaces, and bidirectional flow capability. The valve body and trim are lined with fluoropolymer materials (such as PTFE, PFA, FEP, or PO), providing excellent chemical resistance.
