Fluorine-Lined Pneumatic Ball Valve

Fluoroplastic-lined pneumatic ball valves feature fluoroplastic linings and precision investment-cast housings, offering high strength and a smooth finish. All wetted parts are made of fluoroplastic, enabling these valves—including fluoroplastic-lined and PTFE-lined pneumatic ball valves—to operate continuously within the temperature range of -50°C to 180°C in corrosive pipelines and conduits carrying any concentration of corrosive fluids.
