Fluorine Lined Ball Valves 15-200mm DN Size with 1.0-2.5 MPa Pressure Rating for Corrosive Media
Highly resistant to acids and alkalis, these manual operational ball valves feature fluorine plastic lining for exceptional corrosion resistance in demanding industrial applications.
Fluorine lined ball valves utilize the operational principles of standard ball valves while incorporating advanced fluorine plastic lining and precision investment casting for the shell. This construction provides superior strength, smooth surface finish, and complete corrosion protection as all liquid-contact components are manufactured from fluorine plastic materials.
Designed for continuous operation in temperatures ranging from -20°C to 180°C, these valves handle corrosive media of any concentration. The pneumatic version enables automated opening and closing control for highly corrosive pipeline systems.
