FLE-Q-F Fluorine Lining Motorized Ball Valve

FLE-Q-F Fluorine Lining Motorized Ball Valve

Fleyenda FLE-Q-F Fluorine Lining Motorized Ball Valve is a two-way PTFE-lined valve built to GB, DIN, ANSI, and JIS standards. Its compact body design with minimal gaps reduces material buildup and crystallization, ensuring reliable sealing. Made with imported fluorine material and stainless or carbon steel body, it provides excellent corrosion and wear resistance. Suitable for highly corrosive media such as alkali salts, sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, and oxidative chemicals. Size range: 1/2”–4”, temperature -10°C to 180°C, operating pressure up to 16 bar.

FAQs That 80% Users Interest

• The Fluorine Lining Motorized Ball Valve uses PTFE or PFA materials that isolate corrosive media from metal surfaces, providing strong resistance to acids, alkalis, and chlorine-based compounds.
• The electric actuator enables precise remote operation, reducing manual contact with hazardous fluids and ensuring stable torque output.
• Compared with standard stainless valves, the fluorine-lined ball valve offers longer service life and reduced maintenance downtime, improving process efficiency.

• A high-quality PTFE-lined motorized valve operates steadily up to about 120 °C and 16 bar, suitable for most chemical and wastewater systems.
• PFA-lined valves resist deformation during rapid heating or cooling cycles, maintaining consistent sealing.
• Matching media conditions with lining specifications prevents blistering or delamination, ensuring reliable long-term use.

• Common causes include misaligned installation, negative pressure, or abrasive particles damaging the fluorine lining.
• Correct flange alignment and proper wiring prevent actuator overload and leakage.
• Ensuring medium compatibility and correct torque settings significantly extends valve life and reliability.

• The motorized ball valve provides full-port flow and tighter shutoff, ideal for corrosive or viscous fluids.
• The fluorine lining offers superior chemical resistance where solenoid valves would corrode quickly.
• Solenoid valves switch faster for light-duty use, while electric-actuated fluorine-lined valves perform better in heavy chemical or process control systems.

• Inspect actuator housing and flange joints regularly for leaks or discoloration.
• Cycle the valve periodically to prevent seat adhesion and maintain actuator performance.
• Record operating hours, media type, and temperature to predict maintenance needs.
• Use compatible gaskets to protect the PTFE-lined body from chemical attack.
