FLE-Q-F PTFE Fluorine-Lined Electric Ball Valve
FLE-Q-F PTFE Fluorine-Lined Electric Ball Valve
Fleyenda two-way PTFE fluorine-lined ball valve has GB/DIN/ANSI/JIS standards. The valve body is lined with imported fluorine material, which has good corrosion resistance and wear resistance. The valve body is compact in design and has small gaps, which effectively reduces the accumulation of materials and prevents the crystallization of accumulations from affecting the sealing effect. Suitable for highly corrosive media such as alkali salt, oxidative extrusion, sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, etc.
PTFE Fluorine-Lined Electric Ball Valve – Key Features
PTFE (or FEP/PFA) lining ensures superior resistance to strong acids, alkalis, and corrosive chemicals
Electric actuator control enables automated on/off or modulating operation
Zero-leakage sealing with precision-machined ball and seat design
Full-bore flow path minimizes pressure drop and maximizes efficiency
Robust body materials (carbon steel, stainless steel) fully protected with fluorine lining
Actuator options: ON/OFF, modulating (4–20mA / 0–10V), with position feedback and manual override
Ideal for chemical, pharmaceutical, petrochemical, environmental, and water treatment industries
