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.
