Summary
ZDLPF46 type electronic fluorine single seat regulating valve is 381L series electronic actuator and through single seat fluorine lining valve. The actuator uses an integrated electronic controller module, no need of a servo amplifier, and the output force; body wetted parts are high-pressure injection molding process, lined with corrosion resistance, aging resistance of the fluorinated ethylene propylene (F46), and adopts Teflon bellows seal, so that the valve is widely used in chemical, petroleum, metallurgy, medicine, electricity and other industries in acid, alkali and other strong corrosive media and toxic and volatile gas, liquid medium, process control.

Characteristic
Corrosion resistance: the body cavity, valve, valve seat, stem were lining thickness 2.5 ~ 3mm F46, acid, alkali, strong corrosion resistance
Sealing performance: the use and packing double bellows sealed PTFE material, ensure no leakage
A small amount of leakage: because the valve core, the valve seat is soft seal, so leakage is lower than the national standard of the grade
