ZDLPF46 electronic electric fluorine lined corrugated pipe regulating valve
Product Model: ZDLPF46 Product Features: ZDLPF46 Electronic Electric Fluorine lined Bellows Regulating Valve
Product details
ZDLPF46 electronic electric fluorine lined corrugated pipe regulating valveIt is composed of a 381L series electronic actuator and a straight through single seat fluorine lined valve. The actuator adopts an integrated electronic controller module, which does not require additional servo amplifiers and has a high output force; The parts of the valve body that come into contact with the medium are all treated with high-pressure injection molding technology, lined with corrosion-resistant and anti-aging polytetrafluoroethylene (F46), and sealed with polytetrafluoroethylene corrugated pipes. Therefore, this valve is widely used in industries such as chemical, petroleum, metallurgy, pharmaceuticals, and power for process control of highly corrosive media such as acids and alkalis, as well as toxic and volatile gases, liquids, and media.
characteristic
Corrosion resistance: The valve body cavity, valve core, valve seat, and valve stem are all lined with 2.5-3mm thick F46, which can resist acid, alkali, and strong corrosion
Good sealing performance: The corrugated tube and packing made of polytetrafluoroethylene material are double sealed to ensure no leakage
Low leakage rate: Due to the soft sealing of the valve core and seat, the leakage rate is lower than the national level IV standard
