Product Details
Main features and applications of electric fluorine lined butterfly valve:
D971F46Electric fluorine lined butterfly valveFully lined PTFE (F4), PTFE (F3), and PTFE (F46) fluoroplastic lined valves have the advantages of corrosion resistance, no leakage, and long service life. Suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing media or high-temperature sulfuric acid, high-temperature concentrated acetic acid, acid-base alternation, various organic solvents and other strongly corrosive media. Its characteristics are as follows:
1. The design is innovative, reasonable, structurally sound, lightweight, and quickly opens and closes.
2. Small operating torque, easy to operate, labor-saving and agile.
3. Can be installed in any position, easy to maintain.
4. The seals can be replaced, and the sealing performance is reliable, achieving bi-directional sealing with zero leakage.
5. The sealing material has the characteristics of aging resistance, corrosion resistance, and long service life.
