Imported electric fluorine-lined butterfly valves (D971F46, D941F46, D971F4, D941F4) are composed of electric actuators, flanges or clamp-on fluorine-lined butterfly valves. The butterfly valve seat and sealing surface are lined with fluoroplastic, which has the advantages of zero leakage, long service life, strong corrosion resistance and wear resistance.
The imported electric fluorine-lined butterfly valve selects different lining valve bodies according to different working conditions, which are divided into full-lined fluorine-lined butterfly valves and semi-fluorine-lined butterfly valves. The control modes include switch, cut, and intelligent adjustment. The electric fluorine-lined butterfly valve has tight sealing performance, which not only has the mechanical strength of ordinary butterfly valves, but also gives full play to the corrosion resistance and acid and alkali resistance of PTFE. Under general conventional conditions, it is more cost-effective than butterfly valves with stainless steel bodies.
Imported electric fluorine-lined butterfly valves (D971F46, D941F46, D971F4, D941F4) Applications:
Electric fluorine-lined butterfly valve is a thicker fluoroplastic polymer material, lined in the overflow parts (disc plate, valve body wall) in contact with the medium, so it is also known as electric plastic-lined butterfly valve, suitable for transporting liquids and gases (including steam) in various industrial pipelines, especially in the case of serious corrosive, flushing and grinding media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia and other corrosive media, but not suitable for particles and high-temperature process media.
Imported electric fluorine-lined butterfly valve (D971F46, D941F46, D971F4, D941F4) Performance characteristics:
1. The valve body is made of stainless steel and other materials, which is light in weight and fast in electric switching
2. The sealing material of the electric anti-corrosion butterfly valve has a long service life, and has the characteristics of aging resistance, corrosion resistance, and erosion resistance
3. It can be installed in any position, easy to maintain, and the flange is suitable for a variety of standards
4. The seals of the electric corrosion-resistant butterfly valve can be replaced, the sealing performance is reliable, and the two-way sealing can achieve zero leakage.
5. The electric anti-corrosion butterfly valve is suitable for chemical media, the upper and lower holes of the valve plate, and adopts a spherical friction surface design, with small torque and excellent sealing performance.
