Product features

Corrosion resistant electric fluorine lined butterfly valve is composed of electric actuator and flange or wafer type fluorine lined butterfly valve. The butterfly valve seat and sealing surface are lined with fluorine plastic, which has the advantages of zero leakage, long service life, super corrosion resistance and wear resistance. The electric fluorine lined butterfly valve selects different lining valve bodies according to different working conditions, which can be divided into full lining fluorine butterfly valve and semi lining fluorine butterfly valve. The control modes include switch off type and intelligent adjustment type. The electric fluorine lined butterfly valve has a tight sealing performance, and not only has the mechanical strength of ordinary butterfly valves, but also can play the chemical characteristics of PTFE, such as corrosion resistance, acid and alkali resistance. Under normal conditions, it has a higher cost performance than the butterfly valve with stainless steel body.

Application of electric fluorine lined butterfly valve:
 
The electric fluorine lined butterfly valve is lined with a thick layer of fluoroplastic polymer material on the flow passage parts (disc plate, inner wall of valve body) that will contact with the medium, so it is also called the electric plastic lined butterfly valve. It is suitable for the transportation of liquids and gases (including steam) in various industrial pipelines, especially for the use of media with serious corrosiveness, scouring and grinding, such as sulfuric acid, hydrofluoric acid Phosphoric acid, chlorine, strong alkali, aqua regia and other highly corrosive media are not suitable for process media with particles and high temperature.
Applicable temperature of electric fluorine lined butterfly valve (℃):

1. Perfluoroethylene FEP (F46): - 85~150
2. Tetrafluoroethylene ethylene ETFE (F40): - 80 -- 220
3. Soluble tetrafluoro PFA (FA): - 70~200
4. PTFE (F4): - 200~180
5. Polyvinylidene fluoride PVDF (F2): - 70~100
6. Modified polyethylene FRPE (PO): - 58~80
Different materials are suitable for different temperatures and different media

Performance characteristics of electric fluorine lined butterfly valve:
Electric fluorine lining butterfly valve (full fluorine lining) Electric fluorine lining butterfly valve (semi fluorine lining)
 
1. The valve body can be made of stainless steel or other materials, and it is light in weight and fast in electric switch speed;
2. The sealing material of electric anti-corrosion butterfly valve has a long service life and is characterized by aging resistance, corrosion resistance, erosion resistance, etc;
3. It can be installed in any position, convenient for maintenance, and the flange to clip hole connection is applicable to various standards;
4. The sealing elements of the electric corrosion resistant butterfly valve can be replaced, and the sealing performance is reliable, which can achieve two-way sealing and zero leakage.
5. The electric anti-corrosion butterfly valve is suitable for chemical media and the upper and lower middle holes of the valve plate. It adopts a spherical friction surface design, with less torque and excellent sealing performance.
