Electric Fluorine Butterfly Valve

Electric Fluorine lined butterfly valve of overview:

Electric fluorine lined butterfly valve is composed of electric actuator and flange or sandwich-type fluorine lined butterfly valve, butterfly valve seat and sealing surface lined with fluorine plastic, with zero leakage, long life and super corrosion resistance and wear resistance and other advantages. Electric fluorine lined butterfly valve according to different working conditions to choose different lining body, divided into full fluorine lined butterfly valve and half fluorine lined butterfly valve, control mode has switch cut off type and intelligent control type. Electric fluorine lined butterfly valve has a tight sealing performance, and not only has the mechanical strength of ordinary butterfly valve, but also can play the corrosion resistance, acid and alkali resistance chemical characteristics of PTFE, in general and conventional working conditions, than the butterfly valve of stainless steel body has a higher cost performance.

Electric fluorine lined butterfly valve of application:

Electric fluorine-butterfly butterfly valve is in contact with the medium flow components (disc plate, valve body wall) lining on a thicker layer of fluorine plastic polymer material, so also known as electric chensu butterfly valve, suitable for all kinds of different industrial liquid and gas in the pipeline transportation (including steam), especially with severe corrosion, erosion, hone medium the use of occasions, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali and aqua regia has strong corrosive medium, but does not apply to medium particles and high temperature process.

Performance characteristics of electric fluorine lined butterfly valve:

1. The valve body is optional with stainless steel and other materials, light weight and fast electric switching speed;

2. The electric anticorrosive butterfly valve sealing material has a long service life and is anti-aging, anti-corrosion and anti-scouring.

3, can be installed in any position, easy to maintain, flange clamp hole connection applicable to a variety of standards;

4, electric corrosion resistant butterfly valve seals can be replaced, the sealing performance is reliable, can achieve two-way sealing zero leakage.

5, electric anti-corrosion butterfly valve is suitable for chemical medium, valve plate upper and lower hole, using ball friction surface design, less torque force, excellent sealing performance.
