Full PTFE FEP PFA Lined motorized butterfly valve introduction:
Full PTFE FEP PFA Lined motorized butterfly valve is composed of motorized actuator and PTFE FEP PFA 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.Full PTFE FEP PFA Lined motorized butterfly valve according to different working conditions choose different lining valve body, divided into full fluorine lined butterfly valve and half fluorine lined butterfly valve, the control mode has switch off type and intelligent control type.Full PTFE FEP PFA Lined motorized butterfly valve has a tight sealing performance, and not only has the mechanical strength of the ordinary butterfly valve, but also can play the chemical characteristics of corrosion resistance, acid and alkali resistance, under general and conventional conditions, than the stainless steel valve butterfly valve has a higher cost performance.
 
Full PTFE FEP PFA Lined motorized butterfly valve Application :
Full PTFE FEP PFA Lined motorized 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, Full PTFE FEP PFA Lined motorized butterfly valve is 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.
