Pneumatic PTFE lined butterfly valve introduction
Pneumatic PTFE lined butterfly valve is full PTFE or PFA lined body and disc for corrosive medium.The connection end can be wafer,lug or flange type..Pneumatic PTFE lined butterfly valve can be easily installed and maintained in any location.The sealing element can be replaced, and the sealing performance is reliable to achieve zero leakage of two-way sealing, the sealing material is resistant to aging, corrosion and long service life.

Pneumatic PTFE lined butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of qianthermal power station.
