Description
Fluorine lined pneumatic butterfly valve
The fluorine lined butterfly valve seat and valve plate is made by the PTFE, has both the common butterfly valve mechanical strength, and also can play strong resistance to chemical medium properties of PTFE or PA. The anticorrosion performance is excellent. It is applicable to all kinds of acid、alkali 、salt and oxidant、reductant、organic solvent and other media. It is widely used in chemical industry、petroleum、medicine、food、 steel melting、the papermaking 、the water and electricity system of gases、liquids、semifluid piping and container closure and adjust equipment.
