PTFE Lined butterfly valve body is divided into integral type and split combined type. According to the customer's needs, it is overall cost-effective. The split type is both assembled and sealed. When the valve is working, the PTFE valve seat and the PTFE -lined plastic butterfly plate are in contact with the medium. The inner surface of the valve body channel is smooth, the fluid damping volume is small, the CV value is high, the flow capacity is strong, the waveform is moderate, and it completely achieves zero leakage of the medium. The valve is small in size, light in weight, compact in structure, quick to open and close, beautiful in appearance, and has reasonable technology. Reliable performance, easy operation and long follow-up.

Lined Material : PTFE, FEP, PFA, GXPO etc

Connetction type : Lug butterfly valve , wafer butterfly valve ,Flanged butterfly valve

PTFE lined  butterfly valves are suitable for various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, and strong oxidants at -50°C to 150°C. FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosive substances. Used on pipelines of gas and liquid media, it has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower etc.
