Concentric wafer type PTFE lined butterfly valve adopts lining technology on the flow passage parts, valve body, valve disc, valve stem. All those parts are lined with thick PTFE material, which has excellent corrosion resistance and can be applied to any concentration of acid, alkali, salt and oxidant, reducing agents, organic solvents and other mediums. Concentric wafer type PTFE lined butterfly valve is an ideal valve for shutting off and regulating equipment on pipelines and containers of chemical, petroleum, pharmaceutical, food, steel, smelting, and paper making.
