Electric epoxy coated PTFE butterfly valve

Electric epoxy coated PTFE butterfly valve

The electric PTFE butterfly valve uses the butterfly plate that rotates with the valve stem as the opening and closing part to realize the opening, closing and adjustment of the valve. The electric fluorine-lined butterfly valve is a thick polymer material with lining technology on the overflow parts, valve body, disc, and valve stem, and has excellent corrosion resistance. It is an ideal product for intercepting and regulating equipment on gas, liquid and semi-fluid pipelines and containers in chemical, petroleum, pharmaceutical, food, iron and steel smelting, papermaking, hydropower and other systems, and can replace Gate valves, globe valves and other types of shut-off and regulating valves.
