Polyfluortetraethylene Lining Butterfly Valve

The butterfly plate of the fluorine lined butterfly valve is installed in the diameter direction of the pipeline, and in the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation Angle is between 0° and 90°. When the disc is rotated to 90°, the valve is fully open. Fluorine lined butterfly valve is mainly composed of valve body, butterfly plate, valve seat, stem, transmission mechanism and other components, of which the valve body and the surface of the butterfly plate are lined with fluorine plastic materials, such as polytetrafluoroethylene (PTFE) and so on.

• Strong corrosion resistance: fluorine plastic materials have excellent corrosion resistance and can resist the erosion of a variety of corrosive media, such as acid, alkali, salt and so on. This makes the fluorine lined butterfly valve widely used in chemical, pharmaceutical and other industries.

• Good sealing performance: a tight sealing structure is formed between the fluoroplastic lining and the butterfly plate to ensure no leakage of the valve in the closed state. This helps to protect the safe and stable operation of the pipeline system.

• Quick opening and closing: The opening and closing operation of the fluorine-lined butterfly valve is simple and fast, usually by rotating 90° to complete the opening or closing. This helps to improve work efficiency and reduce energy consumption.

• Flow adjustment function: By adjusting the rotation Angle of the butterfly plate, the flow rate of the medium can be controlled. This makes the fluorine-lined butterfly valve highly useful in applications where precise flow control is required.
