FIG228F Fluorine-Lined Butterfly Valve with Polished Disc, XSTOU Pneumatic Fluorine-Lined Butterfly Valve is a regulating valve with a simple structure, easy operation, long service life, and lightweight design. It can be used for both on/off and regulating applications. Suitable for controlling gases, liquids, slurries, solid powders, and other fluids in industries such as chemical, pharmaceutical, food, papermaking, and water treatment.

FIG228F Fluorine-Lined Butterfly Valve with Polished Disc, XSTOU Pneumatic Fluorine-Lined Butterfly Valve Performance Characteristics
1. The valve interior and disc are lined with polytetrafluoroethylene (PTFE), isolating the medium from the valve body to achieve corrosion resistance.
2. Under conventional conditions, it can replace stainless steel valve bodies, offering higher cost-effectiveness. The butterfly disc is installed along the diameter direction of the pipeline.
3. In known butterfly valve technologies, the sealing form mostly adopts a sealing structure with materials such as PTFE. Due to structural limitations, it is not suitable for industries requiring high temperature, high pressure, corrosion resistance, or wear resistance.
Product Advantages
1. Excellent chemical stability, high heat resistance, cold resistance, and low friction coefficient, making it an ideal self-lubricating material.
2. Suitable for pipelines handling strong alkalis, organic solvents, and other corrosive gases or liquid media of various concentrations.
3. The F46 lining material can withstand temperatures up to 140°C, while the PFA lining material can withstand temperatures up to 200°C.
