Pneumatic Valve PVC Material Valve Body
- Designed for corrosive media
- Fluoroplastics’ high-temperature tolerance
- Suitable for automation control in strong acids, strong alkalis, high-purity fluids
The Pneumatic UPVC Butterfly Valve is a centerline-type butterfly valve driven by a pneumatic actuator, specifically designed for corrosive media. Its core components (e.g., disc, sealing rings) can be lined with fluoroplastics (e.g., FKM, EPDM, NBR), combining UPVC’s corrosion resistance with fluoroplastics’ high-temperature tolerance. Suitable for automation control in strong acids, strong alkalis, high-purity fluids, and certain high-temperature applications, it is widely used in chemical, water treatment, food and pharmaceutical industries.
