Fluorine lined flange butterfly valve

FEATURES

• Small size and light weight: The fluorine lined flange butterfly valve has a small size and light weight, making it easy to install and maintain.
• Easy to operate: Easy to operate, suitable for frequent operations.
• Excellent sealing performance: Adopting a soft sealing structure, it has excellent sealing performance and can achieve zero leakage.
• Strong corrosion resistance: The valve body is lined with fluoroplastic material (Usually polytetrafluoroethylene), which can effectively resist the erosion of corrosive media such as acid, alkali, salt, etc.
• Long service life: Due to the use of high-quality lining materials and good sealing design, the service life is relatively long.
• Simple structure: The structure is simple, the switch is fast, and only 90 ° rotation is needed to open and close.
