Flange Butterfly Valve/Pneumatic Butterfly Valve/Electric Butterfly Valve
Flange rubber-lined butterfly valve has the characteristics of strong corrosion resistance, good stability, and strong reliability. It plays the role of regulating flow or intercepting media on gas and liquid pipelines. Rubber-lined butterfly valves also have the advantages of strong sealing reliability, strong anti-corrosion capabilities, and small operating torque. Therefore, flange rubber-lined butterfly valves are widely used in industries such as food, medicine, chemicals, petroleum, electricity, textile, papermaking, etc.
