The centerline flange butterfly valve is suitable for regulating the flow rate and intercepting media of water supply, drainage, and gas pipelines. Food, chemical, petroleum, electricity, textile, papermaking, etc., temperature ≤ 120 ° C, nominal pressure ≤ 1.6MPa.  

Function of centerline flange butterfly valve:

1. The centerline flange butterfly valve has a novel and reasonable design, unique structure, light weight, and fast opening and closing.   

2. Small operating torque, easy to operate, labor-saving, and intelligent.   

3. Can be installed and maintained at any location.   

4. The seal is replaceable, and the sealing performance is reliable to achieve bidirectional sealing with zero leakage.   

5. The sealing material is resistant to aging, corrosion, and has a long service life.
