Flanged butterfly valve is used in gas, and water supply and drainage pipeline to control flow in food processing, medical factory, chemical plant, power station, construction, and paper making fields, etc. The sealing pressure is 1.0MPa for DN50-DN800 series control valve, and 0.6MPa for DN900-DN1200 series. Dimension for valve connection is designed according to the standards of 1.0MPa. For any special requirements please let us know.
1. Our flanged butterfly valve is of unique design, reasonable structure, light weight, and quick closing and opening.
2. With small operating torque, the valve is rather easy operated.
3. The butterfly valve can be mounted at any places in a pipeline. Maintenance operation is easy.
4. The sealing device is replaceable. The 2-way sealing mechanism allows for zero leakage.
5. We have specially adopted sealing materials with high corrosion-resistance and long service life.
