Main performance characteristics
- Reasonable structure, small and lightweight, flexible operation, labor-saving and convenient;
- Reliable sealing, which can achieve air sealing without leakage;
- Flow characteristics tend to be linear and have good adjustment The best;
- The principle of triple eccentricity is adopted, so that the sealing surface is nearly zero and the service life of the valve is prolonged;
- The application range is wide. Such as: can be used for water, steam , oil, air, gas and other media.
- It is suitable for various medium pipelines such as different temperatures and pressure levels below 6.4MPa, corrosion resistance and so on.
Application of electric flange type hard sealing butterfly valve
This butterfly valve is suitable for food, medicine, petrochemical, power plants, steel mills, industrial environmental protection water treatment and high-rise buildings, water supply and drainage pipelines as devices for regulating flow and shutting off fluids.
