Main performance characteristics of electric flange type hard-sealed butterfly valve
1 . Reasonable structure, small and light, flexible operation, labor-saving and convenient;
2 . Reliable sealing, can achieve air tightness without leakage;
3 . The flow characteristics tend to have the best linear regulation;
4 . Adopting the principle of triple eccentricity, the sealing surface is nearly zero damage and the service life of the valve is prolonged;
5 . Wide range of applications. Such as: can be used for water, steam , oil, air, gas and other media.
6 . Applicable to different temperatures and pressure levels below 6.4MPa, corrosion-resistant and other medium pipelines.
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.
