First, the electric flanged butterfly valve seal structure and performance Introduction
 The product from the valve body, disc, seals, transmission and other major components. The structure of the three-dimensional design of the eccentric principle, flexible sealing and multi-layer seal compatible with flexible processing of new technology so that the butterfly valve in operation, reducing its torque, to save energy and energy-saving features. Thus ensuring the overall corrosion resistance. High temperature. , Anti-extravagant reliability. 
 
 Second, the electric flanged hard-sealing butterfly valve main performance characteristics
 1, the structure of a unique, small and lightweight, flexible operation, labor-saving and convenient; 
 2, sealed and reliable, can be sealed without leakage; 
 3, flow characteristics tend to rectilinear Best; 
 4, the use of three eccentric principle, so that the sealing surface is almost zero loss extended valve life; 
 5, a wide range of applications. Such as: can be used for water, steam, oil, air, gas and other media. 
 6, for different temperatures and pressure levels below 6.4MPa, corrosion and other media pipeline. 
 
 Third, the use of electric flanged butterfly valve
 This butterfly valve is suitable for food, medicine, petrochemical, power plants, steel mills, industrial water treatment and high-rise building environmental protection, water supply and drainage pipe for regulating flow and cut off the best fluid device.
