China Wave Hard Seal Butterfly Valve Manufacturers, Suppliers and Factory with High Quality
1.Introduction of Wave Hard Seal Butterfly Valve
Wave hard seal butterfly valve adopts "U" type stainless steel sealing ring, the valve body adopts three eccentric multi-level metal sealing structure, and the precise valve plate sealing surface is organically combined with three-dimensional eccentric sealing surface after polishing. It has the characteristics of high and low temperature resistance, high pressure, allowing medium to have small particles, long service life and so on. Wave hard seal butterfly valve can be widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage pipelines.

3.Advantages of Wave Hard Seal Butterfly Valve
1) Wave hard seal butterfly valve adopts three eccentric seal structure, and the valve seat and butterfly plate are almost free of wear;
2) The washer hard seal butterfly valve is made of stainless steel, which has the double advantages of metal hard seal and elastic seal. It has excellent sealing performance and long service life in both low and high temperature;
3) The sealing surface of wafer hard seal butterfly valve is overlaid with cobalt based cemented carbide, which is wear-resistant and has long service life;
4) Wave hard seal butterfly valve large size butterfly plate adopts quilting structure, with high strength, large flow area and small flow resistance;
5) The wave hard seal butterfly valve has the function of two-way sealing. It can be installed in any direction without the restriction of medium flow direction or the influence of space position;
6) The wave hard seal butterfly valve drive can rotate 90 degrees in multiple positions ° Or 180 ° Installation, easy for users to use.
