Butterfly valve growth history
Dec 02, 2016

Because PTFE has strong corrosion resistance, stable performance, not easy to aging, low coefficient of friction, easy to be formed and dimensionally stable, and can be filled and added appropriate materials to improve its comprehensive performance, get better strength, Lower coefficient of friction butterfly valve sealing material, to overcome the limitations of synthetic rubber, and thus PTFE as the representative of the polymer materials and filled with modified materials in the butterfly valve has been widely used, so that the butterfly valve Performance has been further improved, there has been temperature, a wider range of pressure, sealing performance, longer life of the butterfly valve. To meet the high and low temperature, strong erosion, long life and other industrial applications require the past decade, the metal seal butterfly valve has been greatly developed. With the high temperature, low temperature resistance, strong corrosion resistance, strong erosion resistance, high strength alloy materials in the application of butterfly valve, the metal sealing butterfly valve in high and low temperature, strong erosion, long life and other industrial fields has been widely used, (9750mm), high pressure (2.2kN / cm2), wide temperature range (-102 ~ 606 ℃) butterfly valve, so that the butterfly valve technology to a whole new level.
