LUG TYPE BUTTERFLY VALVE

MAIN FEATURES:

American standard lug butterfly valve is a new generation of high performance products in our company engineering technicians research and development, its performance has already reached the domestic and international advanced level. American standard lug butterfly valves are widely used in the pipeline of low pressure, medium pressure, high pressure, steel metallurgy, petroleum, chemical, electric power industries for cutting off or regulatory medium in flow. American standard lug butterfly valve is by three d eccentric inclined conical seat sealing butterfly plate seal, new metal with elastic material, and a cascade of embedded into the butterfly plate and seat identical. American standard lug butterfly valve structure characteristics ruled out other types of butterfly valves beyond open and the shortcomings of unsealing, and overcome the other type valves in high temperature easy to leakage faults. American standard lug butterfly valve according to use media requirements, choose different material, in order to ensure the sealing surface sealing surface wear resistance, corrosion resistance, long
