The multi-layer elastic seal corrosion-resistant electric butterfly valve independently developed by our company is mainly suitable for steel, cement, chemical industry, metallurgy, thermal power plants and other plants with automatic regulation of medium flow in the pipeline. The valve has good sealing performance, small air leakage rate, novel structure, tight closing, flexible opening and closing, and high temperature resistance. The valve seal is composed of multi-layer elastic stainless steel. The seal is corrosion-resistant, high temperature resistant, resilient and deformation free. It is used in chemical industry, petrochemical industry, flue gas desulfurization and denitrification, reliable and convenient for maintenance.
