Electric butterfly valve is a kind of high efficiency butterfly valve driven by electric actuator to realize automatic control, which is widely used in petroleum, chemical industry, electric power, metallurgy, pharmacy, water supply and drainage and environmental protection and other working condition environments. The valve is suitable for water, steam, air, oil and various corrosive media, with excellent sealing performance and corrosion resistance. The electric butterfly valve realizes precise opening and closing control through electric actuator, with fast response and easy operation, supports remote monitoring and intelligent system integration, and meets the demand of modern industrial automation. The product has compact structure, small flow resistance, stable opening and closing, strong pressure resistance, convenient maintenance and long service life. Electric butterfly valve not only realizes efficient cut-off and flow regulation of medium, but also improves the automation level and operation efficiency of the system through intelligent control. Its high performance and reliability make it an important valve equipment in all kinds of industrial processes, widely used in automated piping systems for fluid control and management.
