There are two kinds of electric butterfly valves: switch type and intelligent type. Butterfly valve is matched with DSR actuator, which can be controlled by inputting control signal (4~20mADC or 1~5VDC) and single-phase power supply. It has strong function, small volume, easy to carry, reliable performance, simple matching and large circulation capacity, and is especially suitable for occasions where the medium is viscous and contains particles and fibers. At present, the valve is widely used in industrial automatic control systems in food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and research equipment, electric power and other industries.
