Electric butterfly valves are available in two types: on-off type and intelligent type. The butterfly valve is matched with DSR actuator. It can be operated by inputting control signal (4~20mADC or 1~5VDC) and single-phase power supply.
It features powerful functions, compact size, light weight, cost-effectiveness, reliable performance, simple matching and large flow capacity. It is especially suitable for working conditions with viscous, particle-containing and fiber-laden media. At present, the valve is widely applied in industrial automatic control systems of industries including food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching & scientific research equipment, electric power and other fields.
