Imported electric butterfly valves are usually composed of an angle stroke electric actuator (0-90 ° partial rotation) and the butterfly valve as a whole, which are mechanically connected and installed and debugged together. Electric butterfly valves mainly include electric butterfly valves, electric regulating butterfly valves, electric explosion-proof butterfly valves, electric ventilation butterfly valves and other series. Electric butterfly valves, electric regulating butterfly valves, electric explosion-proof butterfly valves, and electric ventilation butterfly valves are directly connected to the power supply (AC220V or other power supply levels) to complete the switching action through the forward and reverse direction of the switch. The electric regulating butterfly valve is powered by an AC220V power supply and receives a parameter value of 4-20mA (0-5 weak current control) signal preset by the industrial automation control system to complete the regulating action.
