Electric Actuated High Performance Butterfly Valve
Electrically high-performance butterfly valves are usually composed of a quarter-stroke electric actuator (0~90° partial rotation) and the butterfly valve as a whole through mechanical connection, after installation and debugging. According to the active mode, there are switch type and regulating type. The switch type is directly connected to the power supply (AC220V or other power supply levels) to complete the switching action by switching the positive and negative directions.
Regulating type is powered by AC 220V power supply and receives 4~20mA (0~5 weak current control) signal preset by the industrial automation control system to complete the adjustment action.
