Working principle of electric rubber flange butterfly valve

Working principle of electric rubber flange butterfly valve:

D941X electric rubber flange butterfly valve is composed of angular travel electric actuator (0~90° partial rotation) and soft seal butterfly valve through mechanical connection, after installation and debugging. According to the action mode, there are: switch type and regulator type. Switch type is directly connected to the power supply (AC220V or other power supply grade) through the switch positive, anti-conduction to complete the switching action. Regulating type is based on AC220V power supply as the power, receive industrial automatic control system preset parameter value 4~20mA (0~5 and other weak current control) signals to complete the adjustment action.
