Working principle of electric rubber wafer butterfly valve:
The D971X electric rubber wafer butterfly valve has a small operating torque and is the smallest operating torque among all valve types. It is the execution unit of instruments in automation control systems, powered by AC220V, AC380V, or DC24V power supply voltage. It receives (4-20mA, 0-10mA, or 1-5VDC) current or voltage signals from (DCS, PLC) systems or regulating instruments, operators, etc. to control operation. By rotating the valve shaft 0~90 º with the torque output from the angular stroke, the opening and closing action or adjustment action can be completed. The fully electronic electric actuator adopts an electromechanical integrated structure, with functions such as internal servo operation and opening signal position feedback, position indication, manual operation, etc. It has strong functions, reliable performance, simple wiring, precise control, small volume, light weight, small flow resistance, large flow coefficient, simple structure, and good sealing performance. The adjustment range is large. By inputting a current signal or a voltage signal, this is transformed into a displacement corresponding to the input signal, changing the rotation angle of the valve plate (any angle from 0 to 90 º). Therefore, a certain input signal corresponds to a certain angle, achieving proportional action. Therefore, there is a good way to adjust and control parameters such as flow.
