NNT electric proportional valve is based on the size of the control signal to adjust the cross-sectional area of the spool. So as to achieve the process objectives and requirements of adjusting the pressure. The flow control of electric proportional valve can be divided into two kinds. One is on-off control, and the other is continuous control. The difference between servo valve and other valves is that its energy loss is greater, because it needs a certain flow to maintain the front stage control oil circuit.
