The present invention relates to a proportional valve for controlling fluid-flow direction, flow rate and pressure, and is characterized by that it adopts the multi-stage combined bidirectional active numerically-controlled electromagnet group to raise starting electromagnetic force, and eliminates or reduces the rigidity of back spring, reduces driven component and eliminates their gap so as to raise the response speed of said proportional valve. Said invented proportional valve is low in energy consumption, small in valve body size, light in weight, low in cost, strong in contamination resistance and its response performance is close to that of servo valve, and under the condition of direct-acting mode and large flow rate, it can implement quick response proportional control for flow rate or pressure (when 100L/min, it is 170Hz, and when 300L/min. it is 100Hz).
