The invention discloses a hydraulically-controlled proportional multi-way valve with an inlet/outlet throttling edge independent adjusting function. The proportional multi-way valve comprises at leastone set of valve blocks connected with a hydraulic actuator. Each valve block comprises two three-position three-way hydraulic control proportional directional valves, two electric proportional fixeddifferential reducing valves and a pressure cutoff valve. Oil paths comprise the oil supply path P, the oil return path T and the loading oil paths A and B. After receiving an active input signal ofone certain set, a controller sends a corresponding electric control signal to the two electric proportional fixed differential reducing valves of the corresponding set according to corresponding control logic, the valve port opening degree and valve element reversing of the electric proportional fixed differential reducing valves are controlled through output pressure of the electric proportionalfixed differential reducing valves, and accordingly flow fed into or discharged out of a hydraulic cylinder and two-way action of the hydraulic actuator are controlled. The valve has various meso-position functions so as to adapt to different working conditions, the inlet and outlet direction and flow of the oil paths can be controlled independently, whether to perform throttling or not depends on the working conditions, efficiency of a hydraulic system is greatly improved, and meanwhile the requirement of a high-flow hydraulic system can be met.
