The invention relates to an electromagnetic proportional valve capable of resisting flow saturation. The electromagnetic proportional valve is characterized in that the electromagnetic proportional valve comprises a valve block, a reversing valve core, a left pressure compensated valve core and a right pressure compensated valve; an upper axial hole and a lower axial hole are formed in the valve block; a first flow channel, a second flow channel, a third flow channel and a fourth flow channel communicate; a pressure oil port, a first working port, a second working port, an oil return port anda loading pressure feedback port are formed in the valve block; the reversing valve core is driven by an electromagnetic driving structure so as to be able to slide leftwards and rightwards; an annular middle part through-flow groove, a left through-flow groove and a right through-flow groove are formed in the periphery of the reversing valve core; and the left pressure compensated valve core andthe right pressure compensated valve are arranged at the upper axial hole in a left-right spaced manner and can slide. The electromagnetic proportional valve has a flow saturation resisting function and integrates multiple hydraulic valves in one valve block, and oil ducts are few and are distributed regularly, so that machining is facilitated; in addition, a structure is more compact, disassemblyand assembly are facilitated; the valve cores move stably; operating performance of a vehicle or an engineering machine using the electromagnetic proportional valve is improved greatly, and phenomenaof excessive rapidness at a low load and stopping at a high load are avoided.
