This paper establishes the idea of a pressure reducing valve with an F-π bridge hydraulic resistance network as its pilot circuit under the theory of π bridge hydraulic resistance networks. It analyzes the working principle of the valve and establishes the nonlinear equations of flow pressure through the hydraulic resistances and force balance between the pilot and main valves. It derives the analytical expression for steady flow pressure of the F-π bridge electro-hydraulic proportional pressure reducing valve and then determines that the override pressure of the F-π bridge electro-hydraulic proportional pressure reducing valve is 0.0037% of the traditional type. A simulation shows that the flow pressure of the F-π bridge electro-hydraulic proportional pressure reducing valve is related to the hydraulic resistances of the pilot circuit and is more stable than the traditional electro-hydraulic proportional pressure reducing valve.
