The invention is to provide a modular combined electro-hydraulic multi-way valve system using compact two-way cartridge valves. Two sets of seat valve main stages including two compact two-way cartridge valves separately are used to control two reversible controlled cavities, a cartridge pressure compensation control assembly is used to control load compensation, and valve body forms the main part of electro-hydraulic multi-way valve; The main body has the function of self-supply-oil pilot control by two side flange control plates; The main part of electro-hydraulic multi-way valve, side flange control plates, pilot stages and auxiliaries combine sandwich self-supply-oil high-voltage electro-hydraulic multi-way valve reversing league with four main ports P, T, A, B and multiple control ports Pc, Tc, Ls and auxiliary ports; The system can satisfy the requirements of higher efficiency, energy saving, low emission and diversity raised by equipment manufacturers through more kinds and more reasonable modular combined configurable solutions.
