The invention provides a modularized electrohydraulic multi-way valve adopting a novel combined slide valve and compact type two way cartridge valves. The modularized electrohydraulic multi-way valve is characterized in that two reversible controlled chambers of a double-acting hydraulic cylinder or a hydraulic motor are controlled by a combined three-side slide valve main stage in one group and cartridge valve seat valve main stages of two compact type two way cartridge valves with functions of oil replenishing and various pressure controlling in one group. The modularized electrohydraulic multi-way valve can be widely applied to various machines, equipment and projects based on electric-hydraulic control loop combinations in mobile hydraulic (MH) and industrial hydraulic (IH) and control spaces having several special requirements or special purposes on environments, and a novel technological approach is mainly provided for constructing product schemes more meeting and conforming to novel diversified requirements of current mobile machinery on hydraulic technology according to users' requirements and through features that modularization is supportive of assembly and open.
