The electro-hydraulic digital control technology has gradually become an important development direction to realize electro-hydraulic integration, the development of new digital flow valves, digital pressure valves and digital direction valves is particularly important. At present, most of the digital valves on the market are single-stage valves driven by digital units. But the flow capacity of them is limited, and it is difficult to meet most requirements. A new mechanical structure of double direction valve was put forward, which used the mechanical feedback principle, making digital valve main valve core could follow the guide valve core displacement and movement through the role of the hydraulic oil pressure. The pilot valve was driven by the common digital component stepper motor so as to achieve the digital control of the whole two-stage directional valve.The feasibility and effectiveness of this structure were verified through relevant simulation analysis.It provides reference for the development of similar product structure design.
