According to the analysis on the working principle of the load-sensing hydraulic system with multi-way valve and constant-difference relief pressure-compensated valve in the load-sensing circuit, it is concluded that there are two working conditions during the operation of the system, load-sensing condition and constant pressure supply condition. Without considering the effect of balance valves, the load boundaries of the forward and backward motion of two conditions were derived, as well as the whole load boundary. The selection principle of balance valves was studied and analyzed to expand the load boundaries. The above conclusions can be applied to this type of load-sensing hydraulic system with any valve-controlled cylinder structure and also provide the theoretical guidance for the design and apply of the system.
