In this study, we develop a model of an open center and load-sensing system and for a main control valve to analyze system characteristics and efficiency using SimulationX. In order to analyze the operating characteristics of the pressure and flow of the main control valve of an open center system, a test was performed at each port. The reliability of the model was confirmed by comparing the similarity of the analysis results with the test results before analyzing the operating characteristics of the system. Development of the load sensing main control valve was performed by adding a flow sharing valve and a notched shape to the open center system based on it's the proven reliability. The authors performed the simulation under the same load conditions in order to compare the efficiency of the systems. Additionally, the combined operation performance was investigated by means of analyzing the characteristics of flow distribution under different load conditions.
