In this study, we develop analytical model of the load-sensing valve and analyze the system characteristics. In order to analyze characteristics of the pressure and flow and flow sharing of the load-sensing valve, test was performed on valve and vehicle. The authors studied the reliability of the analysis model by confirming the similarity of the analysis results and the test results before analyzing the characteristics of the system. Under the vehicle load conditions, The authors was performed evaluating effectiveness of the specific operation of the excavator.
