<正>This paper presents the structure and working principle of counterbalance valve used in some hydraulic cranes.Based on the AMESim software,the model of the counterbalance valve is build,and the simulation analysis for its performances is done.The simulation results show that the valve has a good dynamic response performance and stability,its control spool opening is independent of the load,and the main concerned structural parameters can affect the performance of the counterbalance valve.
