Taking the multi--directional valve as the research object, this paper analyzed the working principle and structure features of the valve, and the state equations of the multi-directional valve were built by using the pressure-flow equation, flow continuity equation and valve spool force balance equation, then the static and dynamic characteristics of the valve were simulated by using the Fourth-Order Runge-Kutta algorithm in the software Matlab/Simulink. Based on the test platform of closed center load-sensing hydraulic system, experimental study of the multi-directional valve were conducted, results showed that pressure loss of the whole hydraulic system was about 1.5MPa. During step changes of the displacement of valve spool, the pressure shock of multi directional valve was small and the response characteristics were good. In addition, the function of load compensation can be realized under the step changes of load pressure, meanwhile, the system flow rate was only concerned with the opening size of the flow control orifice in the multi-directional control valve, so it had a good speed regulating performance without being affected by load variations. The multi-directional valve can meet the requirements of heavy tractor electro-hydraulic hitch.
