In this paper, the topic is focused on operating principle and system characteristics of LUDV load sensing system with downstream compensator of valvel, and the simulation models of load sensing system and downstream compensator of valve which are widely used in the engineering machinery as a classic using are built, then, the influ-ence of performance caused by different key characteristic parameters in the condition of saturation and under-satura-tion is analyzed by modeling and simulating the load sensing system with downstream compensator of valve. And then, the system performance characteristics is also obtained, and the system characteristics, in the case of non-satu-ration flow rate, is analyzed, which offers technique support for the load-sensitive system designing.
