Abstract: Digital high speed on off valve is used in the article as priority valve to make up of digital electro hydraulic proportional directional valve,which fulfills digitized control of working device for loader.Mathematical model and control law of the digital electro hydraulic proportion system are put forward.Furthermore,computing simulation and experimental verification are carried out.

Key words: loader, high speed on off valve, digital electro hydraulic proportion system
