The numerical simulation of a 3-D model of the internal flow field for a U-shaped slide valve has been analyzed in this paper. The impact of different opening degree on the pressure and velocity were analyzed. The results show that in the U-shaped groove, the pressure changes rapidly, and in the outlet oil chamber, the vortex was appeared. According to the expression of the flow coefficient, the flow characteristic was predicted by CFD, the conclusions show that with the increase of opening degree, the flow gradually increases, and the flow coefficient was not a stable value.
