The design of the hydraulic valve is mainly for the design of the hydraulic valve group, and the oil circuit must be considered before the design of the hydraulic valve group. It is necessary to determine in advance which parts of the oil circuit can be integrated. The design of the oil circuit must be simple and save Go unnecessary steps. After determining the oil circuit, the main thing is the oblique hole and the process hole. These things in the oil path should be reduced. As long as it is enough, it
is not necessary too much. Pay attention to the hole diameter in the design of the oblique hole and the process hole.
