In the layout, we should consider whether the installation direction of the valve body is reasonable. We should make the spool in the horizontal direction to prevent the self weight of the spool from affecting the sensitivity of the valve, especially the directional valve must be arranged horizontally.

The importance of hydraulic valve block in hydraulic system has been recognized by more and more people, and its application scope is more and more extensive. The use of hydraulic valve block can not only simplify the design and installation of hydraulic system, but also facilitate the integration and standardization of hydraulic system, reduce manufacturing cost, improve accuracy and reliability.

Hydraulic valve block processing difficulties solution: Tooling Design: the intersecting holes can be processed on the vertical machining center with rotating shaft, so as to reduce the number of workpiece clamping and solve the angle problem of inclined hole.

The hole diameter in the valve block should match with the flow rate, especially the through hole must have enough flow area, the direction and position of the oil inlet and outlet should match with the general layout of the system and the connection form of the pipeline, and the process of installation operation should be considered. The components with vertical or horizontal installation requirements must meet the requirements after installation.
