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.

Components and key components that need frequent maintenance, such as proportional valve and servo valve, shall be located above or outside the valve block for easy disassembly. In addition, a sufficient number of pressure measuring points should be set in the valve block design for the valve block adjustment.
