After the design of valve block is completed, the processing technology is as follows: pretreatment. The material for processing valve block shall be compact and free from interlayer, trachoma and other defects.

The hydraulic valve block is a small circuit in the process of operation. In the process of use, all kinds of used valves are connected together through the oil holes on the valve block. For example, we now use a balance valve block, which contains balance valve, pressure reducing valve, one-way valve, directional valve and shuttle valve.

The surface roughness of the valve and flange installed on the hydraulic valve block shall reach Ra0.4, and the surface roughness of the sealing surface of the end pipe joint shall reach ra3.2. In addition, the tolerance of perpendicularity between the screw hole of pipe joint and its outer joint surface shall be at least Grade 8.

After the design of valve block is completed, the processing technology is as follows: pretreatment. The material for processing valve block shall be compact and free from interlayer, trachoma and other defects. The blank shall be inspected before processing.
