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 high pressure valve block shall be made of 35 forged steel as far as possible, and the general valve block shall be made of A3 steel or ductile iron. When cutting the valve block material from the plate by gas cutting, sufficient machining allowance shall be left, and the blank of the valve block shall be forged before processing.

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.

The dimensions of hydraulic components installed on the hydraulic valve block shall not interfere with each other. The geometric dimension of the valve block mainly considers the external dimension of the components installed on the valve block, so that there is enough assembly space between the components.
