Product Description

After the previous article talking about the manufacturing process of hydraulic valve block, we received many customers' message on our website. The new customers have not purchased our AAK hydraulic valve block yet, so it is understandable to have worries. In order to further clarify the quality advantages of AAK hydraulic valve block, I will talk about some production precautions of AAK in the production process of hydraulic valve block, as follows:
 
1. 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.
 
2. In the design of hydraulic valve block, the oil circuit should be as simple as possible, and the deep hole, inclined hole and process hole should be reduced as far as possible. 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.
 
3. All screw holes on the valve block should have machining accuracy requirements. Generally, 7h is selected. The machining accuracy of the mounting holes of threaded cartridge valves meets the requirements of product samples. The roughness of the mounting holes of cartridge valves is Ra0.8. In addition, there are also dimensional tolerance and geometric tolerance requirements. The surface roughness of 0-ring groove is Ra3.2, and the surface roughness of general runner is Ra12.5.
 
4. The high pressure valve block should be made of 35 forged steel, and the general valve block should be made of A3 steel or ductile iron. When cutting the valve block material from the plate by gas cutting, enough machining allowance should be reserved, and it is better to forge the blank of the valve block before machining. The material for processing valve block shall be compact in internal structure, free from interlayer, trachoma and other defects, and the blank shall be detected if necessary. Cast iron blocks and larger steel blocks should be aged and pretreated before processing.
 
The important component of the hydraulic valve is the hydraulic valve block, which plays an important role in controlling the direction, pressure and flow of the liquid flow in the hydraulic valve. AAK has its own proprietary technology, quality control system, never careless. If you also need to purchase hydraulic valve block, please contact us.
