Mastering the key points of hydraulic valve block, AAK improved the design within 30 days and successfully proofed at one time

The hydraulic valve blocks designed and produced by AAK not only has high reliability and small pressure loss to ensure that there is no oil running between the channels, but also has compact structure, small occupied space, simple oil circuit and easy pipe layout, so as to ensure the high efficiency requirements of different actions of various actuator elements. The valve block can control the valve, which is easy to adjust and operate. AAK hydraulic valve block was designed and proofed successfully at one time within 1 month, which impressed the engineers of Samhydraulik company.  

The vast majority of hydraulic valve block manufacturers blindly proofed according to customer drawings, ignored working conditions, and did not understand the internal structure and working principle of hydraulic valve block. It is easy to cause hidden dangers in the hydraulic system, and the problem cannot be found.

Justin left a message on AAK website (www.aakindustry.com) asking is the power insensitivity of the hydraulic system related to the hydraulic valve block? We replied that this is difficult to judge because it is a system problem that needs to be checked one by one. Justin emailed us the next day then we understood why he left such a message.

Justin is from Samhydraulik in Italy. The power unit of a hydraulic system developed by his company needs a hydraulic valve block. Their engineers mentioned that the sensitivity of the power unit is the key and that all components need to cooperate closely. Justin thought that as long as the hydraulic valve block manufacturer strictly controlled the accuracy according to the drawings, it could be easily done. After the hydraulic valve block is finished, it is installed to test the hydraulic power unit. After the oil pump is started, the instantaneous pressure supply at the oil outlet of the power unit does not come up, and it just supply normal pressure after a few minutes. After checking each component one by one, it is suspected that there are hidden dangers in the hydraulic valve block. After detecting the hydraulic valve block, there is no problem in the oil passage and channel of the hydraulic valve block. Justin contacted the original hydraulic valve block manufacturer for analysis and solution. The manufacturer said that the hydraulic valve block was completely produced in accordance with the drawings of Samhydraulik company, and the accuracy was within the required range, and the reason for problem was unknown. Justin contacted several other hydraulic valve block manufacturers, they all said that they could match the drawings, but not sure about the problems of the hydraulic valve blocks.

We asked Justin to tell us the working condition of the whole hydraulic system and the picture of the oil circuit running direction of the hydraulic valve blocks of the original manufacturer. AAK engineers have ideas after 3 aspects of comparative analysis. We told Justin that if your engineer determines that the problem lies in the hydraulic valve block, we will send you two samples of our hydraulic valve blocks to test your hydraulic system. Three days after receiving the samples, Justin informed that the instantaneous pressure supply at the oil outlet of the power unit was normal with AAK hydraulic valve blocks. Their engineers were surprised that AAK completed the design of the hydraulic valve block within 30 days and successfully proofed at one time.

The problem of the hydraulic valve block lies in the high integration of the valve block design and the tortuous oil circuit, which will lead to high pressure loss and slow rise of system pressure. AAK engineers improved the design of the hydraulic valve block. The newly designed hydraulic valve block has no oil running between the channels, compact structure, small occupied space and optimized oil circuit piping, which not only has high reliability but also small pressure loss. AAK chief engineer has more than 20 years of technical experience. He is good at cross-sectional view, measurement and perspective of hydraulic valve block design system, multi angle observation of design process, hole connectivity, oil circuit optimization, and the escort of MDTools 3D solid design and virtual manufacturing software and high-precision CNC machining center imported from Switzerland. Many manufacturers do not know the problem of the hydraulic valve block. AAK can improve the design and make a successful proofing at one time within 30 days. I think this is the difference between AAK hydraulic valve block and its peers.

AAK hydraulic valve block, not blindly based on drawings, but focused on the working principle, you are welcome to have a small try.
