Lucas is from a Canadian hydraulic equipment company. He found AAK hydraulic valves online last September. His first inquiry was the hydraulic pilot-operated pressure control valve. After 3 rounds of email communication, he placed a trial order for 20 pcs of hydraulic pilot-operated pressure control valves. I received the order so smoothly, but I didn't expect that AAK would almost take the blame for others in the first cooperation.

 

At the beginning of last month, Lucas informed by email that there were problems with all 20 hydraulic pilot-operated pressure control valves provided by AAK. When the equipment was installed and debugged, the hydraulic system went on strike. This is the first time I have encountered such a complaint. AAK will do various tests on each hydraulic pilot-operated pressure control valve before leaving the factory, and deliver it only after it is qualified. I asked the engineer and the workshop to verify. It was proved that the programming and production of the hydraulic pilot-operated pressure control valves are completely consistent with the drawings provided by Lucas, so I can ensure that the samples of AAK hydraulic pilot-operated pressure control valves are qualified.

 

Our engineers speculate that there may be a problem with the oil circuit design of the valve block system, but Lucas engineers believe that AAK is shirking the responsibility. So I suggest Lucas try the hydraulic pilot-operated pressure control valves of other manufacturers to debug. If the hydraulic system is still abnormal, our guess is right. Two weeks later, Lucas frankly told us that there should be a problem with the oil circuit design and asked us what good methods we had?

 

The next day, Lucas sent us the video of equipment commissioning. Indeed, during the operation of the equipment, the speed increases when the cylinder of the hydraulic system is lowered, which is equivalent to the increase of flow, and the original set pressure of the hydraulic pilot-operated pressure control valve will also increase, resulting in the instability of system pressure. Therefore, it is inferred that the instability of pressure is caused by the thin oil passage of the hydraulic valve block in the system. We suggest that he send us the schematic diagram of the hydraulic system. After analysis, AAK engineers believe that the oil circuit design cannot match the working conditions of the equipment.

 

AAK plans to design and process a new hydraulic valve block, and then installs the AAK hydraulic pilot-operated pressure control valves to debug the equipment. If it is not successful, AAK will not charge any fee for the hydraulic valve block. A month later, AAK sent out the newly designed hydraulic valve block. Lucas sent an email 3 days after receiving AAK hydraulic valve block. He informed that after installing the AAK designed hydraulic valve block and the hydraulic pilot-operated pressure control valves, the hydraulic system was normal and the equipment operated smoothly. Their engineers also admire AAK professional analysis ability and problem-oriented ability to design and production.

 

The failure of a hydraulic valve is not a point problem, but a system. Everything should start from the principle. The average working experience of AAK engineer team is 11 years. Among the hydraulic valve peers in Ningbo, it may not be possible to find the third hydraulic valve manufacturer as such.

 

Lucas privately told us that his boss suggested that in the future, not only the hydraulic pilot-operated pressure control valves should be purchased from AAK, but also the hydraulic manifolds, because AAK specialty conquered his boss.

 

AAK hydraulic pilot-operated pressure control valves, professional analysis, efficient design, maybe there is no 3rd manufacturer like us in Ningbo, you can also have a small try!
