The hydraulic relief valves produced by AAK has pressure for 100%, the stability is over 90% of the peers, which helped a Spanish importer became more and more important for his VIP customer.
At present, in the domestic market, more than 90% of the hydraulic valve manufacturers' hydraulic valves will have the case of no pressure, because of the assembly process is not cleaned enough, leading to the existence of foreign bodies between the valve spool and the valve seat. However, one of the most important reasons is that the accuracy of the hydraulic valve is not enough, so that the valve spool is stuck in the process of use, the pressure is abnormal, and the manufacturer has to catch up with the schedule and save the cost. Under these conditions, there are many problems, and of course, customer complaints are increasing.
A Spanish importer of hydraulic valves purchased a batch of hydraulic relief valves in China some time ago. Nearly 20% of the hydraulic relief valves had unstable pressure, and there was no pressure in the hydraulic system during use, which resulted in that they could not be supplied to his customers in time. The VIP customer of the company complained to his boss because he couldn't receive enough goods.
After knowing this, the boss demanded to meet the quantity required by this VIP customer within 3 weeks. However, the original hydraulic manufacturer's technology suck up and always failed to get the exact solution. When he hesitated, he happened to see the link of our AAK website on Google. After further checking, he took the initiative to contact us. After a brief introduction and discussion, he hoped that our technical team would have a meeting with him now. After more than 2 hours of communication, he sent us a design drawing and inventory sample picture of his hydraulic relief valve, and asked us to submit our approval sample within 10 days. Soon, we sent our hydraulic relief valve sample within 5 days, and also received the sample fee and express fee he paid voluntarily.
A month later, I received this order contract for his hydraulic relief valves in the early morning, which I thought it was not going to carry out. Later I learned that he had asked many hydraulic valve manufacturers to send samples. Finally, through parameter comparison, the stability of our AAK hydraulic relief valve and our proofing efficiency were recognized by their VIP customer. So they decided to place an order with AAK without hesitation.
In order to make sure that the produced hydraulic relief valves have pressure for 100% in the hydraulic system, during the assembly process, AAK hydraulic relief valve is cleaned 3 times with oil to clean the foreign matters between the valve spool and the valve seat, and then each hydraulic relief valve is tested with a precision inductance measuring instrument to ensure the stability of each AAK hydraulic relief valve and avoid the valve spool sticking. AAK has meticulous production attitude, not only to keep pace with the times on the technology, but also the stability of AAK hydraulic relief valve can catch up with and surpass 90% of its peers.
