William is a purchaser of a hydraulic equipment company in the United States. At the beginning of last year, a South American customer wanted to customize a drilling machine for geological exploration. The South American customer promised to order this equipment for a long time if it has excellent performance and stability. The owner asked the engineers to design and test samples. According to the working conditions, the maximum pressure of the hydraulic system is 450bar or above, which has a very high requirement on the pressure resistance and stability of the hydraulic pilot operated pressure control valves.
When William received the task of purchasing this hydraulic pilot operated pressure control valve, he felt a big pressure, because the pressure resistance of normal hydraulic pilot operated pressure control valve is basically 250bar, and the maximum pressure resistance provided by previous hydraulic valve manufacturers was also only 380bar. He asked all the hydraulic valve manufacturers that he contacted before, they basically replied that according to this working condition, their hydraulic pilot operated pressure control valve can only ensure a service life of 3 months, but the customer asked for a service life of 1 year.
William also contacted the local hydraulic valve manufacturers in the United States. They told him that he could not promise a service life of 1 year for this hydraulic pilot operated pressure control valve. They can only test the samples first, then to know the service life. One of his other hydraulic valve manufacturers in China introduced AAK to him. He told William that AAK shipped a hydraulic pilot operated pressure control valve for a working condition of maximum pressure 450bar before, but the service life required by that customer is 6 months.
After receiving the drawings of the hydraulic pilot operated pressure control valve from William, AAK technical team found that the requirements of this hydraulic pilot operated pressure control valve were higher than those of our last shipment. The conventional No. 45 steel could not meet the requirements, so we had to find special steel. Later, after 5 times of material selection and testing, 2 months later, AAK internal sample testing was successful by using a German steel with high wear resistance and high fatigue resistance. After sending the samples of hydraulic pilot operated pressure control valve, we have been waiting for news from William. William said that no news from customer is the best news.
Last month, 1 year after AAK samples were sent, William emailed us that he would order 100 hydraulic pilot operated pressure control valves at one time. The quality standard is the same as that of the hydraulic pilot operated pressure control valves sent last year. Because the other hydraulic valve manufacturers in China can only ensure the service life of 3 months,
