AAK hydraulic pressure control valve has a performance of 2 million times, Davis will not change the supplier any more
Davis comes from a hydraulic equipment company in the United States. He has cooperated with AAK for 4 years, and it is very smooth. It is strange that since an inquiry of hydraulic pressure control valves in the second half of last year, there has been no new inquiry from him, only the reorders of some hydraulic cartridge valves. At the beginning of August, Davis asked about the production time of 200 hydraulic pressure control valves, and only then did we know that why he did not place orders for new valves for a long time. In the second half of last year, he found a hydraulic valve manufacturer whose price was more than 20% cheaper than that of AAK, so he moved the business to that manufacturer. But now troubles come out one after another, the boss is very dissatisfied, and he is under great pressure.
The most troublesome thing is that a three grip electro-hydraulic puller is weak in grasping due to the leakage of the hydraulic pressure control valve. However, the manufacturer of the original hydraulic pressure control valves prevaricated, and the high frequency of use of the equipment caused the wear of the valve body, and even refused to replace the goods. Davis regretted his decision. He caused big trouble for the first time because of the 20% price difference, and had to get back to AAK. In the past 4 years of cooperation with AAK, there was no complaint. In order to help Davis get out of the predicament as soon as possible, we adjusted the production arrangement of the workshop. 2 weeks later, 200 hydraulic pressure control valves were delivered. Davis also sent me the drawings of other valves produced by that manufacturer with lower price, and asked me to be prepared for production.
AAK hydraulic pressure control valve is wear-resistant and leak free, ahead of most hydraulic valve manufacturers in 3 aspects, which are also the important points to ensure the performance of 2 million times.
1. In terms of materials, AAK adopts German 20CrNi2MoV high carburized bearing steel. Through secondary quenching + cryogenic treatment + low temperature tempering process, its microhardness is 237 ~ 247HV, and its wear resistance is 3 times higher than that of similar steels. Most hydraulic valve manufacturers may know how to choose materials, but they may not do a good heat treatment.
2. On the equipment, AAK uses the Japanese NP520X-F full-automatic grinder to finish the valve spool. The surface of the processed valve spool is like a mirror with an accuracy of 0.8�¼m, the flexibility of the valve spool is improved by at least 2 times. Most hydraulic pressure control valve manufacturers can not process the same quality valve spool as AAK.

Hydraulic Cartridge Pressure Control Valve with 450bar pressure resistance, AAK's service life is twice that of its peers Gallagher is from a hydraulic equipment manufacturing company in Brazil. His purchase has been smooth, but a hydraulic cartridge pressure control valve stumped him. In the second half of last year, they purchased high-pressure hydraulic cartridge pressure control valves for hydraulic power units. About half a year later, a customer complained that the hydraulic cartridge pressure control valve was leaking. According to the feedback from the original hydraulic cartridge pressure control valve manufacturer, the leakage was caused by ultra-high pressure 450bar and it can only be replaced with new one. Gallagher realized that the service life of the hydraulic cartridge pressure control valve produced by the original manufacturer was only 6 months, and the customer required at least 1 year. Gallagher contacted other cartridge valve manufacturers, but none of them was able to guarantee the service life of 1 year for the hydraulic cartridge pressure control valve that is resistant to ultra-high pressure of 450bar. Gallagher was worried. Gallagher found AAK website on B2B, noticed many customer cases related to hydraulic cartridge pressure control valves, and sent an email asking: Can AAK ensure that the hydraulic cartridge pressure control valve withstand ultra-high pressure 450bar working condition, and the service life is more than 1 year? According to the hydraulic system schematic diagram and the original production drawing of the hydraulic cartridge pressure control valve, AAK engineers found that the pressure relief method has a great impact on the valve, will consume the valve life, and is easy to leak. Gallagher asked AAK to make samples. After 35 days, AAK delivered 30 hydraulic cartridge pressure control valves. Last week, Gallagher informed us by email that AAK hydraulic cartridge pressure control valves had been used for 9 months, and no customer complained about leakage. The boss asked to purchase in bulk from AAK to replace the original hydraulic cartridge pressure control valves. I told him that 1 year's life is our basic requirement. He told me that his boss valued the service life of AAK hydraulic cartridge pressure control valve. The other cartridge valve manufacturers can only guarantee a service life about 6 months, while AAK could last more than 1 year. The pressure relief mode of this hydraulic cartridge pressure control valve, is optimized from the following 3 points: 1. The valve body of the hydraulic cartridge pressure control valve is divided into the upper valve body and the lower valve body, and then sealed and fastened with bolts to form the valve body. One end of the valve hole of the upper valve body is used as the pressure fluid inlet, and one end of the valve hole of the lower valve body is used as the pressure fluid outlet.
