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 0.8μm, 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.

 

3. In terms of detection, AAK uses the German Diatest small pore diameter measuring instrument to check each valve hole of the hydraulic pressure control valve, and the measurement accuracy range can reach 0.1μm at least, ensure the concentricity of the valve hole is consistent, and most hydraulic valve manufacturers use random sampling inspection.

 

Davis privately told that the boss was very happy with AAK's help regardless of past grievances, and was also satisfied with Davis's ability to deal with unexpected problems.

 

AAK hydraulic pressure control valve has a performance of 2 million times of long service life. You can also have a small test!
