| Message: | Demetrius comes from a hydraulic equipment manufacturing company in Greece and has been purchasing hydraulic cartridge valves from China for 2 years. In the second half of last year, a hydraulic cartridge valve with high requirements for all parameters made him very upset. Their company's newly developed hydraulic unit did not go smoothly in the testing, and the hydraulic cartridge valve purchased by Demetrius had a pressure holding time of only 1-4 weeks. The root cause was either this parameter did not meet the standard or that parameter did not meet the standard. The original hydraulic cartridge valve manufacturer tested 3 times but still did not meet the standard. Time has been wasted for more than half a year, and the engineer complained to the boss. Demetrius was very anxious.
Demetrius found AAK and contacted us. After communication, we learned that he had encountered difficulties in purchasing hydraulic cartridge valves. Based on the parameter requirements provided by Demetrius for hydraulic cartridge valves, AAK engineers analyzed and found that this hydraulic cartridge valve has high requirements; Close attention needs to be paid during the durability testing. I told him that not only the production of this hydraulic cartridge valve is very important, but also the testing on the various parameters of the hydraulic cartridge valve is also very important. Most hydraulic cartridge valve manufacturers do not pay attention to the testing process, resulting in unstable performance of hydraulic cartridge valves. After 50 days, 30 hydraulic cartridge valve samples from AAK were sent out.
