AAK impressed German customer with 3 points for hydraulic cartridge check valve with length diameter

4 hydraulic valve manufacturers, made samples for 5 samples, but none of them were able to produce the hydraulic cartridge check valve with a length diameter ratio of 25:1 successfully. AAK adopted a special slender shaft processing technology, and the sample passed the testing successfully at one time, the parameters of the hydraulic cartridge check valve were up to standard, and the surface roughness was improved by 0.3%, and the geometric accuracy was improved by 0.8%.

Cheney is a senior buyer of hydraulic cartridge valves in Germany. But this time, he was trapped by a hydraulic cartridge check valve with the ratio of shaft length to diameter greater than 25. Four hydraulic cartridge valve manufacturers, made samples for 5 times, spent 10 weeks, but without any results.

When he was browsing B2B, he saw AAK and noticed that AAK had an article about the hydraulic valve with long length diameter ratio.
