For Hydraulic Cartridge Pressure Control Valve with 2μm Accuracy Spool, AAK is unique from processing to detection

China [CN]

Chadwick is from Israel and has just purchased hydraulic cartridge valves from manufacturers in China for no more than half a year, but encountered problems when purchasing a hydraulic cartridge pressure control valves. One of their hydraulic manifolds needs a hydraulic cartridge pressure control valve with 2μm accuracy spool. Chadwick knew that the accuracy was high, so he chose a hydraulic cartridge valve manufacturer in Ningbo from the current supplier list. Perhaps the working conditions have high requirements. The original manufacturer has tested 3 times, and each time several hydraulic cartridge pressure control valves leaked. The original manufacturer can only give up because the valve spool accuracy of this hydraulic cartridge pressure control valve is not easy to control. Time has been wasted for almost 3 months, Chadwick was very anxious.

I'm not sure how Chadwick found AAK. The message he left us was only a picture of the valve spool, with a question if AAK is able to meet 2μm accuracy? For questions like this, whether the answer is yes or no, it is not persuasive. I only told him that AAK provided hydraulic cartridge valves with 1μm accuracy spool for Russian customers previously, and did not say too much. The next day, Chadwick sent detailed drawings of the hydraulic cartridge pressure control valve. After communication, it was learned that he had wasted 3 months with the original manufacturer. I told him that AAK only make samples one time, either get it done or give it up because this valve spool is really a bit special. After 40 days, AAK sent out 30 hydraulic cartridge pressure control valves.

1 month later, Chadwick sent us an order for 200 pcs of hydraulic cartridge pressure valves, which means that AAK hydraulic cartridge pressure control valve has been recognized. I told him that the main focus is not only on the precision machining of the valve spool, but subsequent testing is also crucial. Perhaps most hydraulic pressure control cartridge valve manufacturers in China only focus on precision machining but ignore the details of testing. 

AAK hydraulic pressure cartridge valve spool has no abnormalities, because it is only after each valve spool has been tested, the next process can be proceeded. The detection of this hydraulic cartridge pressure control valve spool adopts a Japanese KEYENCE optical axis measuring instrument, which is fully automatic and 360 degree detection. The dimensions, contour, accuracy, and surface roughness of the valve spool do not require manual inspection. Each process is displayed on the computer screen synchronously. If there is a deviation, a red reminder will automatically appear on the screen. The detection of AAK not only avoids human error, but also improves the detection speed by more than 10 times, not only fast, but also very accurate.

AAK hydraulic cartridge pressure control valve, from processing to testing, is unique, you can give it a try!
