AAK Hydraulic Flow Control Valve Accuracy within 2μm

Maddox comes from Turkey and purchases many hydraulic flow control valves from Ningbo China every year. At the beginning of this year, a hydraulic flow control valve with hole accuracy requirement of within 2μm exhausted him. Their client was developing a hydraulic power unit in the aviation industry that requires the use of hydraulic flow control valves. Maddox still made samples from a hydraulic flow control valve manufacturer in Ningbo, but it didn't go smoothly. It took 75 days for the original manufacturer to adjust the valve hole accuracy twice, but it still couldn't meet the 2μm accuracy standard. The best accuracy can only be at 3μm. The customer has pushed the progress of the hydraulic flow control valve several times. Maddox realized that relying solely on the original manufacturer is difficult to achieve good results.
