AAK Hydraulic Pressure Control Valve 2μm Precision Accuracy

Jeff comes from Israel and has been purchasing hydraulic pressure control valves from China for less than 2 years. At the beginning of this year, a hydraulic pressure control valve with valve seat precision accuracy within 2μm has worried him for over 1 month. This hydraulic pressure control valve is used for hydraulic power units in the aviation industry. The hydraulic pressure control valve sample provided by the original manufacturer showed slight leakage after pressurization. Jeff's engineer found that the valve seat precision accuracy of the manufacturer was around 4μm. Jeff had to search for a new manufacturer of hydraulic pressure control valves. 

Jeff left a message on the AAK website: Can AAK control the valve seat precision accuracy of hydraulic pressure control valve within 2μm? After communication, it was learned that he encountered difficulties in purchasing hydraulic pressure control valves from China.
