For the Hydraulic Pressure Control Valve with 1.0μm precision, Santos only recognizes AAK

Santos is from Poland, and has been purchasing hydraulic cartridge valves from China for 2 years. Recently, they developed a hydraulic power unit that required 1.0μm accuracy hydraulic pressure control valve. He made samples from a hydraulic pressure control valve manufacturer that has been cooperating for 2 years. During equipment debugging, it was found that the hydraulic system's pressure supply was unstable, and the root cause was that the accuracy of the hydraulic pressure control valve spool and hole did not meet the standard, most of which were in 2μm. The original manufacturer of the hydraulic pressure control valve stated that he cannot afford this precision and has to surrender. Santos contacted other hydraulic pressure control valve manufacturers, but there was no result. His boss was not satisfied with the procurement efficiency, so Santos was in a worry.

Santos browsed the AAK website on B2B.
