AAK Hydraulic Pressure Control Valve Accuracy within 1.0μm

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 and noticed a customer case of AAK
hydraulic pressure control valves with high precision requirements. He emailed
us to ask: Can AAK ensure that the accuracy of each hydraulic pressure control
valve can be controlled within 1.0μm? After communication, we learned that we
have an existing program for the hydraulic pressure control valve he needs.
Despite Santos' complaints about higher prices than the original hydraulic
valve manufacturer, he still tried ordering 30 hydraulic pressure control
valves.

Last week, Santos informed us via email that after installing the AAK hydraulic
pressure control valve, the hydraulic system's pressure supply was stable.
Their engineers were very satisfied with the accuracy of the AAK hydraulic
pressure control valve, and none of them exceeded 1.0μm. Precision is the most
important test of the quality of a hydraulic cartridge valve manufacturer, it
is not only related to equipment, fixtures, technicians, but also highly
related to the quality level of the manufacturer. AAK hydraulic pressure
control valve, accuracy controlled within 1.0μm, the key lies in 1. precision
machining + 2. detection.

1. In the process of component precision machining, AAK uses SUNNEN honing
machine imported from the United States, with component accuracy controlled
with 1.0μm.

2. In the component detection process, AAK uses the KEYENCE image measuring
instrument imported from Japan, which is not only accurate but also efficient,
and 100% detects the accuracy of each component.

3. In the finished product inspection process, each hydraulic pressure control
valve is tested on a test bench, and its performance is guaranteed.

AAK hydraulic pressure control valve, with precision and worry free
performance, you can also give it a try!
