Hydraulic cartridge valve manufacturer AAK replace European manufacturer

March comes from Brazil, and their power unit is used in a relatively niche
market. The hydraulic cartridge valves used are mostly non-standard. They
used to purchase from hydraulic cartridge valve manufacturers in Europe, and
apart from being expensive and slow in time, everything else was fine.
Recently, he has been trying to purchase from hydraulic cartridge valve
manufacturers in China, and the customization time has been also slow.
However, the quality and functionality of the Chinese hydraulic cartridge
valve manufacturers he has chosen are more troubled than those in Europe,
which makes March very upset.

March left a message on the website of hydraulic cartridge valve
manufacturer AAK:
1. Are you interested and capable of customizing non-standard hydraulic
cartridge valves?
2. According to my drawings, what is the lead time for customized hydraulic
cartridge valves?
3. Is there any guarantee for the stability of the hydraulic cartridge valve
function?

After email communication, we learned that when purchasing non-standard
parts from Chinese hydraulic cartridge valve manufacturers, he encountered
difficulties with the functionality of hydraulic cartridge valves. After
several rounds of communication, March may have confidence in the hydraulic
cartridge valve manufacturer AAK and sent us the drawings, as well as the
samples from the original hydraulic cartridge valve manufacturer. Whether it
is the contour size of hydraulic cartridge valves or the internal structure
of hydraulic cartridge valves, they are very unpopular. Our technical
department is not 100% confident either. In order not to waste March's time,
I suggest that he customize at the same time with previous suppliers such as
European hydraulic cartridge valve manufacturers and AAK. If AAK
customization fails, the development fee will be refunded.

3 months later, after internal testing by AAK, non-standard parts were sent
out. March seems not excited either. The samples from the original Chinese
hydraulic cartridge valve manufacturer also took 3 months, but after 2 weeks
of internal use, the function of the hydraulic cartridge valve became
abnormal. 1 month after the sample was sent out, March sent us an email to
advised that the samples customized by AAK has undergone internal testing
for 1 month, which has basically been recognized by their engineers. Once
their power unit is confirmed by the customer, AAK's hydraulic cartridge
valve will truly pass the standard.

I told March that based on our internal testing curve, I am not worried
about the stability of the hydraulic cartridge valve function unless there
is a change in external working conditions. The customized hydraulic
cartridge valve of AAK uses a self-developed functional testing platform for
functional testing. The customized hydraulic cartridge valve is installed
into the simulated valve block inside the equipment, connected to the
electromagnetic coil, and started to be tested after startup. The valve
spool is automatically opened, and the hydraulic oil begins to work. Where
it goes, the flow and pressure curves of the hydraulic cartridge valve will
be displayed on the display screen of the equipment. After 3 seconds, the
valve spool will automatically close, and the flow and pressure curves at
the time of closure will also be generated synchronously. The obtained curve
is very systematic and visually assesses the function of the hydraulic
cartridge valve. Then, perform the same test again, but increase the working
condition by 20%. Most Chinese hydraulic cartridge valve manufacturers rely
on data and experience to judege the function. There may not be a dynamic
curve in their testing. Even if there is, it may not perform every test
twice.

Yesterday, March sent us an email and their power unit was confirmed by the
customer. They also received the customized samples from Europe, but they
decided to choose AAK hydraulic cartridge valve, which is not only fast and
stable in function, but also more than 30% cheaper than hydraulic cartridge
valve manufacturers in Europe.

For customized hydraulic cartridge valves, AAK may not be inferior to
hydraulic cartridge valve manufacturers in Europe.
