AAK Hydraulic Pressure Control Cartridge Valve 3 Advantages

Leila is from Russia. It has been 2 years since she purchased cartridge valves
from China. She has encountered difficulties in the accuracy and stability of
hydraulic pressure control cartridge valves. In February of last year, their
hydraulic pile driver was complained by customers about its inability after 6
months of use. After checking, it was found that the hydraulic pressure control
cartridge valve had leakage. The original manufacturer of the hydraulic
pressure control cartridge valve advised that that this valve spool accuracy
requirement was high, some hole accuracy of the valve spool may be not up to
standard and caused the leakage. It could only be re-produced, which took 60
days. The after-service sales had to deliver other pile drivers to the customer
for use instead temporarily. The boss was not satisfied with the original
hydraulic pressure control cartridge valve manufacturer, and required Leila to
re-purchase the hydraulic pressure control cartridge valve, which must be
completed within 40 days. Leila was under pressure.

Leila left a message on AAK website:
1. For the hydraulic pressure control cartridge valve, with accuracy of each
valve spool is below 0.8μm and consistent, is AAK able to customize it?

2. Can AAK finish 20 customized hydraulic pressure control cartridge valves
within 40 days?

3. The service life of the customized hydraulic pressure control cartridge
valve shall be 18 months.

This is about the accuracy, production time and service life of the hydraulic
pressure control cartridge valve. After communication, I learned that she had
trouble with the stability of the accuracy of the valve spool, and saw the
information of AAK hydraulic cartridge valve on B2B. I told her that AAK had
encountered these 3 problems before, and there were also practical solutions
for customers. Leila asked me to make samples according to her drawings. After
38 days, AAK sent 20 samples of the hydraulic pressure control cartridge
valves.

Yesterday, Leila emailed us that the pile driver equipped with AAK hydraulic
pressure control cartridge valve has been running for almost 1 year without
leakage or complaint. AAK hydraulic pressure control cartridge valve has been
approved by her boss. They are counting how many hydraulic pressure control
cartridge valves need to be purchased to replace those with hidden dangers.
With the recognition of her boss again, Leila was relaxed and pressureless. AAK
hydraulic pressure control cartridge valve has fulfilled 3 major requirements
of Leila, by making efforts in material selection of valve spool, component
processing, equipment selection and quality control.

1. The valve spool material 20CrNi2MoV, imported from Germany, is adopted by
AAK, combined with AAK's personalized carburizing pretreatment process, through
secondary quenching + cryogenic treatment + low-temperature tempering process,
the microhardness of the valve spool is 237~247 HV, and the service life of the
valve spool has been increased by at least 3 times.

2. The processing equipment adopts Japanese OKK ultra-precision machine tool,
and the old technicians operate the tool to ensure the accuracy of valve spool
can reach 0.3-0.5μm. And the production efficiency is more than 30% faster
than other machine tools.

3. In terms of the testing instrument, the German Diatest micro-pore diameter
measuring instrument is used, which can inspect each valve hole accurately.

AAK hydraulic pressure control cartridge valve, has consistent accuracy and
service life of more than 18 months. You can also try it!
