AAK New Designed Hydraulic Valve Block Replaces that of the German Factory

At the beginning of last month, Berton sent an email to us, with the theme of
"damn hydraulic valve block", which surprised me. I thought there was something
wrong with the hydraulic valve block purchased by Berton from AAK. After
reading the email, I learned that he purchased the hydraulic valve block from a
German company. There was a leakage problem in the two proofing, and each time
the sampling modifying process was very slow, which affected the commissioning
of the whole equipment. The technical team had complained to the boss, who was
a little annoyed and asked him to get the modified sample of the hydraulic
valve block approved for the third time within 1 month. The German factory
advised that the third hydraulic valve block sample could be solved at one
time, but 1 month was not enough, which made Berton very helpless.

Because this series of hydraulic valve blocks has been purchased in Germany
before, Berton has to wait for the revised sample from the German factory, and
find a new hydraulic valve block supplier at the same time. He wanted to check
if AAK has any good suggestions. I asked him to send the hydraulic valve block
design drawings to us, note the working conditions, and also send the second
unconfirmed hydraulic valve block samples to AAK for comparison.

According to Berton's drawings and the samples of the hydraulic valve block
from the German factory, the finished product quality is good and worthy of
being produced by the German factory. The root cause of the leakage is that the
perpendicularity tolerance between the thread of the hydraulic valve block and
its mating surface reaches 0.08mm, which should not be higher than 0.05mm
according to the working conditions. This tolerance dimension is difficult to
control and has high requirements for the operator, We recommend changing the
system design of the hydraulic valve block. If it is successful, samples of
hydraulic valve blocks can be sent within 25 days. Berton has no better choice
but to wait passively.

5 days after sending the sample, Berton was excited to inform that the sample
of AAK's newly designed hydraulic valve block met the system requirements of
the equipment and did not leak. The accuracy and efficiency of the hydraulic
valve block were both improved compared with the hydraulic valve block of the
German factory. Berton is curious about why AAK dares to change the design of
the German factory. Even the engineers of his technical team admire the new
design of AAK hydraulic valve block.

Based on the design of the German factory, AAK changed the whole oil circuit
design. Some valve holes can be combined with the same unit to perform a
specific type of control function, which is conducive to improving the
execution efficiency of the hydraulic power system. At the same time, the
pressure regulation loop, flow control loop and power supply loop are newly
designed. The reason why AAK dares to make such changes is that we have an
efficient machining center, MIKRON machining center and AMEC sinking drilling
and milling cutter. This combined cutter can directly complete the processing
of the dimensional accuracy required by the diameter of the threaded bottom
hole and the sealing ring, and also the processing of the surface finish.
Moreover, it has central internal cooling and allows faster cutting. In this
way, man-made errors are eliminated in accuracy.

Berton said happily that he could finally ignore the arrogance of the German
factory. The boss asked him to transfer the order directly to AAK, and the
price was cheaper than that of the Germany factory. The boss was very satisfied
with Berton's idea of finding a new supplier of hydraulic valve blocks.

AAK can not only make high-precision hydraulic valve blocks, including
different types of hydraulic valves, but also help you with design solutions.
You can try a small order.
