AAK Hydraulic Manifold Block, Economical, Efficient, Reliable

Achilleas comes from a Greek hydraulic equipment company. One of their rollers
was complained by users because of oil leakage. After sales personnel found
that there was a large gap in the valve block used for hydraulic manifold,
which was the root cause of oil leakage. After further disassembling the
hydraulic manifold, it was found that there were cracks in the lower left and
right corners of the valve block. They thought that the problem can be solved
by replacing the valve block. However, after 2 months of construction, the old
problem was happened again. The engineer asked Achilleas to consult the
original hydraulic manifold manufacturer. The manufacturer was not sure why the
valve block broke within 2 months. Achilleas was helpless.
Achilleas realized that he could only contact AAK for help, because he also
sent the inquiry for this hydraulic manifold to AAK before. At that time, AAK
proposed to modify the oil circuit and hydraulic valve selection, but it was
not accepted by their engineers. I was not surprised to receive his email. At
the inquiry stage last year, our engineers found that there was an energy
conflict between the oil circuit aperture of the hydraulic manifold and the
selected hydraulic valve, resulting in the frequent instantaneous pressure rise
of the hydraulic system. In particular, the oil circuit wall thickness at the
left and right lower corners of the valve block is not enough, so it is not
surprising that the valve block is cracked. This time, Achilleas didn't go to
their engineers to verify.
AAK redesigned the oil circuit, re selected each hydraulic valve, and sent the
hydraulic manifold block sample after 30 days.
Last week, Achilleas sent an email saying that after replacing with AAK sample
for such a long time, there was really no problem. Moreover, the total price
was saved by 20% compared with the original one, and the customer feedback that
the action sensitivity was also improved a lot. This time, even their engineer
also suggested that the boss should give the design and production of the
hydraulic manifold block to AAK in the future. He also wants to know why AAK is
so good?

I told him that the most important thing in the design of the hydraulic
manifold block is to determine the operating parameters of the hydraulic
system, understand the requirements of the system for the maximum working
pressure and maximum flow, and reasonably design the oil circuit. Secondly, the
pressure drop of the valve must be considered to ensure that the pressure drop
through the pressure valve, flow valve and directional valve is not too high,
which will affect the load action and cause the pressure problem of the valve
block.
AAK has more than 20 years of industry experienced professional engineer from
German HAWE company, who have unique experience in the design of hydraulic
manifold blocks, especially in the oil circuit design. Combined with the system
principle, through the reasonable selection of hydraulic valves and the
innovative and optimized design of the oil circuit of the valve block, the oil
leakage caused by high pressure can be avoided, and an efficient, economical
and reliable hydraulic manifold block can be produced. Maybe there is no such
second hydraulic manifold block manufacturer in Ningbo.
AAK hydraulic manifold block is economical, efficient and reliable. You can
also try it!
