AAK hydraulic valve block, pressure resistance over 450bar, no oil leakage

Connor is a purchaser from a Russian hydraulic company. There has never been
oil leakage due to sealing in his previous purchases of hydraulic valve blocks.
Some time ago, a rated pressure up to 450bar hydraulic valve block let him
suffer due to the oil leakage of the hydraulic valve block. He communicated
with the original manufacturer for many times and debugged for 3 times, but the
oil leakage problem still cannot be solved. He then asked his other hydraulic
valve block suppliers, they all suggested Connor giving up, because the current
sealing technology cannot meet the pressure rating of 450bar hydraulic valve
block.

Connor also communicated with some new hydraulic valve block manufacturers
online, and gradually understood the shortage of sealing technology. The 90% of
hydraulic valve block manufacturers use the conventional sealing method of
hexagon socket plug and sealing combination gasket, which is suitable for
hydraulic valve blocks with rated pressure of 50-350bar only. For any over
350bar, this sealing method does not work and they have to give up.

Can the sealing problem on a hydraulic valve block with 450bar rated pressure
really not be solved? Connor still didn't give up. He found AAK hydraulic valve
on B2B and came across an article about AAK hydraulic valve block using Swiss
sealing technology to solve the oil leakage of hydraulic valve block. He left a
message on our website: can you really solve the problem of oil leakage of
hydraulic valve block with rated pressure above 450bar? Seeing this message, I
realized that he should have been cheated by other manufacturers before, so he
doesn't believe in the new hydraulic valve block manufacturers easily. We
replied to him, no matter how much we said, maybe you don't believe it. Simply
put, you directly order 1pc of hydraulic valve block according to your drawing.
If the hydraulic valve block produced by AAK still leaks oil, we will directly
refund you the fee of this testing order.

Maybe Connor has no other choice or he sees hope, he agreed our suggestion. 14
days later, he received AAK hydraulic valve block. 2 days later, the test
result came out. Their engineers deliberately pressurized it to 550bar, and no
hidden danger of oil leakage was found in AAK hydraulic valve block. He
wondered why AAK hydraulic valve block had no problem with even a rated
pressure at 550bar?

The reason that AAK hydraulic valve block can operate normally in the hydraulic
system with the pressure of 550bar is because of the introduction of new
sealing technology and MB Series Plug of KVT company in Switzerland. This plug
mainly forms a solid sealing surface after intermetallic extrusion in the way
of expansion and bite, so as to 100% avoid oil leakage of hydraulic valve
block, fundamentally solve the problem of high-pressure sealing of hydraulic
valve block. At the same time, it reduces pollution, so that the hydraulic
valve block is more stable. This is also why Connor recognized the quality of
AAK hydraulic valve block.

AAK hydraulic valve block, superior sealing, zero leakage, you can also have a
small try.
