AAK Hydraulic Pressure Valve Has No Horn Hole, saving Adair’s order

AAK hydraulic pressure valve has no horn hole. In Ningbo, the hydraulic valve
production base, few factories are sure to solve the horn hole. AAK uses
automatic programming software to program and upgrade the processing technology
of hydraulic valve cavity hole. The geometric tolerance of each hole is within
0.02mm. At the same time, small fillet is used to replace the R angle of our
peers to transition, which completely avoids the horn hole.

Most hydraulic valve manufacturers use manual programming to design the
geometric tolerance of cavity hole, which is prone to human error and can not
be corrected. At the same time, due to the limitation of operation methods, the
transition angle between small holes in the hydraulic pressure valve generally
adopts the R angle for transition, which is easy to artificially leave a small
space that is not easy to detect, so the horn hole will probably appear. After
the hydraulic pressure valve is used for a period of time, the horn hole is
easy to leak. What's more troublesome is that the oil stain outside the
hydraulic pressure valve is easy to enter the valve spool and damage the whole
hydraulic system.

Adair, a hydraulic valve purchaser in Scotland, had many contacts with AAK
hydraulic valve before, because he pursues low price, there is no cooperation
between us. In July this year, he placed an order for hydraulic pressure valve
worth 80,000 US dollars to a hydraulic valve manufacturer in Ningbo. 2 months
later, the quality of the hydraulic pressure valve failed to meet the standard
every time. Adair realized that even if it took another 2 months, the sample
still could not be approved. Adair accidentally saw an article from AAK about
"horn hole" on the B2B website, he further sourced until he got to the AAK
website:, he realized that it was the hydraulic valve
manufacturer he had been contacting.

When we received Adair's email, we understood the problems and causes of his
hydraulic pressure valve. 3 days later, we received the hydraulic pressure
valve samples that he asked the original hydraulic valve manufacturer to send,
we found that the processing coaxiality of the cavity hole diameter of the
combined holes of these hydraulic pressure valves was between 0.03-0.05mm, and
there were tool connecting traces at the transition R angle. After we took the
video and sent it to him, he understood why the samples of the original
hydraulic valve manufacturer were always not approved.

After receiving the video, Adair transferred the order of this hydraulic
pressure valve to us AAK hydraulic valve the next day. At the same time, Adair
also joked that you found the problem, but not means that you are able to solve
the problem. How does you AAK hydraulic valve do and make me believe that you
can 100% solve these hidden problems.

AAK hydraulic valve is good at finding the pain points of traditional process,
and is more willing to take time to improve or innovate the production process
of hydraulic valve. Many times, the process has been one step ahead of the
peers. For example, this hydraulic pressure valve is programmed by automatic
programming software, which replaces the manual programming commonly used by
our peers. After the hydraulic pressure valve automatically generates the
cavity hole, then next step is processed. The geometric tolerance of each hole
must be controlled within 0.02mm. If it does not meet the standard, the next
step of processing will not be carried out. At the same time, each transition
angle between the small holes of the hydraulic pressure valve uses a small
fillet to replace the common R angle of our peers. By optimizing the processing
parameters of the cartridge hole, the horn hole is completely avoided.

AAK hydraulic pressure valve has no horn hole, feeling at ease to use. You can
also try a small order.
