AAK hydraulic valve block uses aviation aluminum, William admired

William comes from a Canadian hydraulic equipment company and has purchased
hydraulic valve blocks in Ningbo for several years. AAK also supplies several
difficult hydraulic valve blocks to their company. Although the quantity is not
big, AAK service makes William very satisfied. In the second half of last year,
William emailed an inquiry for a big quantity of order for hydraulic valve
blocks. William said that the quotation was 40% higher than that of other
hydraulic valve block manufacturers. I'm not surprised at all that he advised
that the price of AAK hydraulic valve block is 40% higher.

According to the hydraulic valve block drawing provided by William, AAK
engineers found that according to the working condition requirements of the
hydraulic valve block and the minimum wall thickness between two adjacent
parallel holes (including installation threaded holes) in the middle of the
valve block designed on the hydraulic valve block drawing is less than 4mm, the
6061-T6 Aluminum material marked in the drawing is not suitable, because this
wall thickness can not bear the pressure of 350bar at all. During the operation
of the equipment, the hydraulic valve block is likely to be broken down because
it cannot withstand high pressure, that is, the materials used for the
hydraulic valve block must be changed, rather than blindly follow the original
hydraulic valve block drawing. AAK uses 7075-T6 aviation aluminum, which is the
root cause of 40% higher price. A week later, William replied that he also sent
the inquiry to the old hydraulic valve block supplier and more than 10 other
hydraulic valve block manufacturers, but none of them suggested change the
aluminum materials. He wondered whether AAK deliberately changed the materials
for more profits. This large order of hydraulic valve blocks had been placed
with the original supplier. Then I replied with a few words: good luck.

Two months later, William sent an email saying that he regretted that he had
not followed AAK suggestion at the beginning. The hydraulic valve block sample
from old supplier was debugged 3 days after the equipment was installed. The
manufacturer of the hydraulic valve blocks said that the sample was completely
in accordance with the drawing and the development cost could not be refunded.
The equipment commissioning time was wasted. The boss was very unhappy and
asked William to try AAK samples even if the price was 40% higher, and asked to
send the hydraulic valve block samples as soon as possible. AAK uses 7075-T6
aviation aluminum to make samples by soonest. After 30 days, AAK sent 2 samples
of hydraulic valve blocks.

Last Monday, when I opened the mailbox, I saw the unread email of hydraulic
valve blocks from William. I knew that AAK hydraulic valve blocks passed the
test of equipment commissioning. After opening, as expected, he placed a large
order of 800 hydraulic valve blocks at one time. He also felt sorry to mistake
AAK professional suggestion for deception.

The 6061-T6 material on his hydraulic valve block drawing is only suitable for
hydraulic valve blocks with a pressure below 220bar and a wall thickness of
more than 5mm. Compared with 6061-T6, 7075-T6 aviation aluminum material has
high strength, high hardness, more precision, good toughness, can be pressed or
impacted for a long time, is not easy to deform, and has excellent wear
resistance and fatigue resistance. It is the aluminum alloy with the highest
strength at present.

AAK hydraulic valve block is highly professional and cost-effective. You can
also have a small try!
