AAK Hydraulic Cartridge Needle Valve of High Stability

Amistad is from a hydraulic equipment company in Spain. His purchase has been
smooth in the past 3 years. Some time ago, their company developed an automatic
hydraulic ladder truck, and the hydraulic cartridge needle valve used was from
a local supplier who had cooperated with their company for 3 years. During the
commissioning of the hydraulic ladder truck, a hidden danger was found: the
ladder truck fell slightly after the operating lever was suspended. After
troubleshooting, the root cause was locked in the hydraulic cartridge needle
valve. After testing the hydraulic cartridge needle valve individually, there
was no leakage and no abnormal function. The manufacturer of the hydraulic
cartridge needle valve recommended that another hydraulic cartridge check valve
be integrated to assist the hydraulic cartridge needle valve. However, this
would change the original design of the manifold and increase the cost, and
this solution was rejected by the boss. Amistad contacted more than 10
hydraulic cartridge needle valve manufacturers, but after a week, it didn't
work out. Amistad was worried.

Amistad found AAK while browsing Google and left a message: How to optimize the
hydraulic cartridge needle valve for hydraulic equipment with abnormal lifting?
I guessed that he was in trouble when purchasing hydraulic cartridge needle
valves. After communication, I learned the above story. According to his
hydraulic schematic diagram, production drawings of hydraulic cartridge needle
valve, and equipment working video, I told him first that it was not advisable
to add components to the hydraulic manifold, which showed that the ability to
control the hydraulic cartridge needle valve was not enough. Among the 5 steps
of Musk's work method by Tesla's boss, 2 of them mentioned to simplify or
optimize the traditional processes or components.

Amistad seemed very interested in my idea. He was willing to try it once and
asked us to sample it. After 45 days, AAK sent 6 samples of the hydraulic
cartridge needle valve. 3 weeks later, he told me that after AAK hydraulic
cartridge needle valve was installed on the ladder truck, it really eliminated
the risk of "slight falling". He asked me to provide the price of this
hydraulic cartridge needle valve. Strangely, 6 months after the price was sent,
there was no any news from Amistad. Last week, Amistad suddenly "showed up",
and sent a PO for 360 hydraulic cartridge needle valves, without discussing the
price. He specifically mentioned that the high stability of their ladder truck
conquered their users, and the equipment reservation exceeded expectations.

How does AAK optimize the hydraulic cartridge needle valve? In view of this
hidden danger, we adopt the proportional screw type instead of the traditional
sliding type, whose valve seat sealing performance is improved by at least 30%,
and has good compression resistance. AAK hydraulic cartridge needle valve has 3
major functions (multistage flow, stable load and rapid check) and 2 major
performances (stability and reliability). It only needs a joystick to achieve
precise positioning, and the flow of the hydraulic cartridge needle valve is
zero, so there will be no leakage. The ladder truck can be instantly fixed at
the designated position without falling. Most of the hydraulic systems of
ladder trucks not only have hydraulic cartridge needle valves, but also have
hydraulic cartridge check valves, which is not only costly, but also has
potential stability problems. I think that maybe this is the reason why the
ladder trucks of Amistad’s Company are so popular.

AAK hydraulic cartridge needle valve is stable and reliable. You can also have
a small try!
