AAK Hydraulic Directional Control Valve Twice Service Life of Peers

Erasmus is from a hydraulic equipment company in Colombia. He has been
purchasing smoothly, but a batch of hydraulic cartridge directional control
valves stumped him. The loader sold by their company less than 1 year has been
complained of shaking. During after-sales service, it is found on the site that
the valve spool of the hydraulic cartridge directional control valve is stuck
during operation, which is caused by the deviation of the valve hole accuracy.
The original manufacturer advised that there should be not many pieces of
hydraulic cartridge directional control valve was stuck and could be replaced,
but there were more and more complaints later. The boss was not satisfied with
Erasmus's purchase this time, asked him to replace the manufacturer of the
hydraulic directional control cartridge valve, and requested that the service
life of the valve be more than 18 months. Erasmus contacted more than 10
cartridge valve manufacturers. They either disliked the small quantity or
needed 60 days of production. Erasmus became very anxious.

Erasmus found AAK hydraulic valve in B2B and left a message to us: Can you
produce the hydraulic cartridge directional control valve in 40 days with a
service life of 18 months? I guess he encountered problem when he purchased the
hydraulic cartridge directional control valves. After communication, I learned
his dilemma in purchasing. According to the drawing of hydraulic cartridge
directional control valve provided by Erasmus, this is not difficult, but the
key is performance. 2 days later, we received the PO for the hydraulic
cartridge directional control valve. Erasmus said that although the price of
AAK hydraulic cartridge directional control valve was 20% higher than that of
the original cartridge valve manufacturer, he still chose AAK because he valued
the 18 months of service life. After 40 days, AAK sent 40 samples of hydraulic
cartridge directional control valves.

Last week, Erasmus informed by email that the AAK hydraulic cartridge
directional control valve had been installed on the equipment for 1 year, and
there was no customer complaint. Most surprising to his engineers, AAK valve
hole accuracy reached 0.3μm, but the original directional control valve
manufacturer is above 0.7μm. I told him, if no accident, there will be no
worries for 18 months. AAK constantly improves the performance of the hydraulic
directional control cartridge valve from 3 aspects. Although the price is 20%
higher than that of peers, the service life is twice that of peers.

1. In processing, this hydraulic cartridge directional control valve uses OKK
ultra precision machine tool of Japan, and its nano level numerical control
system ensures that the processing accuracy can reach 0.01~0.3 μm. The
precision of shape and contour is 0.003 ～ 0.1μm.

2. In terms of detection, the German small micropore diameter tester is used to
detect the valve hole of each hydraulic directional control cartridge valve.
100% full inspection, and the measurement accuracy is within 0.1μm.

3. In terms of assembly, most of hydraulic directional control valve
manufacturers adopt the selective assembly method. AAK uses the unified
assembly method, and the assembly efficiency is twice that of peers. Not only
fast, but also stable.

Although the price of AAK hydraulic directional control cartridge valve is 20%
higher than that of its peers, its service life is twice that of its peers. You
can also try a small order!
