AAK Hydraulic Directional Control Valves For Electric Vehicles

Giuseppe is from a hydraulic equipment company in Italy. As an old purchaser,
he has been enjoying good luck. In the second half of last year, their company
obtained the annual order of hydraulic power units used for the tail plate of
electric vehicles, but the customer requested that the price should be reduced,
and the hydraulic directional control valves used in the power unit should be
reduced by 10%. The manufacturer of the hydraulic directional control valves
who made the samples for them also agreed to reduce the price, but hidden
trouble was brought to the quality at this time.

In the random test of the electric vehicle, the tail plate did not rise
flexibly. After disassembly, it was found that the hydraulic directional
control valve was stuck. The manufacturer of the hydraulic directional control
valves advised that it is an individual phenomenon, but the customer does not
think so. After increasing the detection ratio, some tailboards still can not
be opened. The customer asked for immediate solution, otherwise the annual
order would be cancelled. The boss was very angry and requested Giuseppe to
solve it. Giuseppe contacted more than 20 manufacturers of hydraulic
directional control valves. They either disliked the low price or could not
guarantee that there was no jamming. Giuseppe at this time is under great
pressure.

Giuseppe contacted me. Due to price, our cooperation is sporadic. According to
the hydraulic directional control valve drawings provided by Giuseppe, AAK
found that the original design caused processing difficulties and processing
costs. I replied to Giuseppe that if the original design can be modified, AAK
can accept the price and guarantee 100% no jamming. After 45 days, 100
hydraulic directional control valves were sent. A week later, Giuseppe sent the
shipment schedule for the annual order.

8 months have passed. Last week Giuseppe informed that the customer wanted to
ship the last batch of hydraulic directional control valves in advance. After
using AAK hydraulic directional control valves, the customer no longer
complained about the inflexible lifting of the tail plate.

The hydraulic directional control valve is 100% free of jamming, due to 3
points:

1. The hydraulic directional control valve newly designed by AAK belongs to the
spool valve type. The original vertical poppet type design is replaced by the
"tumbling head" type design. The original function is not changed, and can be
used to compensate for the imbalance of the valve spool in the chamber. At the
same time, it can effectively compensate the original high torque in the
assembly process, so that the valve spool can be controlled freely. Double
protection hydraulic directional control valve, without jamming.

2. AAK adopts Swiss high-precision honing machine to finish the valve spool and
cage, and the accuracy is guaranteed to be within 1μm. Unstable accuracy is
the root cause of the stuck hydraulic directional control valves of the
original hydraulic valve manufacturer.

3.AAK Hydraulic Valve has developed no less than 500 non-standard customized
hydraulic valves for 7 world top 500 enterprises. If without unique skills, it
is difficult to handle.

Giuseppe privately told us that the boss attached more and more importance to
him and wanted him to lead the whole procurement team because he successfully
saved the annual order.

AAK hydraulic directional control valves, flexible and free of jamming, you can
also try it!
