AAK Hydraulic Pressure Control Valve Benchmarking SUN Hydraulics

Lateef, from Sweden, has been engaged in the procurement of hydraulic valves
for 3 years and has been quite successful. Last year, however, he stumbled due
to a hydraulic pressure control valve used in a hydraulic climbing vehicle. At
the beginning of last year, their hydraulic climbing car was complained by
customers that it was unable to rise. During after sales service, it was judged
that the hydraulic pressure control valve was abnormal, and must be replaced.
The original manufacturer refused to be responsible, because it has passed the
1 year warranty period. Lateef was embarrassed after checking, because after
the hydraulic pressure control valves were shipped from the original
manufacturer to their warehouse, their hydraulic climbing cars were delivered
to the customer 4 month later, so the equipment was still within warranty. The
boss was unhappy, Lateef was helpless. He tried to raise the warranty period of
the hydraulic pressure control valves to 24 months to source new hydraulic
valve manufacturers, but no reply from more than 10 manufacturers that he
contacted. Lateef went from helplessness to anxiety.

Lateef found AAK on B2B and left a message on AAK website: How long is the
warranty period of hydraulic pressure control valve? I needed him to provide us
drawings for discussion. According to his hydraulic pressure control valve
drawing and working condition requirements, it is actually the standard part of
SUN hydraulics. AAK has this procedure. I asked why he requires a 24 months of
service life for the hydraulic pressure control valve, instead of requiring the
number of durability times. Then he told me the above purchasing experience and
sent me several hydraulic pressure valves from the original manufacturer. Our
engineer found during disassembly that some valve spool cylindrical surface and
conical surface, as well as the valve cage inner hole and conical surface are
not concentric, which is a problem in accuracy and affects the function. The
cone surface of some valve spool is worn, which affects the sealing, and the
performance is not up to standard. Lateef was surprised to hear this, because
no manufacturer gave him such analysis.

I told him that AAK has a similar hydraulic pressure control valve. You can
install it on the equipment for testing. If you can install it, you should not
worry about customer complaints. He was surprised and happy. More than 10
hydraulic valve manufacturers had no reply, but AAK could send samples
directly. 2 weeks later, Lateef informed that the hydraulic climbing vehicle
equipped with AAK hydraulic pressure control valve could work normally. He also
asked about the warranty period of the hydraulic pressure control valve. I told
him that AAK was benchmarking SUN, and its performance was 2 million times. As
long as the equipment was used no more than 2500 times a day, there was no
problem in 24 months.

AAK hydraulic pressure control valve, benchmarking SUN, adhere to 3 aspects,
Lateef is completely relieved.

1. The material is strictly selected. The valve spool is made of 20CrNi2MoV
from Germany. The wear resistance of the valve spool is more than 3 times that
of the material used by other hydraulic valve manufacturers. The other
manufacturers may have the performance of 500,000 to 1 million times, while AAK
has the performance of 2 million times.

2. The precision is strictly controlled. The valve hole of this model is finely
processed by American precision honing machine, and the precision of valve hole
of other hydraulic valve manufacturers is 0.8 μm - 1.0μm, while AAK can be
0.6μm - 0.8μm. The precision is increased by 25% - 30%.

3. Strict inspection, equipped with a German Test high-precision measuring
instrument for small micropore diameter, fully inspect each valve hole, while
most hydraulic valve manufacturers only conduct sampling inspection randomly.

AAK hydraulic pressure control valve, not only strict, you can also try a small
order!
