AAK hydraulic relief valve has benchmarked with German HAWE

According to the financial dept this morning, there was a sample fee for
hydraulic pilot-operated relief valves. I knew it was from ROQUET company in
Spain. One year ago, Domingo in their company had a hydraulic pilot-operated
relief valve that needed AAK to make samples, but was unwilling to pay $2,000
of the sampling fee. The original factory didn't need them to pay, so they
chose that factory to produce this hydraulic pilot-operated relief valve. Last
week, Domingo came to me again to ask if there was time for sampling and they
would pay the sampling fee.

After communication, it was learned that the hydraulic pilot-operated relief
valves shipped by the original factory were used in the hydraulic power unit.
Less than half a year, it was reported for repair by the customer. It is easy
to have insufficient power supply of the hydraulic system during the
construction process. The after-sales engineer found that the wear of the valve
spool of the hydraulic pilot-operated relief valves led to leakage. He had to
use the alternative pilot-operated relief valves first and asked Domingo to
contact the original manufacturer to solve the problem. The original
manufacturer reported that the hydraulic pilot-operated relief valves had not
been worn for more than 1 year previously. The working pressure is more than
450bar this time. The domestic hydraulic pilot-operated relief valves can only
have a service life of half a year. If you want to find a hydraulic pilot-
operated relief valve with a service life of more than 1 year, you can only buy
it from HAWE in Germany. They are the best manufacturer of hydraulic pilot-
operated relief valves with high pressure resistance in the world, but the
price is estimated to be more than twice that of Chinese manufacturers.

Domingo was a little helpless and asked the boss whether to purchase directly
from HAWE in Germany or continue to look for hydraulic pilot-operated relief
valve manufacturers in China. Because the alternative hydraulic pilot-operated
relief valves were used on the construction site, they still had a 6-month
buffer period. The boss asked him to look for the hydraulic pilot-operated
relief valves under high pressure at the same time. At this moment, he thought
of AAK. When I told him that the key point of the service life of this
hydraulic pilot-operated relief valve is to resist high pressure, AAK has an
engineer who has worked in HAWE Shanghai factory for 8 years, our production of
high-pressure hydraulic valves is just to benchmark with that of German HAWE
company, he seems to realize that perhaps AAK can sample a hydraulic pilot-
operated relief valve with a service life of more than 1 year this time.

AAK replied that it could complete the samples of 12 hydraulic pilot-operated
relief valves within 1 month, and the warranty was more than 1 year. Domingo
remitted the sample fee of US$2,000 the next day. I asked him why he was
unwilling to pay last time, but this time he immediately paid the sample fee of
the hydraulic pilot-operated relief valves. He was frank about two points.
First, AAK mentioned the key points for the success of the sample. Second, AAK
high-pressure hydraulic pilot-operated relief valves benchmarked with German
HAWE company.

The reason why AAK can tell the key points and why it can benchmark with German
HAWE company is that there are two key points of AAK pilot-operated relief
valves. It may be difficult to find the second manufacturer of hydraulic valves
in Ningbo.

1. The valve spool of AAK pilot-operated relief valve is ETG100 produced by
STEELTEC company of Switzerland, which is easy to cut and has high strength. It
is suitable for high-speed CNC processing, and the strength of each section
inside and outside the material is consistent. After the valve spool is
processed into shape, the strength will not be affected.

2. AAK has a high-precision CNC machining center imported from Switzerland.
After the engineers set the program, they can control the steel processing
efficiently and without mistakes. Not only the strength is not affected, but
also the accuracy is guaranteed.

AAK hydraulic pilot-operated relief valve is used for working pressure above
450bar. You can also have a small try!
