AAK Hydraulic Valve Use 100% Imported Pressure Spring, Natalia Admired

5 years ago, AAK hydraulic pressure valves started to use 100% Korean piano
steel wire as the pressure spring of hydraulic valves, while only a few
hydraulic valve manufacturers in Ningbo were using it. Russian customer Natalia
placed an order 3 months after receiving our hydraulic pressure valve samples.
Finally, AAK HYDRAULIC VALVE became Natalia's only hydraulic valve supplier in
Ningbo.

Most hydraulic valve manufacturers use carbon steel, which is cheap and widely
used, as the valve spool of hydraulic valves. This pressure spring has good
hardness, but its plasticity and toughness are very general, its tensile
strength is relatively weak and its stability is difficult to control. After
the hydraulic pressure valves being used for a period of time, the pressure may
not be adjustable.

Natalia, a Russian customer, purchased hydraulic pressure valves from Ningbo
last year. There was a problem with the automatic pressure regulation. She
received many complaints from her customers. Natalia contacted more than 10
hydraulic valve manufacturers, but all the pressure springs from them were not
up to standard. Natalia thought of AAK HYDRAULIC VALVE, which may be able to
solve this problem. When we received the hydraulic pressure valve drawing from
Natalia, she repeatedly stressed the quality of the pressure spring. After
discussion, the technical team of AAK HYDRAULIC VALVE promised to send the
approval sample of hydraulic pressure valve within 12 days.

After we sent the hydraulic pressure valve sample, Natalia only confirmed the
receipt and asked us to wait for her comparison results. We have been waiting
for 3 months, during which time we sent an email to her, but didn't get a
reply, so we held this hydraulic pressure valve.

The day before our National Day holiday, I was a little surprised when I
received an email from Natalia for the hydraulic pressure valve order. In the
following conversation, we learned that she had not only asked us AAK HYDRAULIC
VALVE factory to make samples. She contacted with more than 10 hydraulic valve
manufacturers totally, and asked 3 manufacturers to make samples and send the
samples to their company for testing. The company tested every components and
the circulation of the whole hydraulic system. We AAK HYDRAULIC VALVE and
another hydraulic valve manufacturer from Guangdong were shortlisted. However,
the pressure spring of AAK hydraulic pressure valve has unique skills, and its
tensile test parameters are the best. Natalia chose AAK HYDRAULIC VALVE
finally. She said that if the quality of this order is no problem, AAK
HYDRAULIC VALVE will be their only hydraulic valve supplier in Ningbo in the
future.

AAK hydraulic valves have always used piano steel wire pressure spring imported
from Korea. The material has high strength, good elasticity, fatigue
resistance, creep resistance and toughness, smooth and clean surface, strong
anti rust ability, specified tensile strength and torsional performance, and
the surface will not have cracks, folds, scabs, tensile cracks and corrosion.

AAK hydraulic valves are not the common quality in the market, but it is the
one that is difficult for you to find several hydraulic valve manufacturers in
China that can be compared with us. It's not because we are pride, we're more
honest and just tell the truth. You can also try a small order.
