AAK hydraulic relief valve is resistant to high pressure and is not stuck

Ernst is from a German hydraulic equipment company. He has been doing well in
recent years, and his boss is optimistic about him. The hydraulic relief valves
purchased this time has suffered a big setback. In the second half of last
year, the hydraulic power unit sold by their company for less than 3 months was
complained by customers. When the pressure of the hydraulic relief valve was
adjusted to 450bar, the equipment idled. The engineer thought that it could be
solved by changing the motor. As a result, after the equipment started for a
while, the same situation happened again. The engineer checked each component,
and it turned out that the spool of the hydraulic relief valve was stuck. After
the boss knew about it, he asked Ernst to request the original hydraulic relief
valve manufacturer to solve the problem and bear the motor cost twice. Per the
manufacturer, the price of the hydraulic relief valve is too low this time.
Under the high pressure of 450bar, it is difficult to avoid a few stuck
occasionally, then there is no further news.

Ernst had no choice but to find new hydraulic relief valve suppliers. Ernst
contacted more than 10 factories and requested that the hydraulic relief valve
be 100% free of jamming within 1 year under the high pressure of 450bar. Only
two factories were willing to cooperate with the samples, and other
manufacturers gave up directly. Ernst still seemed worried about wasting time.
With the introduction of his friend Steven, who is our old customer, he
contacted AAK hydraulic valve. Ernst asked us to make samples directly
according to his hydraulic relief valve drawings and working conditions. The
key of this hydraulic relief valve is how long the service life of the
hydraulic relief valve is under 450bar high pressure? Actually, AAK has already
mass produced hydraulic valves with similar requirements.

Nine months later, Ernst informed by e-mail that the hydraulic relief valve
from one factory had been on strike because of its stuck, and the other
factory's, although still working, it was estimated to be less than 12 months.
After 9 months of use, the parameters of AAK hydraulic relief valves are still
stable and function normally. Ernst said that compared with more than 10
factories, AAK high-pressure hydraulic relief valve has the most stable
performance and longest service life among all the manufacturers he knows.
Ernst estimated that he would not need to change the hydraulic relief valve
suppliers any more.

AAK hydraulic relief valve has 3 advantages and has already surpassed its
domestic counterparts.
 
1. AAK has a high-precision CNC machining center imported from Switzerland and
its own upgraded and refitted independent fixture, which eliminates human
errors. The high-precision control of component processing is the key point to
prevent jamming.

2. AAK has engineer team with over 10 years of technical experience,
independent professional research and development, with unique research and
development technology, select the raw materials and spare parts according to
the working conditions of customers' actual needs. The selection of materials
is the key to determine the service life of the hydraulic relief valves.

3. Through EasyForm software, AAK can accurately and quickly measure each
valve component to ensure that the concentricity of each hydraulic relief valve
is 100% consistent and prevent jamming. Detection is the final check on the
quality control of the hydraulic relief valves.

AAK hydraulic relief valve is resistant to high pressure and has no jamming.
