AAK Hydraulic Cartridge Check Valves of High Quality

1 year ago, Ferdinand from Germany left a message on AAK Hydraulic Valve
website: Is there a hydraulic cartridge check valve equivalent to HydraForce?
Ferdinan bought two hydraulic cartridge check valve samples from the model
number I provided, then there was no news. Three months later, he bought
another two samples of hydraulic cartridge check valves equivalent to SUN. Six
months later, he sent a customized hydraulic cartridge check valve drawing and
brought 6 samples, there was no email for 6 months. I think it's a bit
abnormal, but if something is abnormal, there must be evil. He bought hydraulic
cartridge check valve samples from AAK 3 times a year to test my patience and
inspect the manufacturing quality of AAK. I can only comfort myself in this
way.

Last month, Ferdinand sent an email asking about the lead time for 1,200 pcs of
hydraulic cartridge check valve customized last time. I knew that AAK had
passed the investigation period of German customers. After communication, I
learned that the hydraulic cartridge check valves that he purchased in Ningbo 2
years ago, were tested with 6 hydraulic valve manufacturers before and after.
Either the first sample was OK, but the second one was not up to standard;
Either the existing valve was tested OK, but the customized valve was abnormal.
Time was wasted and delayed their equipment development. It turns out that
Ferdinand was feared by some hydraulic valve manufacturers, so he was prudent
to select new hydraulic valve manufacturers.

This time, they will develop a hydraulic boarding bridge, which requires non-
standard hydraulic cartridge check valves. From trial order to large order, AAK
has been investigated for more than 1 year. Ferdinand said that the
manufacturing quality of AAK hydraulic valves, whether the ones benchmarking
international brands or non-standard customized ones, had been recognized by
their engineers for their functions and performance, so they decided to place
large quantity order of hydraulic cartridge check valves.

The reason why AAK hydraulic cartridge check valve is different from other
hydraulic valve manufacturers in Ningbo is that we insist on the quality of
manufacturing.

1. Not make do with the equipment. No matter CNC machining center or machine
tool, only high-precision ones are selected. At the same time, the fixture is
upgraded and modified by ourselves, eliminating human error.

2. Materials should be paid attention to. Different kinds of imported high
carburized bearing steel should be combined with AAK's proprietary heat
treatment process. The hardness of the material has gone up several steps, and
its wear resistance has been improved by more than 3 times. The thermal
stability and compressive strength of materials have been far ahead of other
hydraulic valve manufacturers.

3. The inspection is vigorous. The high-precision test bench and durability
test equipment independently developed by AAK are used to conduct 100% full
inspection. The pressure, flow and fatigue resistance of the valve cannot
escape Sun Wukong's eyes.

AAK hydraulic cartridge check valve, insists on high quality. You can also have
a small try!
