AAK hydraulic threaded cartridge valves, no complaints among 20 suppliers

Walt placed an order for 1000 hydraulic threaded cartridge valves at one time
last week, which surprised me. Three years ago, I met Walt from an American
company at the Shanghai PTC exhibition. He communicated with us at our booth
for more than half an hour. After the exhibition, Walt sent an email saying
that his company happened to have a newly developed hydraulic equipment, which
needs to use hydraulic threaded cartridge valves. He asked AAK to urgently
provide 30 samples of hydraulic threaded cartridge valves according to his
drawings. AAK sent out 30 hydraulic threaded cartridge valves after 25 days.
After this, there was no inquiry for any hydraulic threaded cartridge valves
from him. Half a year later, Walt sent a new test order of 40pcs for another
new hydraulic threaded cartridge valve. Same as last time, there is no further
news after delivery. In this way, we just received 2 test orders in about 2
years.

I thought that there should be a mistake on the quantity of this large order of
hydraulic threaded cartridge valve this time. After several rounds of emails,
we know the story for this hydraulic threaded cartridge valve. Their company
has only begun to purchase hydraulic valves from China in recent 3 years. For
the hydraulic threaded cartridge valves purchased at the beginning, there are
always complaints from customers after a period of time, such as leakage or
jamming, insensitive opening and closing or serious wear and tear, etc. In the
past 2 years, Walt also tried samples from more than 20 hydraulic valve
manufacturers. The same problems still occur after each replacement. Only AAK
hydraulic threaded cartridge valves have not received a complaint.

Walt compared more than 20 suppliers for 2 years, and only AAK hydraulic
threaded cartridge valves had no complaints. This time, he strongly suggested
his boss that the future hydraulic threaded cartridge valves can only be
purchased from AAK. His boss also wants to know why AAK can ensure that there
are no complaints about the hydraulic threaded cartridge valves.

AAK hydraulic valve not only has the CNC machining center imported from
Switzerland, but also has its own upgraded and refitted independent fixtures,
which eliminates man-made errors. At the same time, we have accurately
controlled every detail of the processing, production, assembly, inspection and
packaging of each hydraulic threaded cartridge valve, which has surpassed the
vast majority of domestic peers.

Firstly, AAK will divide the installed products into several assembly units
according to the structure and process characteristics of the hydraulic valve,
reduce the single parts entering the general assembly as much as possible, and
ensure the reasonable assembly sequence and specified assembly accuracy of the
hydraulic valve. All parts will be accurately measured, strictly inspected and
tested before and after the general assembly of the hydraulic threaded
cartridge valve.

Secondly, AAK adopts the matching method for assembly, which will divide the
parts into several groups according to the strict size range, and then assemble
the corresponding matching parts together to achieve the required assembly
accuracy.

Finally, after assembly, check whether there is surplus or lack of parts,
whether each connecting part is loose and skewed, and whether the residue of
sealing belt on cone plug is removed. At the same time, test each hydraulic
threaded cartridge valve, including leakage, flexibility, opening and closing
performance, etc.

AAK hydraulic threaded cartridge valve is free of complaint. Welcome to have a
small try!
