AAK Hydraulic Cartridge Needle Valve 100% Consistent Coaxiality

Lewis is from a Greek hydraulic equipment company. He has been purchasing
hydraulic components for 3 years and has been successful. At the beginning of
the year, their customer had a trial order for 3 wheel loaders and needed
hydraulic cartridge needle valves. Lewis chose a hydraulic cartridge needle
valve manufacturer in Greek. After using the equipment for 3 months, the
customer reported that one of the equipment failed to rise, which should be due
to the abnormal hydraulic system. After disassembly, it was found that the
spool of the hydraulic cartridge needle valve was stuck in the radial
direction, which affected the axial movement of the screw. The root cause was
that the coaxiality of the spool and the cage of the hydraulic cartridge needle
valve was inconsistent. The manufacturer of the hydraulic cartridge needle
valve advised that it should be individual phenomena. But 3 weeks later, the
customer reported that the other two devices also had this problem. Lewis
realized that the coaxiality accuracy of the hydraulic cartridge needle valves
processed by the this manufacturer was not up to standard, and he must find a
hydraulic valve manufacturer with same coaxiality for each hydraulic cartridge
needle valve. But a week later, no new manufacturer took over. Lewis was very
worried.

From Google, Lewis noticed that AAK had published articles on coaxiality
processing and left a message asking: How confident is AAK about a hydraulic
cartridge needle valve with 100% consistent coaxiality? The drawing of
hydraulic cartridge needle valve is also attached, which also shows that it is
used on the loader equipment. According to the parameters and equipment
requirements, although the coaxiality is a little difficult to meet, AAK has
some experience. We suggested Lewis trying samples directly. After 40 days, 6
hydraulic cartridge needle valve samples were sent out.

Last week, Lewis sent an email. He said that the AAK hydraulic cartridge needle
valves had been installed in the equipment for more than 6 months, and the
equipment had not risen abnormally. Their customer was satisfied with the 3
sets of trial equipment and was ready to start purchasing in batches. Lewis
reminded us that for the regular order of hydraulic cartridge needle valves, we
must control the coaxiality as same as the samples. I told him that as long as
the trial order sample is approved by the customer, there will be no problem
with the regular order, because AAK hydraulic cartridge needle valve can
achieve 100% coaxiality consistency, which depends on 3 key points:

1. The equipment is advanced: AAK uses high-precision honing machine imported
from Swiss, with German cutters. The accuracy is guaranteed, and the tolerance
is not worried.

2. There are experienced operators: 30 years of technicians, special personnel
assigned for special machine, and every key point and difficulty of control are
engraved in their minds.

3. The inspection is powerful. 3 coordinate measuring instrument, control valve
spool and valve cage coaxiality detection, 100% full inspection, instead of the
select sampling inspection of peers.

AAK hydraulic cartridge needle valve, has replaced the Greek hydraulic valve
manufacturer. You can also have a small try.
