AAK hydraulic needle valve has extraordinary assembly technology

Dimon is a new buyer of a hydraulic equipment manufacturing company in the
United States. In the second half of last year, he purchased 100 hydraulic
needle valves from an old supplier. After receiving the goods, the hydraulic
needle valves were installed on the equipment. A few months later, some users
complained that the pressure supply of some equipment was insufficient. Their
technicians judged that the radial jamming of the valve spool of the hydraulic
needle valve resulted in no flow regulation, which would lead to the failure of
the power unit. The hydraulic needle valves need to be replaced with new ones
as soon as possible to eliminate user complaints. His boss is not very
satisfied that problem happened on even such a small number purchasing of
hydraulic needle valves.

Dimon is confused why the hydraulic needle valve supplier who had cooperated
for 2 years would have such quality problems. He sent some problematic
hydraulic needle valves back to the factory. The manufacturer replied that the
accuracy of these hydraulic needle valves met the standard, but a small
deviation in the size of the valve spool was caused by the deviation of the
assembler. At that time, several valves were assembled at the same time in the
assembly workshop, and a few deviations were difficult to avoid. Dimon realized
that even the original manufacturer replaced the hydraulic needle valves with
new ones, it still can not solve the problem of the radial jamming of the valve
spool for 100%. He was afraid that if there were more user complaints, could he
keep his job during the probation period?

Dimon decided to find a new supplier of hydraulic needle valves. He left a
message on our website: Can you solve the problem of radial jamming of the
valve spool of hydraulic needle valve? At first, it was hard to answer this
question. After several rounds of communication, we learned the story of his
purchase of these 100 hydraulic needle valves. After reviewing the working
conditions and drawings of hydraulic needle valve from Dimon, as well as the
pictures of hydraulic needle valves from the original supplier, AAK suggested
him trying samples directly. 20 days later, AAK sent 10 samples of hydraulic
needle valves made per his requirements.

Two months later, Dimon sent an email to us saying that he selected 5 factories
from more than 20 hydraulic needle valve manufacturers to make samples. Only
the samples from AAK and another factory did not have the problem of radial
jamming of valve spool during the test. Their engineers suggested that AAK
should be selected to replace the 100 hydraulic needle valves with potential
quality problems, because the parameters of AAK hydraulic needle valve are the
most stable. The boss knew that he dared to develop new suppliers and solved
the hidden quality problems, although the probation period is not over yet,
Dimon was approved to become a regular in advance. He told us this story
privately.

To do this hydraulic needle valve well, it needs not only high-precision
equipment, but also need to avoid personal assembly errors. AAK has technical
workers with more than 10 years of operation and production experience,
combined with advanced high-precision honing machines, CNC machine tools and
other production equipment, as well as advanced three coordinate instrument,
cylindricity instrument, profilometer and other testing equipment. The most
important thing is that AAK has specially assigned personnel to control the
assembly process of hydraulic needle valves, so as to avoid partial mixture
wrong assembly caused by cross assembly by multiple people, especially in the
assembly process of similar valve bodies. Many factories arrange cross assembly
in order to save personnel and improve efficiency, resulting in wrong assembly
of accessories. This assembly process of AAK hydraulic needle valves is unique
in the industry. Maybe there is no second factory in Ningbo, the hometown of
hydraulic valves to do this like us.

AAK hydraulic needle valves, no radial jamming of valve spool problem, welcome
to have a try!
