AAK Hydraulic Flow Control Valve Increases System Efficiency by 5%

The supplier who have cooperated for 4 years have failed to solve the problem
of valve hole deformation caused by the assembly force of hydraulic flow
control valve for 4 times of proofing. After AAK changed the process, not only
did the accuracy of the hydraulic flow control valve hole reach the standard,
but also the operating efficiency of hydraulic system equipment was improved by
5%. This is the first time for Thomas to receive such a surprise from a Chinese
hydraulic valve manufacturer.

Thomas is from a hydraulic company in the United States. He has been in contact
with me for 3 years. In addition to quoting prices and sending hydraulic valve
samples several times, he has never placed an order. I laugh at myself that
fate has not come. 3 months ago, a PO for hydraulic flow control valve worth
more than 20,000 US dollars was sent to us suddenly, which scared me. It was
turned out that a supplier who had cooperated with him for 4 years, could not
solve the problem of this hydraulic flow control valve even after 4 times of
proofing. Under the assembly force of 90N • m * 4, the deformation of the valve
hole reached 0.013mm, which did not meet their accuracy requirements, and the
original manufacturer had to discuss the delivery date again because of the
several failures of the hydraulic flow control valve samples. Thomas realized
that the manufacturer had to be replaced, so he contacted AAK.

Thomas said that he had been tracking AAK for the past 3 years because his
company required that any new supplier should have a 3-year investigation
period. Every time AAK sent samples, he would be surprised. He also looked
forward to the surprise of the hydraulic flow control valve this time - the
sample time and the sample quality. He also reminded me that several suppliers
have given up to try directly before he chose the current supplier. I realized
that this hydraulic flow control valve PO was a hot potato. If it was messed
up, the fate of 3 years would be zero.

Is it a surprise or a fright? We have to fight. The AAK technical team
separated the drawings of the hydraulic flow control valve step by step and
realized that it was really difficult to process this hydraulic flow control
valve, but they also had ideas. 3 weeks later, the master of the sample fed
back that the deformation of the hydraulic flow control valve bore was still
not up to the standard. Moreover, excessive wear of calipers and oilstones
leads to low honing efficiency, and the scrap rate reaches 3%. Even if the
sample is successful, the mass production is also a hidden danger, and the
production process must be changed. After 5 days, the master tried to pre
assemble the hydraulic flow valve body and left it for 2-3 days. Before honing,
rough reaming with diamond reamer is used to correct the roundness deviation of
the valve hole of hydraulic flow control valve due to assembly preload and
creep. The whole honing time is shortened from 210s to 60s. With the improved
production process, the production efficiency was increased by 150%, and the
scrap rate was reduced to 0.5%. After 5 weeks, 12 hydraulic flow control valve
samples were sent out.

2 weeks later, Thomas informed by email that the technical parameters of AAK
hydraulic flow control valve had been confirmed, especially the accuracy of the
valve hole, which surprised him. For the hydraulic flow control valve that the
original manufacturer could not fix for 4 times, AAK was successful at one
time. What made his engineers more happy was that the operating efficiency of
the hydraulic system of the equipment equipped with AAK hydraulic flow control
valve increased by 5%. This is the first time to receive such a surprise from a
Chinese hydraulic valve manufacturer.

AAK hydraulic flow control valve brings only pleasantly surprise, not
frightening surprise. You can also have a small try.
