AAK hydraulic relief valve uses quenching process to ensure 0.3mm finishing

Logan has been a purchaser of a hydraulic company in the United States for
several years, and the purchasing of hydraulic valves in China is also very
smooth. But recently, a high-precision hydraulic relief valve order worth more
than $30,000 wasted him a lot of time. The original hydraulic relief valve
manufacturer made the samples twice, but was still not approved by the
customer. His customer understood that the original manufacturer was unable to
meet the requirement of 0.3mm finish size allowance, and asked him to change
the hydraulic relief valve manufacturer to make samples for the third time. If
the hydraulic relief valve sample for the third time still cannot be approved,
the customer can only cancel the order. This order attracted the attention of
his boss, who asked him to solve the problem and get the sample of hydraulic
relief valve approved at one time within 20 days.

Five days later, Logan consulted many hydraulic relief valve suppliers, and
most manufacturers said that they could not meet the standard of 0.3mm
finishing size allowance. Logan is a little worried. He looks for hydraulic
relief valve manufacturers everywhere on the Internet. He left a message on our
AAK website: how can we guarantee the finishing dimension allowance? All such
messages are basically for difficult problems encountered in the purchase of
hydraulic valves. After some communication, it is understood that the Logan was
stuck on the sample approval process of the hydraulic relief valve order, and
he has contacted many hydraulic relief valve manufacturers, but no solution has
been obtained.

I suggested Logan try our sample directly, and let the test data to speak for
itself and this also saves time. Logan doesn't seem to have a choice but to
expect that maybe AAK hydraulic relief valve can pass the test. A week later,
AAK sent out 3 hydraulic relief valve samples. Logan did not dare to send the
samples to the customer directly after receiving them, so he had to find a
third party for testing before sending them to the customer. Without incident,
the customer approved AAK hydraulic relief valve samples. His boss was also
surprised that how a hydraulic relief valve manufacturer found by Logan this
time can solve the problem so quickly at one time.

The heat treatment process in the early stage is the first step of finishing
the size allowance. Most hydraulic relief valve manufacturers adopt local
quenching, so the heat treatment process of the workpiece is not easy to
control and may be deformed. As early as 6 years ago, AAK adjusted local
quenching to overall quenching. At the same time, vertical flow treatment must
be required for the hoisting mode in the process of quenching and tempering, so
as to minimize the influence of tissue stress and thermal stress on deformation
during workpiece heat treatment, so as to meet the requirements of dimensional
allowance for finishing.

Logan cancelled the order with the original hydraulic relief valve manufacturer
without hesitation and confirmed the order with AAK hydraulic valve in two
rounds. Logan privately told us that his customers like the hydraulic relief
valve manufacturers such as AAK very much. The customer pointed out that AAK
should be as the priority supplier for future inquiry of hydraulic relief
valves. His boss was also very satisfied with his ability to quickly solve
problems this time, and put higher and higher expectations on him.

AAK hydraulic relief valves, strictly controls the size allowance of finishing
to ensure the accuracy of products. You can also have a small try!
