AAK Parallels hydraulic check valve and hydraulic throttle valve

Duden is from Lukas hydraulic equipment company in Germany. We have cooperated
for more than 2 years on hydraulic check valves and hydraulic throttle valves.
The order volume is small each time, but the parameter requirements are very
high. AAK never despised it because of the small order quantity of the
hydraulic check valves or hydraulic throttle valves. At the end of last year,
their company developed a new hydraulic unit. Due to time constraints, Duden
purchased hydraulic check valves and hydraulic throttle valves from local
hydraulic valve manufacturers in Germany. The technicians found the original
design defects after installing the integrated valve into the equipment. The
position of the hydraulic throttle valve next to the hydraulic check valve is
high, accounting for a little position of the motor, which makes it difficult
to install the motor.

Lukas engineers are a little depressed. If the position of the hydraulic
throttle valve is changed, the whole oil circuit layout needs to be changed,
but the power supply of the hydraulic system will be affected after changing
the oil circuit. What is more troublesome is that there is not much time to
redesign and proofing. The Engineers asked Duden to contact some local
hydraulic valve manufacturers to check if the design size of the hydraulic
throttle valve could be slightly adjusted so that the motor could be installed.

Duden checked with several local hydraulic valve manufacturers, all of them
were not willing to make samples because of small quantity of the hydraulic
throttle valves. Duden tried to purchase small-size hydraulic throttle valves
from China to solve the installation problem of the motor. Some Chinese
hydraulic valve manufacturers said that they could make samples according to
the requested size of their hydraulic throttle valves, but the time needed was
more than 30 days. Duden couldn't accept this time and was more worried about
the quality of hydraulic throttle valves from these factories. Duden sent an
email to AAK asking if we could make several samples of hydraulic throttle
valves in 5 days. In the past, the sample time gave by Duden was usually
flexible with more than 2 weeks. After asking, I learned that their designers
are facing embarrassment.

It is also too tight for us to make several hydraulic throttle valves in only 5
days. I suggest Duden give us the overall layout of the integrated valve block.
Maybe our engineer has a solution. According to the hydraulic schematic diagram
provided by Duden and the specific use of the hydraulic integrated valve block,
AAK engineers analyzed it step by step. Finally, it was found that if the
hydraulic throttle valve and the hydraulic check valve were designed in
parallel, the functions of the two valves were combined to form a hydraulic
throttle check valve, which was installed at the position of the hydraulic
check valve, and the installation hole of the hydraulic throttle valve was
blocked with a plug. This not only saves the redesign time of the hydraulic
integrated valve block, avoids the embarrassment that the motor can not be
installed, but also has no impact on the pressure supply of the hydraulic
system. Their designer was surprised that AAK used this idea to solve the pain
point. He hoped that we could make the samples to test as soon as possible.

AAK sent the newly designed hydraulic throttle check valve to Duden. After
installing the hydraulic throttle check valve into the integrated valve block,
the results were as described by AAK, and the test was successful. The design
engineers of Lukas company admire AAK unique design scheme and production
capacity greatly.

AAK hydraulic throttle check valve can efficiently and timely solve problems
for customers. Welcome to give it a try!
