Micro Particle Residue Stuck Hydraulic Diverter Valve, AAK Solved in 20 day

Taylor suddenly emailed us to ask if we can deliver 110 hydraulic diverter
valves within 20 days? As the purchasing manager of Caterpillar, Taylor has
cooperated with AAK for several years, but since the last half year, there has
been only inquiry and no actual order. There must be a reason for this urgent
hydraulic diverter valve order. Taylor said that the customer complained that
their excavator was weak. The hydraulic diverter valves used in the excavator
were abnormal. Their engineers found that the valve spool of the hydraulic
diverter valve was stuck, so they had to re purchase new hydraulic diverter
valves for replacement. The customer asked them to replace these hydraulic
diverter valves within 1 month. This time was very tight, and Taylor didn't
have any confidence about it at all.

The original manufacturer considered that the residues in the valve were due to
the unclean hydraulic oil used, and was unwilling to offer free replacement for
the hydraulic diverter valves. He only can accept to produce the hydraulic
diverter valves for another new order, but it would take 35 days to complete
it. After disassembling the hydraulic diverter valve, the Caterpillar engineer
found that there were a few fine metal particles left on the contact surface
between the valve spool and the valve sleeve, and no particles were found in
the hydraulic oil. These particles were caused by incomplete cleaning of the
hydraulic diverter valve after processing, but the original manufacturer still
denied it. Taylor had to contact other hydraulic diverter valve manufacturers,
including several local factories in the United States. Unfortunately, none of
them were able to complete the production of 110 hydraulic diverter valves in
20 days. This is why Taylor emailed to AAK. He regretted to save 20% of the
price, resulted in the current embarrassing situation.

We don't know whether we can complete the production of 110 hydraulic diverter
valves within 20 days. One day later, we advised Taylor that we are 90%
confident that we can complete the production of this batch of hydraulic
diverter valves. This hydraulic diverter valve is just very close to another
one that we produced for a German company. We still have the stock materials,
but only need to adjust the size slightly. This can save some time. After 20
days, the 110 excavator hydraulic diverter valves were successfully delivered,
and their company successfully replaced the hydraulic diverter valves. The
customer was very satisfied with their after-sales speed, and Taylor was
finally relieved.

AAK hydraulic diverter valve strictly controls and tests each production
process, especially the cleaning in the valve is clean. We use the ultrasonic
cleaning machine imported from Japan, which converts the sound energy of the
power ultrasonic frequency source into mechanical vibration through the
transducer, and radiates the ultrasonic wave into the cleaning solution in the
tank through the cleaning tank wall. Due to the radiation of ultrasonic wave,
the microbubbles in the liquid in the tank can keep vibrating under the action
of sound wave, destroying the adsorption between dirt and the surface of
cleaning parts, causing the fatigue damage of dirt layer and be removed, and
scrub the solid surface with the vibration of gas bubbles to achieve 100%
cleaning of each part without leaving any residue.

Although AAK hydraulic diverter valve is 20% more expensive, you don't have any
worries in use. Taylor also privately told us that after learning about this,
his boss suggested not to easily change the hydraulic diverter valve supplier.
AAK hydraulic valve is trustworthy.

AAK hydraulic diverter valve, the cleaning inside the valve is absolutely clean
and 100% residue free. You are welcome to give it a try!
