AAK Hydraulic Relief Valve is Flexible without Jamming

AAK hydraulic pilot operated relief valve adopts diamond reamer technology, and
the valve hole accuracy of hydraulic relief valve is guaranteed to be within
3μm, the surface roughness reaches Ra0.2-0.4. AAK hydraulic relief valve is
sensitive and the valve spool is not stuck. It exceeds 99% of its peers. Nick,
who has cooperated for 6 years, still orders back from AAK.

Nick is the buyer of John Deere company. He has cooperated with AAK hydraulic
valve for more than 6 years. The boss trusts him very much. Recently, a batch
of bulldozers they sold to South Africa were complained that the hydraulic
system was unable to start. The problem was that the valve body hole roundness
of the hydraulic pilot operated relief valve was poor and the valve spool was
easy to get stuck. The boss felt very strange. In the past 6 years of
cooperation with AAK hydraulic valve, there was no complaint about the
hydraulic pilot operated relief valve. After checking, he knew that Nick found
a new supplier for this hydraulic pilot operated relief valve, which is 17%
cheaper than AAK. The approval samples of hydraulic relief valve provided by
the hydraulic valve manufacturer are qualified. Unexpectedly, the accuracy of
hydraulic relief valve shipment is uneven. The boss asked Nick to contact AAK
hydraulic valve, reproduce the hydraulic relief valves, and ship them directly
to South Africa.

We were a little surprised when we received an email from Nick to purchase 100
hydraulic relief valves and ship them directly to South Africa. Nick frankly
told us that there were problems with the shipments from the original hydraulic
relief valve manufacturer and needed the help of AAK to solve the customer
complaints together. The difficulty of customer is the difficulty of AAK. We
give priority to the production of this batch of hydraulic relief valves. After
35 days, the South African customer of Nick received the replacement of
hydraulic pilot operated relief valves, and the whole after-sales process
satisfied the customer.

Nick sent an inquiry for a new hydraulic relief valve a few days ago. He
specially said that his boss asked him to take AAK as the first choice for
future hydraulic relief valves, because the quality of AAK hydraulic relief
valve has not had any quality complaints in the past 6 years. Comparing the
hydraulic relief valves produced by AAK with its peers, it will show why AAK
hydraulic relief valve is sensitive and the valve spool is not stuck, which
exceeds 99% of its peers. Nick, who has cooperated for 6 years, still orders
back from AAK.

For the machining of hydraulic relief valve hole, most peers use rigid Boring
Reamer or stepped reamer, which has high production efficiency, but the hole
accuracy is generally 7μm or above, it is difficult to stabilize on one data,
and the roughness is fluctuated at the range of Ra1.6-3.2. AAK uses the diamond
reamer to process the valve hole of hydraulic relief valve. In the grinding
process, the reamer moves regularly in circumference and axis, and the metal is
cut completely without trace with the micro edge of diamond particles. The
accuracy of the valve hole of the hydraulic relief valve is guaranteed to be
within 3μm, the surface roughness reaches Ra0.2-0.4, which almost avoids the
roundness and cylindricity errors of the valve hole, improves the coaxial
accuracy, and unifies the accuracy data. AAK hydraulic relief valve is
sensitive, and the valve spool is not stuck, exceeding 99%.

The 17% more expensive AAK hydraulic relief valve, has its unique valve hole
processing, incomparable quality. You are welcome to have a small try.
