AAK 4 Cleaning Procedures, no residue on Hydraulic Cartridge Valves

Faraji is from South Africa, and fell down when he purchased hydraulic
cartridge valves from China in the first time. Last September, Faraji purchased
a hydraulic cartridge valve from China and used it in their hydraulic manifold.
After more than 1 month of operation, it was discovered that the hydraulic
cartridge valve was leaking, with foreign objects remaining between the valve
spool and valve seat, causing the valve to get stuck. The original hydraulic
cartridge valve manufacturer shifted the blame and said that it was caused due
to the uncleanness of the hydraulic oil. Faraji felt helpless.

I'm not sure where Faraji learned about AAK hydraulic valves. He left a message
on our website: Can AAK ensure that each hydraulic cartridge valve has no
residual impurities? There are not many messages about residual impurities in
the valve. After communication, it was learned that he encountered problems
when purchasing cartridge valves from other hydraulic cartridge valve
manufacturer in China. He may have encountered a manufacturer who does not pay
attention to quality, or always thought that African customers do not pay
attention to quality.

The hydraulic cartridge valve required by Faraji is a standard part of SUN
Hydraulics's RDDA series, and we have program for this model. In 1 week, AAK
sent out 30 samples of RDDA hydraulic cartridge valves. 6 months later, which
was last week, Faraji informed us via email that the AAK hydraulic cartridge
valve did not experience any jamming, and the valve produced by the original
manufacturer was stuck in over 1 month. I told him that no customer has
complained that the AAK hydraulic cartridge valve has stuck within 1 year. In
fact, it is not difficult to solve the residual in the hydraulic cartridge
valve, but most hydraulic cartridge valve manufacturers in China cannot do it
well.

AAK independently developed an automated ultrasonic assembly line 6 years ago,
to clean each processed component. There are 4 procedures, one linked with
another, without the need for manual labor.

1. First, degrease. We do this by immersing each component in a degreasing tank
for more than half an hour, to ensure that the surface oil stains of each
component are completely removed. Most manufacturers directly overlook this
action.

2. After oil removal, it automatically enters the ultrasonic cleaning tank. By
utilizing ultrasound, the direct inflow effect in the liquid disperses,
emulsifies, and peels off impurities on the surface of the component.

3. After ultrasonic cleaning, the components automatically enter the rust
prevention tank for rust prevention treatment, improving the corrosion
resistance of each component.

4. Finally, each component enters the automatic drying tank for drying. After
100% drying, proceed to the assembly workshop.

AAK hydraulic cartridge valves are cleaned by 4 procedures that do not require
manual operation, which not only has high production efficiency, but also
ensures 100% residue free and no worry about valve stuck.

AAK hydraulic cartridge valve, no residue, no stuck, you can also give it a
try!
