AAK Cartridge Solenoid Valve Wear-Resistant for 3 Years

Kaka is from Brazil. When he left a message and his signature on AAK hydraulic
valve website, I thought of Kaka playing football. He encountered confusion
about the service life of the locally purchased hydraulic cartridge solenoid
valve. Their hydraulic power unit requires the use of a hydraulic cartridge
solenoid valve benchmarking HydraForce, and he purchased the existing copy
stocks from a local hydraulic valve manufacturer in Brazil. 6 months later,
there were complaints about severe wear and leakage of the cartridge solenoid
valve body. The original cartridge solenoid valve manufacturer said that due to
poor working conditions, the only solution is to replace the valves with new
ones. But it wasn't long before the old problem recurred. The customer was very
dissatisfied and requested that the service life of the cartridge solenoid
valve be at least 1 year, but the original manufacturer did not cooperate,
making Kaka anxious.

Kaka discovered AAK hydraulic valve on Google and left a message asking: Can
AAK ensure that the service life of the cartridge solenoid valve is at least 1
year under high friction and high-frequency use? Especially the cartridge
solenoid valve body needs to be wear-resistant. Upon seeing this message, I
speculated that the selection of materials for the original cartridge solenoid
valve was not targeted and only followed the industry standards. After
communication, it was learned that he encountered the dilemma of the valves not
being wear-resistant when purchasing from local hydraulic valve manufacturer in

This model is a HydraForce standard part and AAK have it in stock. But for his
working conditions, we cannot simply use 40Cr alloy steel to produce the body
of this cartridge solenoid valve. Kaka may have realized that I came to the
point and requested AAK to make 30 samples of the cartridge solenoid valves
first. 2 weeks later, AAK sent out the cartridge solenoid valve samples.

Last week, Kaka placed a PO for 360 cartridge solenoid valves, which indicates
that AAK hydraulic cartridge solenoid valve has passed the test with a service
life of over 1 year. After confirming the delivery time for the first order, he
told me that the customer is very satisfied with AAK cartridge solenoid valve,
which is not only wear-resistant, but also leak free, and has no abnormalities
within 1 year.

We have chosen high-strength alloy steel instead of the industry's 40Cr alloy
steel to produce the body of this cartridge solenoid valve. The surface
treatment of steel adopts electromagnetic induction heating, and the surface
oxidation and decarburization of the workpiece are relatively light. The
surface hardening layer is easy to control, and the hardness and toughness are
high, increased by more than 30% compared to conventional heat treatment
processes. Especially during induction heating surface quenching, the workpiece
generates internal stress and improves its fatigue resistance. Therefore, the
wear resistance of high-strength alloy steel treated in this way is 8-10 times
that of the original 40Cr alloy steel. In the wear-resistant aspect, AAK
cartridge solenoid valve can be used for 3 years without any trouble.

AAK hydraulic cartridge solenoid valve, wear-resistant for 3 years without any
trouble, you can also give it a try!
