Brighton is from Brazil and has cooperated with AAK for 3 years. Most of the orders are for non-standard customized hydraulic cartridge valves. At the beginning of this year, he inquired about a hydraulic cartridge pressure control valve of HydraForce standard parts, and advised that AAK price was 20% higher, then no further updates. I guessed either he didn't get the order, or he gave it to another hydraulic cartridge pressure control valve manufacturer, and I didn't follow up for the status.

 

In October, Brighton sent an email to inquire about this hydraulic cartridge pressure control valve again. After communication, I learned that Brighton chose a hydraulic cartridge valve manufacturer that was 20% cheaper than AAK to place the order at the beginning of the year. However, more than 8 months later, customers complained that the hydraulic cartridge pressure control valve was leaking or stuck. However, the manufacturer did not offer good after-sales service, which made Brighton embarrassed and regretted being greedy for cheap. Brighton returned to AAK, and requested the valve service life to be no less than 16-24 months. I joked that, during the 3 years of cooperation with AAK, did you see any AAK hydraulic cartridge valve with a service life of only 1 year? It is a fact that AAK hydraulic cartridge pressure valve is 20% more expensive, but its service life is twice that of its peers.

 

After 1 week, Brighton sent the PO for 360 hydraulic cartridge pressure control valves, and specifically mentioned that his boss was interested in the service life of AAK hydraulic cartridge pressure valve being twice that of peers, not that the price was 20% higher than that of the original manufacturer. I told him that the price of AAK hydraulic cartridge pressure control valve was 20% higher, not only because the raw materials and accessories were 1-2 grades better than those used by peers, but also the heat treatment of metal parts was great, and special components used AAK personalized heat treatment process. The heat treatment process is carried out under vacuum, including quenching, annealing, tempering, carburizing and nitriding. This heat treatment process has 3 advantages:

 

1. When heated under vacuum, the metal elements will not be oxidized, decarburized or carburized, the surface finish will be improved by at least 30%, and the strength of steel parts will also be improved, making them more wear-resistant.

 

2. Under vacuum heating, the hydrogen in the metal is rapidly reduced to the minimum, eliminating hydrogen embrittlement, improving the plasticity, toughness and fatigue strength of steel, and the overall mechanical properties of the components are more conducive to the life of the hydraulic cartridge pressure control valve.

 

3. The furnace is heated by thermal radiation, the temperature difference between inside and outside is small, and the quenching under vacuum ensures that the hardness of each element is consistent, which is also conducive to the service life of the hydraulic cartridge pressure control valve.

 

AAK hydraulic cartridge pressure control valve is 20% more expensive, but its service life is twice that of its peers. You can also have a small try!
