For hydraulic directional control valves in extreme environments, the service life of AAK is twice that of other hydraulic valve manufacturers

Renzo is from Italy. As an old purchaser of the company, he has been doing very well before. The hydraulic directional control valves purchased at the beginning of last year distressed him. One of their high-pressure hydraulic supports had leakage due to corrosion of the hydraulic directional control valves 6 months after sales, resulting in instability of the support. The original hydraulic directional control valve manufacturer thinks that the corrosion is caused by the extreme working environment and cannot be completely improved. Renzo realized that trouble was coming and began to contact the new hydraulic directional control valve manufacturers. However, after 2 weeks, no hydraulic valve manufacturer guaranteed that it would not corrode for 1 year in an environment with high sulfur and wax oil content and low temperature, Renzo was worried.

 

Renzo found AAK hydraulic valves in Google and left us a message: can you produce hydraulic pressure control valves that can guarantee non corrosion in extreme environments for more than 1 year? I told him that it depends on the working environment and the drawing requirements of the hydraulic directional control valve. According to the information provided by Renzo, after 1 day of discussion, AAK technical team is 90% confident to be successful. Maybe Renzo had no choice, and paid the development fee the next day.

 

Material selection is the key to solve corrosion. After 3 times of material selection and 6 times of testing, AAK technical team completed and sent 24 samples of hydraulic directional control valves 60 days later. Last week, Renzo informed by email that it had been 10 months since their hydraulic support was installed with AAK hydraulic directional control valve, and there were no complaints of corrosion and leakage. I told him to be relieved that there would be no complaints within 1 year.

 

Why did the AAK hydraulic directional control valve is corrosion-resistant for more than 1 year, while the other hydraulic valve manufacturers failed in 6 months?

 

Monel 400 alloy steel is selected for this hydraulic directional control valve. The material is based on nickel metal, and copper, iron, manganese and other elements are added. Its corrosion resistance is more than 3 times that of conventional steel, especially in the geological exploitation of high sulfur and high wax oil reservoirs. At the same time, its mechanical properties have been improved by more than 30%, and it is friction resistant in low temperature environment. Besides, Monel 400 alloy steel has another feature, which is not easy to produce stress corrosion cracks, and is mostly used in aerospace, marine and oil and gas industries. Although the material cost is 2-3 times higher, AAK needs to choose the best option. Even if it's 2-3 times more expensive, still choose the best. Because AAK can't make things that are not good enough, let alone supply them to consumers.

 

AAK hydraulic directional control valves, material selection with heart, you can also have a small try!
