For hydraulic directional control valves in extreme environments, the service life of AAK is twice t

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 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?

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?
