AAK Hydraulic Cartridge Valve Corrosion-Resistant for over 1 year

Manator is from Indonesia and has been engaged in the procurement of hydraulic components for 2 years. At the beginning of last year, the hydraulic power unit they sold for deep-sea oil drilling was complained of as abnormal by customers 6 months later. The root cause is severe corrosion on the surface of the hydraulic cartridge valve in the hydraulic system, leading to dysfunction of the hydraulic cartridge valve. Manator was very confused because the valves sold to other markets from the same batch production has no complaint for over 1 year. The original hydraulic cartridge valve manufacturer stated that the corrosion in deep sea is severe, and the only solution is to replace the corrosive valves with new ones, and the service life can be only guaranteed for 6 months or less.
