AAK Cartridge Needle Valve Safe for 18 Months in the Desert

Castel is from Saudi Arabia, and their company mainly sells oil mining machinery. At the beginning of last year, one of their hydraulic platforms was complained, and the equipment went on strike 8 - 9 months later. After checking, it was found that the shoulder and pin hole of the hydraulic cartridge needle valve spool in the system were broken. The hydraulic cartridge needle valve manufacturer advised that the same model of hydraulic cartridge needle valve was supplied to the South American market. Within 1 year, there was no complaint. The manufacturer explained that the brittle fracture of the hydraulic cartridge needle valve spool was caused by the working conditions and working scenarios.

Castel noticed the article published by AAK in B2B that "AAK hydraulic counterbalance valves have been used in Sandstorm for 12 months, was free of corrosion”.
