AAK Hydraulic Cartridge Directional Control Valve Service Life Twice its Peers

Ibeamaka is from a hydraulic equipment company in Pakistan. At the beginning of last year, their hydraulic packer was complained by customers. The leakage of the hydraulic cartridge directional control valve in the system caused the equipment to work weakly, which was caused by the wear of the valve spool end. The original manufacturer of the hydraulic cartridge directional control valve said that because the system was opened and closed frequently, even if the valve spool of the bearing steel was worn, it was inevitable, so the service life of the hydraulic cartridge directional control valve could only be within 1 year. The boss was not satisfied with the original manufacturer's after-sales guarantee of more than 9 months, and requested to change the manufacturer, and the service life of the hydraulic cartridge direction control valve should not be less than 18 months.
