AAK Hydraulic Directional Control Cartridge Valve Twice Service Life of its Peers

Erasmus is from a hydraulic equipment company in Colombia. He has been purchasing smoothly, but a batch of hydraulic cartridge directional control valves stumped him. The loader sold by their company less than 1 year has been complained of shaking. During after-sales service, it is found on the site that valve spool of hydraulic cartridge directional control valve is stuck during operation, which is caused by deviation of valve hole accuracy. The original manufacturer advised that there should be not many pieces of hydraulic cartridge directional control valve was stuck and could be replaced, but there were more and more complaints later. The boss was not satisfied with Erasmus's purchase this time, asked him to replace the manufacturer of the hydraulic directional control cartridge valve, and requested that service life of valve be more than 18 months. Erasmus contacted more than 10 cartridge valve manufacturers.
