AAK Hydraulic Cartridge Relief Valve No Blockage

Ephraim comes from a hydraulic equipment manufacturing company in Chile. Unexpectedly, the hydraulic cartridge relief valve purchased at the beginning of the year stumped him. 3 months ago, they received a customer complaint that the hydraulic cartridge relief valve on the logistics transmission system of the coal yard could not be opened or closed properly, or the control was unstable. After checking, it was found that the damping hole and the slender hole of the valve cage were blocked by impurities in the hydraulic oil. 3 months after the hydraulic oil was replaced, the old problem reoccurred. The original manufacturer of the hydraulic cartridge relief valve said that the site was too dirty. The problem was not avoidable. The only solution was to replace the hydraulic cartridge relief valves regularly.

After browsing AAK website, Ephraim found that AAK had many cases of solving customers' difficult problems.
