The Hydraulic Cartridge Directional Control Valve with 2μm hole, AAK solved Renato's trouble

Renato comes from Brazil and recently developed a hydraulic cartridge directional control valve, which caused him trouble. In May this year, their improved hydraulic power unit required customized hydraulic cartridge directional control valves. Renato chose an old supplier to make samples. The samples were recognized by their technical department except for the valve hole accuracy of the hydraulic cartridge directional control valve. After sending samples several times, the original manufacturer still failed to achieve the stable accuracy, wasting more than 60 days and had to give up.

Renato left a message on AAK website: Can AAK finish 30 pcs of non-standard customized Hydraulic cartridge directional control valves in 30 days, with valve cage and hole accuracy within 2μm, cylindricity within 3μm and surface roughness within Ra0.2?
