AAK Hydraulic Cartridge Directional Valve Cylindricity Accuracy 2μm

David from Israel collaborated with hydraulic cartridge valve manufacturers in China since 2018. AAK has supplied him with several hydraulic cartridge proportional valves that are equivalent to HydraForce standard parts, and it has always been very smooth. In May of this year, a hydraulic cartridge directional valve with high requirements for cylindricity made him very upset.

This hydraulic cartridge directional valve is used in hydraulic systems for navigation, with high accuracy requirements, especially the cylindricity accuracy cannot exceed 3μm. David disliked the high price of AAK, and chose another hydraulic cartridge directional valve manufacturer in Ningbo China. Later, I learned that it was just 12% higher. I told David that there are no more than 3 manufacturers in Ningbo that have this program.
