AAK Hydraulic Cartridge Valve Cage Burrs Removing Method

A while ago, someone left a message on the website of hydraulic cartridge valve manufacturer AAK: How do you handle the fine burrs on the edges and corners of the hydraulic cartridge valve cage? This is a detailed issue that is often overlooked by most hydraulic cartridge valve manufacturers. Although his IP comes from Greece, I was not sure if he is a peer of hydraulic cartridge valve manufacturers or a purchaser. After two rounds of communication, it was learned that Apollo is an engineer from a hydraulic equipment company in Greece. They have been purchasing hydraulic components from hydraulic cartridge valve manufacturers in China for 3 years, and there are always some defects, such as residual burrs on the edges and corners of the hydraulic cartridge valve cage. They often have to manually handle these burrs, which has delayed their production progress and is very helpless.
