For the processing of the main valve hole of the hydraulic cartridge relief valves, AAK uses a new 4-step method instead of the traditional 4-step method, which is 100% burr free. Rubio from Mexico, placed the big order 1 week after the first test order.

Regarding the burrs in the main valve hole of the hydraulic cartridge relief valves, it involves 2 parts: how to effectively avoid and remove them. How to effectively avoid is the root cause. How to remove is the symptoms. AAK focuses on the root cause, while other hydraulic valve manufacturers pay attention to the symptoms. Burr is common in machining. As for how to control the burr in the main valve hole of hydraulic cartridge relief valve, most hydraulic relief valve manufacturers ignore the dead corner in the undercut groove. No matter how to clean it, the pain point of "black under the light" cannot be solved.
