AAK Hydraulic Cartridge Needle Valve use a 6 mm chamfer trick to solve Peder's equipment abnormality

Peder is from a hydraulic equipment company in Peru. They mainly focus on logistics transmission hydraulic equipment. At the beginning of this year, customers complained about the unstable control and inaccurate positioning of the lifting hydraulic power unit they sold. The after-sales server judged on site that the problem was caused by the hydraulic cartridge needle valve in the system, but after the manufacturer's inspection, the parameters of the hydraulic cartridge needle valve met the requirements. The engineer asked the original manufacturer to optimize the hydraulic cartridge needle valve, but the manufacturer was unable to do it and gave up. Peder contacted more than 10 hydraulic cartridge valve manufacturers, but none of them had solution, Peder was very anxious. 

Peder found AAK website when searching in Google, and the background showed that he stayed for 9 minutes.
