AAK Hydraulic Cartridge Directional Control Valve of High Stability

Alex, an old friend from Brazil who has worked with AAK for 5 years, sent me an email last month, asking me to help his new colleague Marvin to make samples for a hydraulic cartridge directional control valve and to work overtime urgently. It was learned that Marvin just joined the industry for half a year. The coaxiality accuracy of the hydraulic cartridge directional control valve purchased by Marvin from the local cartridge valve manufacturer in Brazil was not up to the standard, which led to the customer's complaint about the unstable operation of the hydraulic winch. Their engineer detected that the coaxiality error of the hydraulic cartridge directional control valve was 0.004mm, which caused the pressure in the fitting gap between the valve hole and the valve spool to be unbalanced, it must be replaced, but the original manufacturer gave up. The customer has been pushing for progress.
