| Message: | Lewis is from a Greek hydraulic equipment company. He has been purchasing hydraulic components for 3 years and has been successful. At the beginning of the year, their customer had a trial order for 3 wheel loaders and needed hydraulic cartridge needle valves. Lewis chose a hydraulic cartridge needle valve manufacturer in Greek. After using the equipment for 3 months, the customer reported that one of the equipment failed to rise, which should be due to the abnormal hydraulic system. After disassembly, it was found that the spool of the hydraulic cartridge needle valve was stuck in the radial direction, which affected the axial movement of the screw. The root cause was that the coaxiality of the spool and the cage of the hydraulic cartridge needle valve was inconsistent. The manufacturer of the hydraulic cartridge needle valve advised that it should be individual phenomena. But 3 weeks later, the customer reported that the other two devices also had this problem. Lewis realized that the coaxiality accuracy of the hydraulic cartridge needle valves processed by the this manufacturer was not up to standard, and he must find a hydraulic valve manufacturer with same coaxiality for each hydraulic cartridge needle valve. But a week later, no new manufacturer took over. Lewis was very worried. |

Is this a real buying request?
