| Message: | Renato comes from Brazil and recently developed a hydraulic cartridge directional control valve, which caused him trouble. In May this year, their improved hydraulic power unit required customized hydraulic cartridge directional control valves. Renato chose an old supplier to make samples. The samples were recognized by their technical department except for the valve hole accuracy of the hydraulic cartridge directional control valve. After sending samples several times, the original manufacturer still failed to achieve the stable accuracy, wasting more than 60 days and had to give up. The technical department complained that Renato did not choose high-quality hydraulic cartridge valve manufacturer for this directional control valve, which made Renato very worried. |
