| Message: | Phoebe comes from Greece, and has been purchasing hydraulic valves from Ningbo for 2 years. At the end of last year, their hydraulic power unit required a hydraulic pressure control valve, and Phoebe tested the sample from a cartridge valve manufacturer that had been cooperating for 2 years. During debugging, the equipment was unstable in operation, and it was found on site that it was rooted in the internal cone angle error of the hydraulic pressure control valve and the excessive axial grinding tolerance of the sealing circle. The original hydraulic pressure control valve manufacturer re-made samples two times, but the machining accuracy of the hydraulic pressure control valve still did not meet the standard. Phoebe realized that she needed to change the manufacturer of the hydraulic pressure control valve. After trying with another hydraulic pressure control valve manufacturer, the problem was not completely resolved for a month, and the boss was very angry that Phoebe was in a hurry and became anxious. |
