| Message: | Eugenia comes from Greece, and has been smooth on purchasing for 5 years. Unexpectedly, due to a hydraulic manifold, she was in a trouble. At the beginning of this year, their company developed a hydraulic station for elevator lifting systems for the first time, which requires hydraulic manifold. Eugenia chose a manufacturer that has been cooperating for over 3 years to make samples, and the sample testing went through smoothly. The first batch of 50 hydraulic stations, after 2 months of operation, occasionally experienced abnormal elevator operation. The after-sales engineer found that there was a leak in the hydraulic manifold within the system, and some pressure control cartridge valves have hysteresis in opening and closing. Per the manufacturer of the hydraulic manifold, it is normal for individual abnormalities and it can be replaced for free. However, the customer is not satisfied and requested to ensure that each hydraulic manifold is 100% normal within 12 months. Eugenia became anxious. |
