| Message: | Quentin is from Italy. He is a new purchaser of a company which has cooperated with AAK for 4 years. He is very aggressive, but the first purchase of hydraulic relief valves overturned. At the beginning of this year, a batch of excavators of their company needed hydraulic relief valves, which were standard parts of HydraForce. Quentin asked more than 10 hydraulic cartridge valve manufacturers, and chose one manufacturer that is 60% cheaper than HydraForce to place an order. Six months later, trouble began. A customer complained that the oil pipe of the excavator burst. The engineer realized that it was not just the problem of replacing the oil pipe. It was found through inspection that the hydraulic relief valve was sluggish during operation, resulting in the instantaneous formation of peak pressure in the system, which caused the oil pipe to burst. The inner wall of the valve hole of these hydraulic relief valves was worn. However, the manufacturer of the original hydraulic relief valves said that it was caused by the unclean hydraulic oil, which had nothing to do with them. Quentin was afraid to take responsibility and dared not report to his boss. |
