| Message: | Nantan, from Greece, is an old friend of mine. He has cooperated with AAK Hydraulic Valve for 5 years. Last month, I received a sample of hydraulic cartridge relief valve from him. He needed me to optimize it. In the first half of this year, their customer's die casting machine prototype needed to customize the hydraulic cartridge relief valve. Due to tight time frame, Nantan made samples from a local hydraulic cartridge valve manufacturer who had cooperated with them. The equipment commissioning was not smooth, and there was vibration and noise when the hydraulic cartridge relief valve was opened under the condition of large flow and pressure relief. The manufacturer advised that the problem was caused by the internal structure of the hydraulic cartridge relief valve, but he was unable to optimize it. Their engineers complained that the hydraulic cartridge relief valve purchased by Nantan was abnormal, which embarrassed Nantan. |

Is this a real buying request?
