| Message: | Diego comes from Argentina and specializes in drilling hydraulic machinery. All the hydraulic valves he used are purchased from China and the United States, whether they are hydraulic cartridge valves or hydraulic modular valves. A while ago, he stumbled when purchasing a hydraulic check valve that imitates SUN standard parts from a hydraulic valve manufacturer in Ningbo China. During equipment debugging, it was found that the opening pressure control of the hydraulic check valve in the system was unstable. The original manufacturer of the hydraulic check valve stated that this parameter is based on the SUN standard parts, and to fully match the equipment's operating conditions, it can only be optimized on the original standard parts. However, for the quantity is small, the manufacturer is not willing to do this customization. Diego is embarrassed. |

Is this a real buying request?
