| Message: | Andreus is from a hydraulic equipment company in Chile. He has been in purchasing smoothly for 2 years. At the beginning of the year, their company received an inquiry for a batch of personalized excavators, and customer needed prototypes. The hydraulic cartridge counterbalance valve in the hydraulic system is the key. Their engineer asked Andreus to purchase the standard parts of SUN hydraulic cartridge counterbalance valves, but the parameters did not match, and SUN was unwilling to customize. They had to work with a hydraulic cartridge valve manufacturer who had cooperated with them for 4 years to make samples. But the test run was not smooth. When the load pressure was applied, the opening of the main valve spool of the hydraulic cartridge counterbalance valve would change, affecting the flow and causing the main engine to shake. The hydraulic cartridge counterbalance valve manufacturer had no solution but to give up. Andreus contacted more than 10 other hydraulic cartridge valve manufacturers, but still no result after 1 week. The engineer was impatient, and Andreus was worried. |

Is this a real buying request?
