| Message: | Giacomo from Italy, an old customer of AAK, has been purchasing hydraulic cartridge valves smoothly in recent years. At the beginning of last year, he told me privately that he was a little annoyed recently. The hydraulic needle valves he purchased at the beginning of last year was not corrosion-resistant enough, resulting in a claim for their equipment, the four column hydraulic press. The boss has criticized him 3 times. This hydraulic press is used in a chemical plant. After a few months, the system pressure is abnormal. After disassembling the hydraulic needle valve, it was found that the valve body was severely corroded, and the wear was even more serious. The customer requests to replace the hydraulic needle valves immediately and compensate for the delay cost. The original manufacturer is also willing to replace the hydraulic needle valves, but he can only ensure the corrosion resistance for 6 months. Moreover, this batch of hydraulic needle valves is non-standard, and it takes 2 months to reproduce, so Giacomo is not in a good mood because the hydraulic needle valve manufacturer can not solve the problem completely.
