Message: | For hydraulic pilot operated relief valve with machining accuracy below 0.5μm, and test accuracy 0.05% FSO BFSL, Renzo found AAK only. Renzo comes from an Italian hydraulic equipment company and has been engaged in hydraulic cartridge valve procurement for many years. At the beginning of last year, they developed a high-end hydraulic injection molding machine, which requires a hydraulic pilot operated relief valve. Renzo chose an old supplier to make samples, and the machine test run was also successful. The equipment began to be put into production, but 3 months after sales, a customer complained that the positioning of the injection molding machine was inaccurate, resulting in product deformation. After troubleshooting, it was found that the flow of the hydraulic pilot operated relief valve was unstable. |
