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.

 

According to the feedback of the original hydraulic relief valve manufacturer, the accuracy of this hydraulic pilot operated relief valve requires to be within 1μm, it is difficult to guarantee this accuracy on each valve, and it can be replaced for free. However, there are more and more similar complaints later, and the second batch of injection molding machines will also be put into production. The boss was very angry and asked Renzo to solve it at one time and find a hydraulic relief valve manufacturer with stable quality. Renzo contacted more than 10 hydraulic cartridge valve manufacturers, but most of them were not able to achieve the accuracy within 1μm, Renzo was very anxious.

 

Renzo began to source new hydraulic relief valve manufacturers online, and found AAK Hydraulic Valves on Google. He requested that the machining accuracy of each hydraulic pilot operated relief valve needs to be within 1μm. I replied to him that unless accidental, the machining accuracy of AAK hydraulic pilot operated relief valve can be within 0.5μm, Renzo was relieved. One month later, AAK delivered the first batch of quantity. Three months later, Renzo emailed that with AAK hydraulic pilot operated relief valves, there was no customer complaint that the positioning of the injection molding machine was inaccurate during operation, and the processing accuracy was all within 0.5μm. The next day, his placed the order for the second batch of hydraulic pilot operated relief valves.

 

AAK can produce the hydraulic pilot operated relief valves that can be 100% qualified, and the machining accuracy is within 0.5μm, it is mainly because that we control both the processing and testing strictly, and the domestic hydraulic cartridge valve manufacturers generally cannot control the details of the process.

 

AAK uses American Hardinge ultra-high precision machine tool to produce this hydraulic pilot operated relief valve, and the machining accuracy can reach 0.1-0.5μm, ensuring that the valve hole accuracy of each hydraulic relief valve is consistent. After processing, each hydraulic relief valve is tested. The pressure test bench is equipped with BD SENSORS pressure sensor imported from Germany, which has strong overpressure resistance. The range can reach 0 to 2200bar, and the test accuracy is 0.05% FSO BFSL. It is equipped with pressure measuring equipment with digital display and power-saving output. During the test, technicians can clearly see the test data, which is easy to operate, easy to track, and no oversight.

 

AAK hydraulic pilot operated relief valve, each product makes you feel at ease, welcome to have a small try!
