AAK Hydraulic Screw-in Cartridge Valve Spool Accuracy Testing Tips

Zimraan, from Türkiye, had trouble purchasing hydraulic screw-in cartridge valves from Ningbo China for the first time. In April of this year, they needed to purchase a hydraulic screw-in cartridge valve equivalent to HydraForce FC12-20. With the suggestion of colleagues, he chose a hydraulic screw-in cartridge valve manufacturer in Ningbo and placed the order for 100 pcs directly. They made a spot check in Türkiye and increased the working pressure by 5-10%. They found that a small number of hydraulic screw-in cartridge valves were leaking. The engineer believes that the accuracy of the valve spool component is not up to standard or caused by small scratches, but the original hydraulic screw-in cartridge valve manufacturer believes that it is caused by excessive pressure. Zimraan was helpless and could only inspect the hydraulic screw-in cartridge valves from the original manufacturer one by one.
