Message: | Abel from Dubai, who has been purchasing hydraulic cartridge valves in China for 3 years, has been running smoothly, but he encountered trouble with a hydraulic solenoid cartridge valve that is benchmarking against HydraForce SV12-22. At the beginning of this year, their hydraulic manifold used in logistics vehicles required the SV12-22 hydraulic solenoid cartridge valve. Abel purchased 100 pcs of hydraulic cartridge valves from the original hydraulic cartridge valve supplier in China. 1 month later, their customer complained about the leakage of the hydraulic cartridge valve, and the engineer found that the valve cage of the hydraulic cartridge valve was significantly worn and the valve spool was corroded. The original manufacturer shifted the blame and the brake oil medium used did not meet the standard. Alternatively, materials with a hardness of HRC70 or higher may be used, but the machining accuracy cannot be guaranteed. Abel was helpless and anxious. |
