The original manufacturer cannot handle the SV12-22 hydraulic solenoid cartridge valve with hardness HRC70, but AAK solved it using the

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.

Abel found AAK. After communication, it was learned that he was in trouble while purchasing the SV12-22 hydraulic solenoid cartridge valve. I told him that the brake oil medium is used in the SV12-22 hydraulic solenoid cartridge valve, even if HydraForce original valve will also have potential failures, and it is necessary to improve the hardness of the material and perform anti-corrosion treatment. Especially in the precision machining process, most hydraulic cartridge valve manufacturers cannot control the stability of accuracy very well. I suggested making samples for Abel directly. After 45 days, AAK sent 30 pcs of improved SV12-22 hydraulic solenoid cartridge valve samples to resolve Abel's customer complaint first.

3 months later, Abel informed us via email that no leakage was found on the AAK SV12-22 hydraulic solenoid cartridge valve samples, and they wanted to re-peat the order for 300 pcs. I think that the accuracy of AAK SV12-22 hydraulic solenoid cartridge valve has received his recognition and reorder.

The improved SV12-22 hydraulic solenoid cartridge valve adopts the American SUNNEN honing machine in the valve cage precision machining process, with its SAC size automatic control system. It does not automatically stop until the honing reaches the accuracy set by the system. The upgraded filtration system eliminates impurities in honing oil. Especially for diamond honing stones, processing materials with HRC70 or higher is a perfect match, not only stable but also efficient. Our technicians perform the following operations: first, set the correct machining program on the computer system of the equipment, and then install the rough machined valve cage into the equipment. After starting the program, the equipment automatically completes honing. With the escort of this equipment, the precision of the processed hydraulic cartridge valve cage is stable within 2μm, the roundness can reach 1.5μm. The roughness can reach Ra0.1. But most hydraulic cartridge valve manufacturers do not have such high-end honing equipment, and there are few equipped with diamond honing stones, which is the key to the inability to process high hardness valve cages.

AAK SV12-22 hydraulic solenoid cartridge valve is processed with 3 advantages of equipment, and 2 methods of operation. You can give it a try!
