AAK Has Mass Produced the Hydraulic Cartridge Valves with Filtration Accuracy Up to 10 Microns 3 Years Ago

Nearly 90% of the hydraulic cartridge valve manufacturers in Ningbo can not achieve the filtration accuracy as high as 10 Microns. But AAK is one of the less than 10% hydraulic cartridge valve manufacturers with a filtering accuracy up to 10 Microns.

 

Dylan came to AAK HYDRAULIC VALVE with a very special two position 2 way hydraulic cartridge valve. I knew he should have encountered a problem. For this special hydraulic cartridge valve, the filtration accuracy of 10 Microns was the minimum requirement. Dylan consulted the existing cooperated hydraulic cartridge valve manufacturers, but none of them could meet the requirement. Most hydraulic cartridge valve manufacturers said that the filtering accuracy of 25 Microns is 100% no problem. Only 1 hydraulic cartridge valve manufacturer gave feedback and was 70% sure that the filtering accuracy could reach 10 Microns.

 

Dylan directly asked me, is it really difficult for these hydraulic cartridge valve manufacturers in Ningbo to achieve the filtering accuracy of 10 microns? How can so many hydraulic cartridge valve manufacturers have said that they can only achieve the filtering accuracy of 25 Microns? I could understand his helplessness and confusion.

 

This is because that the conventional hydraulic cartridge valve manufacturers produce hydraulic valves according to domestic hydraulic standards in China. Not only 1 or 2, but nearly 90% of hydraulic cartridge valve manufacturers, are only able to get the filter element aperture reaches 25μm. We AAK HYDRAULIC VALVE also used conventional filters at the beginning, and the filtration accuracy was also based on domestic standards. 3 years ago, a German hydraulic valve customer requested the accuracy requirement of 10 Microns, which was not only a stimulus but also a challenge for us. After more than 2 months of adjusting, we improved the process on the small sample, and adjusted the equipment parameters until it was configured to a high-precision filter and cooperated with AAK special hydraulic oil, so that the filtration accuracy of particles in the hydraulic oil could be controlled to 10μm. 1 year later, some hydraulic cartridge valve manufacturers learned that AAK had upgraded with high-precision filters and followed suit. However, due to technical constraints, many hydraulic cartridge valve manufacturers still failed to meet the standard. Under the same working conditions, if the hydraulic cartridge valves from these hydraulic cartridge valve manufacturers have a service life of 2 years, the service life of AAK hydraulic cartridge valves can be extended to 3-4 years.

 

Dylan was surprised that we had mass produced hydraulic cartridge valves with filtration accuracy up to 10 Microns 3 years ago, but only 1 of his current hydraulic cartridge valve manufacturers could do it, and with only 70% sure. Dylan took out the drawings and asked us to send samples of this special hydraulic cartridge valve within 20 days.

 

AAK HYDRAULIC VALVE, always has high requirements on precision. If you need to find a high-precision hydraulic cartridge valve manufacturer, do not hesitate to contact us.
