For instantaneous unloading flow 10000lpm Hydraulic Cartridge Pressure Control Valve, Vadim only found AAK
Vadim is from the Netherlands and has been engaged in procurement in a hydraulic equipment company for 3 years. Some time ago, they encountered a complaint about the hydraulic support they sold. The hydraulic column was bent. This has never happened before. The engineer was surprised. After field analysis, the problem was that the maximum unloading flow of the hydraulic cartridge pressure control valve was too small to realize rapid unloading, which affected the hydraulic column. The original manufacturer of the hydraulic cartridge pressure control valve tried to modify it once, but it was ineffective. Vadim contacted more than 10 cartridge valve manufacturers, but they couldn't make hydraulic cartridge pressure control valves with instantaneous unloading flow of 10000lpm. Vadim was worried.
Vadim browsed AAK website on Google and clicked on the customer case and product introduction of hydraulic cartridge pressure control valves for many times, and left us a message: How to increase the maximum unloading flow of the hydraulic cartridge pressure control valve? My reply: there are many ways to improve it, and we need to make specific analysis. According to the video of bending of hydraulic column and the production drawing of hydraulic cartridge pressure control valve sent by him, after several discussions, AAK engineers have implemented the plan with 90% confidence. Vadim saw the hope and asked for AAK samples. After 50 days, AAK sent 20 samples of hydraulic cartridge pressure control valves.
Last week, Vadim sent an email to express his thanks. It has been more than half a year since the hydraulic cartridge pressure control valves of AAK was installed. The customer has not reported that the hydraulic column is abnormal. AAK engineers improved the internal structure of the original hydraulic cartridge pressure control valve and ingeniously started from 3 points. Vadim said that their engineers also applauded and wanted to find opportunities to learn from each other.
1. The valve spool of the hydraulic cartridge pressure control valve adopts a two-stage stepped cylinder structure. When the high-pressure liquid of the system acts on the large diameter end and the small diameter end of the valve spool at the same time, the area difference between the two ends of the valve spool can greatly reduce the hydraulic pressure borne by the valve spool, so as to achieve the stability of the large flow unloading process.
2. On the cylinder wall in the middle of the front half valve body, 12 unloading holes are uniformly arranged along the circumference, which not only balance the force along the radial direction, but also make the valve spool flexible. At the same time, during the unloading process, it has the largest flow section to achieve super flow unloading, and its maximum instantaneous unloading flow can reach 10000lpm.

Hydraulic Cartridge Pressure Control Valve with 450bar pressure resistance, AAK's service life is twice that of its peers Gallagher is from a hydraulic equipment manufacturing company in Brazil. His purchase has been smooth, but a hydraulic cartridge pressure control valve stumped him. In the second half of last year, they purchased high-pressure hydraulic cartridge pressure control valves for hydraulic power units. About half a year later, a customer complained that the hydraulic cartridge pressure control valve was leaking. According to the feedback from the original hydraulic cartridge pressure control valve manufacturer, the leakage was caused by ultra-high pressure 450bar and it can only be replaced with new one. Gallagher realized that the service life of the hydraulic cartridge pressure control valve produced by the original manufacturer was only 6 months, and the customer required at least 1 year. Gallagher contacted other cartridge valve manufacturers, but none of them was able to guarantee the service life of 1 year for the hydraulic cartridge pressure control valve that is resistant to ultra-high pressure of 450bar. Gallagher was worried. Gallagher found AAK website on B2B, noticed many customer cases related to hydraulic cartridge pressure control valves, and sent an email asking: Can AAK ensure that the hydraulic cartridge pressure control valve withstand ultra-high pressure 450bar working condition, and the service life is more than 1 year? According to the hydraulic system schematic diagram and the original production drawing of the hydraulic cartridge pressure control valve, AAK engineers found that the pressure relief method has a great impact on the valve, will consume the valve life, and is easy to leak. Gallagher asked AAK to make samples. After 35 days, AAK delivered 30 hydraulic cartridge pressure control valves. Last week, Gallagher informed us by email that AAK hydraulic cartridge pressure control valves had been used for 9 months, and no customer complained about leakage. The boss asked to purchase in bulk from AAK to replace the original hydraulic cartridge pressure control valves. I told him that 1 year's life is our basic requirement. He told me that his boss valued the service life of AAK hydraulic cartridge pressure control valve. The other cartridge valve manufacturers can only guarantee a service life about 6 months, while AAK could last more than 1 year. The pressure relief mode of this hydraulic cartridge pressure control valve, is optimized from the following 3 points: 1. The valve body of the hydraulic cartridge pressure control valve is divided into the upper valve body and the lower valve body, and then sealed and fastened with bolts to form the valve body. One end of the valve hole of the upper valve body is used as the pressure fluid inlet, and one end of the valve hole of the lower valve body is used as the pressure fluid outlet.
