While 30 Factories Use Traditional Seals Aak Synchronized Swiss Technology 5 Years Ago - China

AAK hydraulic valve blocks adopt MB Series Plug of KVT company in Switzerland, and forms a solid sealing surface after metal extrusion in the way of expansion bite, 100% avoiding oil seepage and oil leakage of hydraulic valve block, which fundamentally solves the problem of high-pressure plugging of hydraulic valve block, and the rated pressure can be as high as 450bar without pollution.

Most hydraulic valve manufacturers fail to seal the hydraulic valve block in place, but AAK has become a long-term cooperative supplier of hydraulic valve block for American customer.

The vast majority of hydraulic valve manufacturers use the traditional sealing method of inner hexagonal (or outer hexagonal) screw plug and sealing combination gasket to process the hydraulic valve block.

The service pressure is basically in the range of 50-300bar, and the operation is simple and easy to disassemble.

The hidden danger is that there are requirements for tightening torque.

If the torque is not reached, it is easy to leak, and if it exceeds, the thread is easy to be damaged, some hydraulic valve manufacturers even apply anaerobic glue on the thread, which is easy to cause particles of anaerobic glue to fall into the hole, resulting in oil pollution or valve jamming of the hydraulic valve.

In addition to the function of hydraulic logic control, some hydraulic valve blocks also need to work for a long time in the environment of high-pressure, high-frequency pressure impact and temperature impact.

Therefore, the sealing process of hydraulic valve blocks is very important.

Declan, an American customer, is a hydraulic friend of Blake.

He recently encountered trouble in purchasing the hydraulic valve block.

The approval sample of the hydraulic valve block provided by the original factory showed that the parameters were completely normal in the first test, and there was slight oil seepage in the second test.

Declan thought it was something wrong with the hydraulic system.

Declan checked and tested the samples for the third time, the hydraulic valve block began to leak oil.

After communicated with the original manufacturer, Declan was advised that this sealing process is common in the industry, he should either accept the hydraulic valve block as is or cancel the order.

Declan consulted more than 30 hydraulic valve manufacturers through B2B, Google and other websites.

Their hydraulic valve blocks all adopt the general sealing process in the industry, and can not guarantee 100% sealing.

After consulting Blake, Blake suggested him contacting AAK and told him that AAK hydraulic valves are not market goods and have some their own R & D processes.

Perhaps AAK does not adopt the general sealing process in the industry for the sealing of hydraulic valve blocks.

According to the hydraulic valve block drawings from Declan, we sent out the hydraulic valve block samples a week later.

2 weeks later, Declan informed us that the parameters of AAK hydraulic valve block were fully up to standard after 3 tests.

AAK has introduced new sealing technology and MB Series products of KVT company in Switzerland as early as 5 years ago, which fundamentally solves the problem of high-pressure sealing of hydraulic valve block.

This technology has low requirements for process hole, is convenient, fast and flexible for installation, and the rated pressure can reach 450bar.

At the same time, it forms a solid sealing surface after intermetallic extrusion by expansion bite, and has no pollution.

The hydraulic valve block with strong stability is the personal bodyguard of high-quality hydraulic valves.

AAK hydraulic valve block, is 100% sealed, free of pollution, easy to operate, you can also have a small try! AAK HYDRAULIC VALVE (138) 2022-01-14
