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.

Kayden, from AH Garner company in the UK, has successfully purchased hydraulic valve blocks in Ningbo in recent years, and has cooperated with AAK on some high requirements hydraulic valve blocks for many years. He sent an email at the end of last year: I need AAKâ??s help. After communication, we learned that a new hydraulic equipment of their company was complained by customers about oil leakage in about 3 months. After inspection, their after-sales personnel found that when the equipment is switched with high-speed and high-frequency action under high pressure, the small O-ring of the cover plate of the hydraulic valve block is prone to oil leakage. The engineer asked Kayden to find the original supplier to replace the hydraulic valve blocks or cartridge valves. Unfortunately, Kayden purchased the hydraulic valve blocks and threaded cartridge valves from two factories. The manufacturer of the hydraulic valve blocks replied that the thread size accuracy of the cartridge valves did not meet the standard and caused oil leakage, while the cartridge valve manufacturer said that the accuracy of the hydraulic valve blocks did not meet the standard.

The hydraulic valve blocks and cartridge valves have passed the inspection. How can there be a problem as soon as they are assembled on the equipment? Kayden suspected that the design of the hydraulic valve block was flawed, but the engineer thought the design drawing was in line with the principle. The customer didn't receive the solution, and complained to the boss, who asked Kayden to completely solve the oil leakage problem of the hydraulic valve blocks within 30 days. Now Kayden was stumped and didn't have a clue.

I asked Kayden to send us the drawings of the hydraulic valve block and cartridge valve, and system principles. AAK engineers found no problems after analysis. Our engineer asked Kayden to provide the video after the equipment was started up. Combined with the system schematic diagram and equipment fault video, our engineer judged that the position of installing O-ring at the interface of hydraulic valve block and cartridge valve was inappropriate. If the position of the O-ring is lowered, and the cover plate O-ring is completely free of oil, install and fasten the cartridge valve cover plate, and produce the hydraulic valve block and cartridge valve in a same factory, the oil leakage problem of the hydraulic valve block may be solved completely. Kayden seems to have seen the dawn and asked AAK to make samples.

After 25 days, AAK sent out the integrated hydraulic valve block sample. A few days ago, Kayden emailed us that it has been 3 months since the hydraulic valve block was replaced with AAK samples, the equipment works normally without oil leakage. Kayden told me that AH Garner engineer admired AAKâ??s strictness in details. It is so obvious, why didn't he find such an obvious problem?

AAK hydraulic valve has a proprietary valve block anti-rust treatment technology. A special coating with a thickness of 0.02 ~ 0.03 mm is plated on the surface of the hydraulic valve block. The coating has excellent adsorption, is not easy to fall off and has a bright appearance. On this point alone, it has crushed most of its peers. After several email communications, Russian customer resolutely placed an order with AAK.

Due to the limitation of process, most hydraulic valve factories adopt surface painting or conventional electroplating for the anti-rust treatment of the hydraulic valve block surface. Such anti-rust treatment on the surface of the valve block will cause problems in the routine maintenance or repair of the hydraulic valve in the future. It is mainly reflected in that the valve block is easy to be scratched, causing corrosion and increasing system pollution. Besides, falling paint and other sundries are also easy to enter the valve block channel and bring pollutants directly to the system, resulting in secondary pollution of the system and accidents. The trouble is that it is generally difficult to find the problem of rust prevention on the surface of these valve blocks in the short term.

Anatoly, a Russian hydraulic customer, purchased a batch of hydraulic valve blocks in March from a factory. There were no problems in the preliminary test and final inspection. However, he continued to receive feedback from consumers in the last month. After setting up and debugging, the surface of the valve block fell off paint, rusted, and even there is pollution inside the system. According to the statistics of the information received, among the 200 products purchased, there are nearly 100 products in this situation now, and only 100 are still on sale. Anatoly found something wrong and immediately asked to suspend the sales of the remaining products. At the same time, he communicated with suppliers for many times for these inferior products, but the supplier's attitude was very bad and had always been unable to give accurate solutions.

Anatoly used to interact with us on the B2B platform. We didn't know the problems of his valve block until we received his email last month. For these problems, we talked about the current hydraulic market in the reply to his email. In order to save costs, many peers use very conventional anti-rust treatment on the valve blocks. There are mainly two processes:

Directly paint the valve block surface after assembling the components. During component disassembly, replacement and maintenance, it is very easy to damage the paint around the component. At the same time, the fallen paint and other sundries are also easy to enter the valve block duct and cause system pollution

After all the valve blocks are processed, a layer of oxide film plating is carried out. The surface oxide film is relatively thin, which is easy to be scratched, causing corrosion and increasing system pollution.

The intelligently polished hydraulic valve block is 100% burr can not find a second one

Last Wednesday, there was a repeat order from for a hydraulic valve block, which was tested in the second half of last year. required that the repeat order quality should be 100% as same as the hydraulic valve block tested samples last year. comes from a hydraulic equipment company in At the beginning of last year, the paper cutter equipment they sold would stop automatically and was complained by customers. It was found that the hydraulic relief valve was stuck on the site, and the after-sales servicer thought that there was a problem with the hydraulic relief valve. After the original hydraulic valve block manufacturer disassembled it, it was found that there were debris at the moving part of the valve spool. At the same time, foreign matters were also found in the hydraulic oil, so it was known that it was caused by the incomplete burr cleaning of the hydraulic valve block.

The original hydraulic valve block manufacturer also does not deny it. The burr cleaning of the inner cavity of the oil channel, the cross hole and the blind hole of this hydraulic valve block was indeed less than 100%. As long as the hydraulic oil can be replaced every 3 months, the problem can be solved. was very speechless and had to find a new hydraulic valve block manufacturer, and deliberately required 100% burr free. She contacted more than 10 hydraulic valve block manufacturers, they either gave no reply or could only have a try, but didn't have time to test, and began to worry.

noticed the introduction of 100% burr free hydraulic valve block in on Google, so she directly sent us an email. I told her, according to your hydraulic valve block drawing, there are many inner cavities and cross holes in the oil duct, especially the burr cleaning at the blind hole is a difficult problem. The traditional abrasive flow deburring method to remove this hydraulic valve block has hidden dangers. suffered from it 5 years ago, and it was not until we used the new deburring technology that we dared to ensure 100% burr free asked us to make samples as soon as possible. A month later, sent 5 hydraulic valve blocks.

6 months later, us that the paper cutter installed with hydraulic valve block has been working normally. I told her that adopted an intelligent grinding processing system to replace the traditional abrasive flow process. If this hydraulic valve block is deburred with abrasive flow, and the blind hole is easy to form a dead corner. The intelligent grinding and processing system can realize automatic solution. In the grinding process of the hydraulic valve block, with continuous power support and stability, the main shaft of the equipment can swing 360 , which can realize the grinding of any angle and any inclined plane.
