Detailed Description

AAK hydraulic pressure control valve has conquered Samuel with 2 million times performance, within 3μm accuracy and 1500H corrosion resistance, with 3 these high differences, winning back the order from Samuel's 5-year old supplier. At the same time, we have also reached a strategic cooperation on hydraulic valves and long-term supply of supporting hydraulic components.

 

Samuel is from a hydraulic equipment company in Italy, and he didn't have much cooperation with AAK in the early stage. At the beginning of the year, they developed a hydraulic cylinder for the solar thermal power generation system in Dubai, and needed to purchase hydraulic pressure control valves. Samuel chose an old supplier who has cooperated for more than 5 years. After 45 days, the hydraulic pressure control valve samples were tested, and it was found that the flow control was unstable. Red rust appeared after more than 500 hours of salt spray test, while Samuel required at least 1,500 hours to adapt to the desert environment of Dubai. The hydraulic pressure control valve manufacturer said that the accuracy is up to standard, and the unstable flow is related to the design. At the same time, the hydraulic pressure control valve adopts the surface treatment of white zinc plating, and the salt spray test should not fail. Samuel was unhappy and had to start looking for a new hydraulic pressure control valve manufacturer.

 

Samuel asked more than 10 manufacturers, but none of them had confidence in the hydraulic control valve with 2 million times of performance used in the desert environment of Dubai. He began to worry at this time, as can be seen from his email to me. He said in his email: I know that AAK has hydraulic flow control valves that are not afraid of high temperature and have been sold to the Middle East, as well as hydraulic counterbalance valves that have not been corroded after a year of sandstorm. I have a hydraulic pressure control valve used in Dubai. No manufacturer is willing to take over. Can AAK make a hydraulic pressure control valve with 2 million times performance used in Dubai? After communication, I learned that the manufacturer he had worked with for 5 years surrendered, and other manufacturers had no intention of accepting orders. I told him that in order to make hydraulic pressure control valve with 2 million times performance used in Dubai, the corrosion resistance of the valve surface must be solved first. Samuel may realize that I have hit the point of the problem, and immediately sent me drawings and other information.

 

Our engineer partially optimized Samuel's original design of hydraulic pressure control valve and told him that for hydraulic pressure control valve with 2 million times performance, within 3μm accuracy and 1,500H corrosion resistance, if the sample of AAK also fails, there is no need to try other hydraulic valve manufacturers in Ningbo, he can just wait for our samples. 45 days later, AAK sent 30 hydraulic pressure control valves. 2 months later, that is, last week, Samuel informed that all the 3 performances of AAK hydraulic pressure control valves had reached the standard, and it was also the only manufacturer that reached the standard. Their team was very happy. Samuel cancelled the PO with the 5 years old supplier and transferred it to AAK. At the same time, we have reached a strategic cooperation on hydraulic valves and long-term supply of supporting hydraulic components.

 

AAK hydraulic pressure control valve can be outstanding with 3 high from peers, which depends on 3 important cornerstones:

 

1. AAK technical team, adhering to innovation and technical transformation, changed the design for 6 times, and finally determined the optimal design of the inlet and outlet of the hydraulic pressure control valve, that is, the optimal hydraulic control ratio. By means of diversion, the relative balance of the pressure on both sides is adjusted to ensure the smooth operation of the equipment.

 

2. AAK hydraulic pressure control valve adopts zinc nickel alloy coating, the nickel content is more than 13%, and the corrosion resistance is increased by more than 10 times. Most manufacturers are unwilling to spend this high cost, and also not able to control this special coating process.

 

3. AAK has produced ODM hydraulic valves for 3 of the world's top 500 for 10 years, and the performance is benchmarked with the international first-line hydraulic valve brands.

 

AAK hydraulic pressure control valve, performance, accuracy, salt spray test, no accident, welcome to have a try!
