A Hundred Non Standard Hydraulic Cartridge Valves Helped Aak Supply 7 World Top 500 Enterprises - China

price: 100.00 Dollar US$

Today, the American customer April has placed another new order for hydraulic cartridge valves.

Coincidentally, this PO is for 100 non-standard customized hydraulic cartridge valves that AAK has cooperated with them for 10 years.

April is the first customer of AAK Hydraulic Valve to enter the overseas market, and also the first foreign trade order of AAK Hydraulic Valve 3 years after its establishment.

Up to now, AAK hydraulic cartridge valves have been supplied to 7 world top 500 enterprises.

AAK hydraulic cartridge valves adhere to 3 points, adhere to the manufacturing quality of hydraulic cartridge valves, pay attention to research and development, and focus on innovation.

In particular, the high-precision and high-performance hydraulic cartridge valve samples have been defeated repeatedly, but we never give up until success.

April's first inquiry is for hydraulic cartridge valves used in the military industry, with an accuracy of 0.8μm or less, the durability of more than 1 million times, and the opening and closing performance of 1 second.

Our engineer was a little timid when he saw these requirements.

I told him that if the development was successful, all the credit would go to him.

If it failed, I would pay for it.

2 months later, the samples of AAK hydraulic cartridge valve was sent out.

2 weeks later, April reported that the opening and closing performance of AAK hydraulic cartridge valves reached the standard, but the accuracy and durability tests failed.

This indicates that the material selection is incorrect and the process is correct.

I told April that AAK was confident that the samples would be successful.

3 months later, the test of AAK hydraulic cartridge valves still failed, and the durability was barely 800, 000 times.

I encouraged the engineer to continue the test.

5 months later, the AAK hydraulic cartridge valve was approved by April.

At the same time, the never say die spirit of AAK also makes April admire, because AAK is the only manufacturer of hydraulic cartridge valves that insists on testing samples in 1 year and does not give up.

AAK hydraulic cartridge valves, in the face of failure, the wealth gained is that after every failure, there is an increase in technology accumulation, of which the most critical is 3 points: 1 - Equipment updating is not stopped, and fixture innovation should be synchronized.

5 years ago, the precision honing machine imported from the United States was introduced.

The accuracy of valve holes processed by other hydraulic cartridge valve manufacturers is 0.8μm--1.0μm, while with AAK synchronous innovation fixture, the valve hole accuracy can be within 0.6μm--0.8μm, which is 20% higher.

2 - Material types: AAK material warehouse has 12 kinds of special steels, such as 3Cr3Mo3W2V hot work die steel, 20CrNi2MoV high-permeability carbon bearing steel imported from Germany, Hastelloy alloy steel imported from the United States etc.

At the same time, there are 8 kinds of sealing ring materials.

At any time, we can meet the requirements of customers with high quality hydraulic cartridge valves.

3 - Technology and process upgrading: AAK has senior engineer from HAWE, and technical teams with an average of more than 15 years of industry experience, adhere to the manufacturing quality of hydraulic cartridge valves, pay attention to research and development, and focus on innovation.

AAK hydraulic cartridge valves are supplied to 7 world top 500 enterprises.
