William comes from a Canadian hydraulic equipment company and has purchased hydraulic valve blocks in Ningbo for several years. AAK also supplies several difficult hydraulic valve blocks to their company. Although the quantity is not big, AAK service makes William very satisfied. In the second half of last year, William emailed an inquiry for a big quantity of order for hydraulic valve blocks. William said that the quotation was 40% higher than that of other hydraulic valve block manufacturers. I'm not surprised at all that he advised that the price of AAK hydraulic valve block is 40% higher.

 

According to the hydraulic valve block drawing provided by William, AAK engineers found that according to the working condition requirements of the hydraulic valve block and the minimum wall thickness between two adjacent parallel holes (including installation threaded holes) in the middle of the valve block designed on the hydraulic valve block drawing is less than 4mm, the 6061-T6 Aluminum material marked in the drawing is not suitable, because this wall thickness can not bear the pressure of 350bar at all. During the operation of the equipment, the hydraulic valve block is likely to be broken down because it cannot withstand high pressure, that is, the materials used for the hydraulic valve block must be changed, rather than blindly follow the original hydraulic valve block drawing. AAK uses 7075-T6 aviation aluminum, which is the root cause of 40% higher price. A week later, William replied that he also sent the inquiry to the old hydraulic valve block supplier and more than 10 other hydraulic valve block manufacturers, but none of them suggested change the aluminum materials. He wondered whether AAK deliberately changed the materials for more profits. This large order of hydraulic valve blocks had been placed with the original supplier. Then I replied with a few words: good luck.

 

Two months later, William sent an email saying that he regretted that he had not followed AAK suggestion at the beginning. The hydraulic valve block sample from old supplier was debugged 3 days after the equipment was installed. The manufacturer of the hydraulic valve blocks said that the sample was completely in accordance with the drawing and the development cost could not be refunded. The equipment commissioning time was wasted. The boss was very unhappy and asked William to try AAK samples even if the price was 40% higher, and asked to send the hydraulic valve block samples as soon as possible. AAK uses 7075-T6 aviation aluminum to make samples by soonest. After 30 days, AAK sent 2 samples of hydraulic valve blocks.

 

Last Monday, when I opened the mailbox, I saw the unread email of hydraulic valve blocks from William. I knew that AAK hydraulic valve blocks passed the test of equipment commissioning. After opening, as expected, he placed a large order of 800 hydraulic valve blocks at one time. He also felt sorry to mistake AAK professional suggestion for deception.

 

The 6061-T6 material on his hydraulic valve block drawing is only suitable for hydraulic valve blocks with a pressure below 220bar and a wall thickness of more than 5mm. Compared with 6061-T6, 7075-T6 aviation aluminum material has high strength, high hardness, more precision, good toughness, can be pressed or impacted for a long time, is not easy to deform, and has excellent wear resistance and fatigue resistance. It is the aluminum alloy with the highest strength at present.

 

AAK hydraulic valve block is highly professional and cost-effective. You can also have a small try!
