Message: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.
Jul 02 2022 Some peers are imitating AAK hydraulic valve. What do you think?6
Jul 01 2022 Engineers define the hydraulic manifold design from 5 perspectives, making AAK have no peers15
Jun 08 2022 The hydraulic flow control valve is benchmarked with Brevini, and the Italian customer can't refuse the 3 great benefits of AAK22
Jun 07 2022 AAK hydraulic relief valve was 17% expensive, but no cavitation. The Canadian boss purchased 2,000pcs after 2 years16
Jun 06 2022 Hydraulic manifolds of 450MPa pressure resistance and ultra light weight , AAK samples can be used in aviation at one time21
Jun 05 2022 How do you understand AAK mindfulness of be a man of credit and integrity to make hydraulic valves?20
Jun 04 2022 Customer who are greedy for cheap hydraulic valves got back to AAK after suffering heavy losses22
Jun 03 2022 Only AAK was able to produce the hydraulic manifold blocks, and its technology is not inferior to American and Japanese counterparts35
Jun 02 2022 AAK processed the hydraulic valve blocks with compound cutting tools, the quality caught up with Germany, and the delivery was 30 days faster23
Jun 01 2022 Hydraulic manifold blocks purchased separately had oil leakage, and AAK take over to produce the whole and promise no repair within 1 year19
