Renzo is from Italy. As an old purchaser of the company, he has been doing very well before. The hydraulic directional control valves purchased at the beginning of last year distressed him. One of their high-pressure hydraulic supports had leakage due to corrosion of the hydraulic directional control valves 6 months after sales, resulting in instability of the support. The original hydraulic directional control valve manufacturer thinks that the corrosion is caused by the extreme working environment and cannot be completely improved. Renzo realized that trouble was coming and began to contact the new hydraulic directional control valve manufacturers. However, after 2 weeks, no hydraulic valve manufacturer guaranteed that it would not corrode for 1 year in an environment with high sulfur... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVE

At the beginning of this year, Samuel asked by email about the production time of 1,000 hydraulic needle valves, He specially emphasized that the technical parameters of the hydraulic needle valves need to be the same as those samples made before, especially the valve hole accuracy must be 100% within 1μm or less. Samuel has been cooperating with AAK for 3 years. It is the first time that he deliberately emphasized as such in email. After communication, I learned that the hydraulic needle valves that AAK made samples for last time was 20% higher than that of other hydraulic valve manufacturers, so he placed the order with another manufacturer. However, now this batch of hydraulic needle valves have been complained by customers that the hydraulic winch is stuck. The root cause is that the... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

At the beginning of the year, Torsten, an old customer of AAK, was in urgent need of 200 hydraulic directional control valves and specially emphasized delivery within 30 days. I felt Torsten was in big trouble. Torsten from the Netherlands has cooperated with AAK for 5 years. In case of trouble, basically, he consults me first. It turned out that their hydraulic pipe jacking machine was complained by customers half a year after sales. During construction, the equipment suddenly dropped. The problem was that the hydraulic directional control valve leaked, causing the hydraulic system not to maintain pressure. The manufacturer of the original hydraulic pressure directional control valves was willing to replace the faulty hydraulic directional control valves for free. However, there were more...

AAK HYDRAULIC VALVES

Caleb from Mexico, needs to purchase hydraulic relief valves suitable for seawater. Several local hydraulic relief valve suppliers dare not quote because of the uncertain working environment of seawater medium. Caleb had to try to find overseas manufacturers of the hydraulic relief valves. Perhaps because there is no overseas procurement base, there are few hydraulic valve manufacturers willing to cooperate, which makes Caleb helpless. When he almost gave up, his friend Ron learned his situation and suggested him to contact AAK Hydraulic Valve. Perhaps AAK can bring him an unexpected surprise.

After receiving an email from our old customer Ron, I learned about the dilemma that Caleb encountered on the purchase of the hydraulic relief valves. According to the hydraulic relief... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Lawrence is from Italy. He has been purchasing hydraulic components for quite a long time, and it is relatively smooth. In the second half of last year, when purchasing hydraulic pressure control valves with 1μm precision valve spool, he encountered problem. Their company has developed a hydraulic shear with double cylinder steel structure. The adjustment of the blade clearance of the hydraulic system depends on the hydraulic pressure control valves, especially the precision of the valve spool should be controlled within 1μm. A hydraulic valve manufacturer that has cooperated for 5 years made the samples for this hydraulic pressure control valve, but the scissors clearance was not sensitive. The engineer found that the valve spool of hydraulic pressure control valve moved abnormally. The... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Logan, a British customer, checked with 10 hydraulic valve manufacturers that he often contacted, none of them can make a hydraulic relief valve with high pressure resistance of 450Bar. Only AAK solved the problem of high pressure resistance with 68HRC material and ensured the performance of 2 million times.

According to the requirements of the engineer, Logan defines the material hardness of the hydraulic relief valve as above 68HRC, which is 10% higher than that of the conventional hydraulic relief valves. After a round of consultation, 8 hydraulic valve manufacturers gave up, and the other 2 old hydraulic relief valve suppliers tried to make samples. 2 weeks later, the hardness of the samples of the 2 hydraulic relief valve suppliers remained at 63-65HRC, which was their...

AAK HYDRAULIC VALVES

Yesterday, I saw a report in the New York Times: "China's economic slowdown has brought difficulties to the United States and the world.". It seems that now it's China's turn to catch a cold, and the world will sneeze.

During this period, the domestic financial and economic columns have become more and more confused. There are both pessimistic and optimistic views on China's economy, but it seems that most of the big news are always pessimistic. At present, there are indeed difficulties, but China has its own special 3 trumps: autonomy and independence, a complete industrial and technological chain, and the world's largest economy.

I don't like pessimistic views and remarks very much. Foreign media have been criticizing China for decades, and some domestic elites... Читать дальше (Содержит видео)

For the hydraulic check valve with the length diameter ratio of 25:1, Andrew contacted with more than 20 hydraulic check valve manufacturers online and offline in 1 week, but none of them was willing to offer. The boss was very dissatisfied and Andrew was very headache.

Andrew from Spain left a message on AAK Hydraulic Valve website some time ago: can you make samples for a hydraulic check valve with a length diameter ratio of 25:1? After communication, we learned about his current purchasing situation. Because he saw on B2B that AAK published an article on the length diameter ratio of a hydraulic relief valve, then he contacted us with a try attitude. According to Andrew's drawings, it is a long and thin shaft hydraulic check valve with very complex structure. No wonder no... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVE

Torsten is from the Netherlands. As an old purchaser, he is very handy in the hydraulic industry. Unexpectedly, he fell on a hydraulic valve block with 24 deep holes and large holes. In the second half of last year, his company developed a large-scale hydraulic windlass for ships. The hydraulic valve block used was sampled from a hydraulic valve block manufacturer in the Netherlands, but the machine running test was not smooth. After the equipment has been operated for 8 hours, there is leakage at the installation hole of the hydraulic valve block. After eliminating the suspected quality of the hydraulic cartridge valves, the engineer inspected the installation hole of the hydraulic valve block and found that the center position of the hole was offset.

The original... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Last week, the German customer Thorsten sent an order for 1,200 hydraulic counterbalance valves, and said that only AAK and SUN hydraulic counterbalance valves passed 1 million durability tests among the 6 hydraulic valve manufacturers making the samples. However, the price of AAK was 30% lower than that of SUN, and the delivery time was faster.

In May this year, Thorsten's company received an order for a batch of special hydraulic winches. The customer requested that the equipment be guaranteed for at least 1 year of service life. The engineer required that the durability test of the hydraulic counterbalance valve to be purchased by Thorsten must reach more than 1 million times. Thorsten found a local hydraulic counterbalance valve manufacturer to carry out the test. After... Читать дальше (Содержит видео)
