The hydraulic pressure control valve is high pressure resistant with over 2 million times of service life, AAK won the order back at a high price

China [CN]

Caspar is from Samhydraulik S.p.A. in Italy, mainly responsible for the purchasing of hydraulic valves. In March this year, Caspar requested AAK to sample 10 hydraulic pressure control valves by soonest. This sample order was quoted half a year ago. There must be a reason for him to be so anxious to place an order now. After several rounds of communication, it was learned that Caspar was cheated by the original hydraulic pressure control valve manufacturer.

In the second half of last year, their company developed a new hydraulic power unit, which requires a high-pressure hydraulic pressure control valve, and the durability should reach more than 2 million times. Caspar contacted more than 10 hydraulic pressure control valve manufacturers. Most of them are able to produce the hydraulic pressure control valves with high pressure resistance and durability of more than 2 million times. Only AAK hydraulic valve and other 2 manufacturers have quoted prices. After receiving our quotation, Caspar said that the price of AAK hydraulic pressure control valve was about 20% higher than that of other manufacturers, and then there was no further news. Until today, 6 months later, he was anxious to ask AAK to make samples immediately. 

6 months ago, Caspar selected another hydraulic pressure control valve manufacturer to make samples. 5 weeks later, their new hydraulic power unit was successfully tested and the equipment was expected to be popular. Caspar asked the original hydraulic pressure control valve manufacturer to hurry up to prepare materials, but the manufacturer wanted to raise the price by 40%. Because the valve spool material was hard, the cutting tools needed to be changed constantly, the production cost was increased, and the defective rate was also high. If without a price increase, the manufacturer refuses to produce the order. Caspar felt very helpless.

The boss was very dissatisfied with such a hydraulic pressure control valve manufacturer who raised the price at the last moment, and asked Caspar to find a new manufacturer. Caspar suggested that AAK can make samples. If the original price of AAK hydraulic pressure control valve can be maintained, 20% of the cost will be saved. 1 month later, AAK sent 10 samples of hydraulic valve pressure control valves. 1 week later, Caspar informed that the test was passed and 1,000 samples need to be produced immediately. Caspar also wants to know why AAK hydraulic valve pressure control valve can maintain its original price in the same 6 months, while the other manufacturer needs to increase it by 40%.

Most manufacturers of hydraulic pressure control valves do not pay attention to some details in the processing at the drawing stage, and only know after suffering in the sampling process. This hydraulic pressure control valve has high requirements, especially the reaming of valve spool hole is the key to the finished product. AAK does not need to constantly change the tools, because the ingenious use of cutting fluid in the cutting process can reduce the friction between the tool and the workpiece surface, reduce the chip, and reduce the cutting force and cutting temperature. This is a unique skill. AAK engineers with more than 20 years of production experience strictly control the process, and select the best Castrol cutting fluid in the world. With its high permeability and high adsorption efficiency, combined with the control of our engineers, not only the cost is saved, but also the tool wear is effectively reduced, and the surface quality of the workpiece is also high. 

AAK hydraulic pressure control valve is high-pressure resistant and durable for more than 2 million times. You can also have a small try!
