The filtration accuracy reaches 10μM hydraulic valve, Dutch customer can’t buy it anywhere else except AAK

Patrick is a hydraulic valve customer in Holland. He has very high requirements for hydraulic parameters. Recently, he needed to purchase a batch of cartridge valves with hydraulic filtration accuracy of 10 microns. He contacted no less than 20 hydraulic valve manufacturers, but no factory dares to accept this order. As the sales season approaches, the hydraulic valve factory has not been approved yet, he became anxious but also a little disheartened, while he was full of confidence in this hydraulic valve order at the beginning.

In recent years, many hydraulic valve manufacturers are used to making hydraulic valve orders from domestic main engine factories, and they don't pay much attention to many foreign trade hydraulic valve orders. The main engine factories have a large demand for hydraulic valves and a low threshold, which has become the "hot spot" of most manufacturers. This leads to a problem that it is difficult for foreign customers to find suitable manufacturers for the orders with high precision requirements.

Patrick contacted AAK through the introduction of his friends and kept asking questions about the parameters of the hydraulic valve. We also deliberately emphasized the control index of the filtration accuracy and replied to the technical questions with strong professionalism, which made him feel that maybe AAK hydraulic valve can meet the requirements of his hydraulic pressure parameters.

The next day, we received Patrick's drawings with detailed information and were requested to make samples. The email repeatedly mentioned the requirement of 10 microns filtration accuracy of hydraulic valve. To dispel his worries, we introduced the use principle of high-precision filter in detail. The pore diameter of filter element in the filter used by AAK can be controlled within 10μm. The hydraulic oil of the test bench is screened by the filter screen before use, and the maximum particle allowed to pass is 10μm.

90% of the conventional hydraulic valve manufacturers generally produce the hydraulic valve per the domestic standard of 25μm. The filtration accuracy can only reach 25 microns, which is too difficult to meet our current filtration standard. Therefore, the service life of these hydraulic valves is about 2 years. According to our production process, AAK hydraulic valve can guarantee 3-4 years, which is almost twice as long as the service life of the hydraulic valve in the same industry.

We sent out the samples in a week. After half a month of testing and comparison, Patrick finally chose to place an order with AAK. It has been more than 2 months since the delivery. Patrick emailed us that the sales volume of this hydraulic valve is very good. It is expected to re-peat the order in the near future and he will also develop a series of hydraulic valve products with the requirements of 10microns filtration precision.

To improve the filtration accuracy and ensure the service life of hydraulic valve products, AAK makes a standard that 90% of the peers can’t reach. Welcome to try an order with AAK.

Previous : AAK is equipped with American honing machine to ensure the accuracy of inner hole of hydraulic valve comparable to Japan equipment factory

Next : The quality of sun series hydraulic valve produced by AAK is comparable to that of sun hydraulic valve produced in the United States
