The Rated Flow Setting of AAK Hydraulic Valve is Unique and Distinctive

Bryson is a hydraulic customer from the UK. Recently, a batch of hydraulic cartridge valves he temporarily purchased were in trouble. Because the parameters from customer were not complete, he used the same model product recommended by the hydraulic valve manufacturer instead. During testing, the flow parameters were not equal. The rated flow of the hydraulic cartridge valve was smaller than the working flow and could not be used normally, which wasted more than 10 days and the delivery time was urgent. He contacted with more than 10 hydraulic valve manufacturers. For hydraulic cartridge valves of the same model, their rated flow setting is either smaller than the working flow or close to the working flow of the system. Bryson was very distressed that no hydraulic cartridge valve has a rated flow setting greater than the working flow.

Bryson found AAK HYDRAULIC VALVE. From AAK website, he felt that AAK HYDRAULIC VALVE was a little different from other hydraulic valve manufacturers. With a try attitude, Bryson actively contacted us and sent us the product picture and product model of this hydraulic cartridge valve. He just emphasized that the rated flow must be greater than the working flow and asked us to recommend the hydraulic cartridge valve of the same model, there was no any parameter information. After careful comparison, AAK engineers sent pictures and drawings of a hydraulic cartridge valve of the same model. Bryson asked us to send the hydraulic cartridge valve samples as soon as possible.

On the 3rd day after receiving the hydraulic cartridge valve sample, Bryson emailed to inform that the rated flow of AAK hydraulic cartridge valve can really meet the normal operation of their current hydraulic system. Bryson expressed his curiosity that the hydraulic cartridge valve model recommended by AAK is consistent with that recommended by other manufacturers. How can there be such a big difference in the rated flow setting?

For the selection of flow specifications of hydraulic valves, the settings of each factory are different. If the rated flow of the valve is close to the working flow of the system, this situation is the most economical and cost-effective, and it is also the first choice of nearly 90% of hydraulic valve manufacturers. But there may be a problem, once the working flow in the hydraulic system exceeds the rated flow, it will cause hydraulic clamping and affect the hydraulic power. It will also have an adverse impact on the hydraulic system of the valve. To be safe, when all cartridge valves are produced, AAK will give priority to the maximum flow that may pass through the circuit where the hydraulic valve is located, and the setting of rated flow is greater than the maximum flow of operation, so as to ensure the normal operation of whole system, which is also the reason why most customers prefer AAK.

After knowing this information, Bryson is more convinced that AAK HYDRAULIC VALVE is different from other hydraulic valve manufacturers. It has been more than 3 months since we shipped the last goods to Bryson. Today, 200 hydraulic cartridge valves are re-ordered. Bryson told me that since AAK hydraulic cartridge valve was used, there was no hydraulic clamping problem in the hydraulic system.
