Although the price of AAK Hydraulic Directional Control Valve is 20% higher, Aet

Aether is a customer of AAK in Greece and has been purchasing hydraulic cartridge valves from AAK for 3 years. At the beginning of last year, he asked me about the sealing ring options available at AAK and I felt a bit strange. I didn't provide a direct answer and take an example, if I simply asked the doctor about the medication options, the doctor would definitely need to know the patient's symptoms or cause. After further communication, it was learned that they had encountered difficulties on a hydraulic directional control valve. Due to rapid wear of the sealing ring of the hydraulic directional control valve, there was leakage and the equipment was abnormal. The original manufacturer blamed the hydraulic directional control valve for being used too frequently, resulting in wear and tear on the sealing ring, which can only be replaced with new ones. Aether cannot accept replacing the sealing ring within only 3 months.

Aether's demand is to address the issue of hydraulic directional control valve leakage without the need for frequent replacement of sealing rings. When I received the sample of the hydraulic directional control valve from the original manufacturer, I found that Aether had sent me an inquiry for this model before. I also understood why he only asked about the sealing ring at first. I told Aether that the original sealing method is a metal conical hard seal, which is difficult to ensure leakage if used frequently. Optimizing the original sealing structure can achieve no leakage for more than 1 year, but the production cost of hydraulic directional control valves would be increased. Aether was also candid and told me frankly that when inquiring, it was because AAK's price was more than 20% higher another hydraulic cartridge valve manufacturer that he chose. 60 days later, AAK sent out 50 samples of hydraulic directional control valves to address Aether's urgent needs first.

Last week, Aether informed us that AAK hydraulic directional control valve has been installed on the equipment for almost a year and there are no leaks. Their customer is very satisfied, and his boss also suggested that he make AAK their preferred supplier of hydraulic directional control valves. The production cost of AAK hydraulic directional control valve is high, which is because these 3 aspects require more money than peers. AAK hydraulic directional control valve adopts a dovetail groove sealing ring through the valve spool pressure plate, which is pressed against the step hole of the valve body along with the valve spool, playing a sealing role. Oil cannot return from the inlet chamber to the return chamber, achieving zero leakage.
