Shirley comes from a hydraulic equipment company in the United States, who is an old employee of the company. She rarely fails in purchasing, and her cooperation with AAK is tepid. It was not until the cartridge hydraulic flow control valves purchased last year failed that she learned that AAK Hydraulic Valve was different from other hydraulic cartridge valve manufacturers, and now she is sending us more and more inquiries.

 

At the beginning of the year before last, Shirley’s company sold the hydraulic power unit for metal extrusion equipment. Less than half a year, customers complained that the pressure of the power unit was abnormal, and even went on strike. During after sales service, it was found that the leakage was caused by the serious wear of the hydraulic flow control valve sleeve, resulting in abnormal equipment pressure. The original hydraulic flow control valve manufacturer replied that under the high-pressure working condition of 450bar and high-frequency use, it is unavoidable for the hydraulic flow control valve sleeve to be worn and the only solution is to replace with new one for free, but 5 months later, the same problem occurred again. The customer was not satisfied and complained directly to the boss. The boss was surprised that an old hand like Shirley would stumble. After investigation, it was found that this hydraulic valve manufacturer who had cooperated for 5 years ignored the details of high pressure and high frequency.

 

The boss asked her to change the manufacturer and replace those severely worn hydraulic flow control valves as soon as possible. Shirley thought of AAK, because at the beginning of the inquiry, AAK mentioned that this hydraulic flow control valve had special working conditions, if the material selection was not proper, it would be impossible to use it for 1 year or more. After learning of Shirley's procurement dilemma, AAK urgently produced 50 hydraulic flow control valves within 1 month for them to replace the current ones. 6 months after the trial order was delivered, Shirley informed us by email that the equipment installed with AAK hydraulic flow control valve was working well without any abnormalities, and I said there would be no abnormalities even in 1 year. Shirley admired the confidence of AAK Hydraulic Valve in quality, and ordered another 300 hydraulic flow control valves.

 

Under the high-pressure condition of 450bar, to get the hydraulic flow control valve used in high frequency a service life of more than 1 year or 2million times, AAK Hydraulic Valve uses 3 advantages to exceed peers.

 

1. The valve sleeve of AAK hydraulic flow control valve adopts 18Cr2Ni4WA high-strength alloy carburized steel. During heat treatment, carburize at 900~920 , temper at 600~650 , and then cryogenic treatment. In this way, the hardness of the valve sleeve is more than HRC65, and it is not afraid under the high pressure condition of 450bar. The difficulty of this material lies in heat treatment, while most of hydraulic valve manufacturers can not control this technology.

 

2. AAK has independently developed hydraulic valve durability test equipment, and carries out fatigue test on materials in combination with NFPA/T2.6.1 standards to ensure that each hydraulic flow control valve is qualified before shipment.

 

3. For the hydraulic cartridge valve with a service life of 2 million times under 450bar high pressure, AAK has customers who used them in aviation.  

 

AAK hydraulic flow control valve, durable under high pressure and high frequency use, you can also have a small try!
