Today's weather is fine and I'm in a good mood, too. It took us 6 months to finally send the samples of the hydraulic counterbalance valves used in the sandstorm to Leonard. Their company has operated hydraulic equipment in Italy for more than 30 years. Leonard has been successful in purchasing hydraulic valves. AAK is their old supplier of hydraulic valves, but he has not purchased hydraulic balance valves from AAK yet. In the past, I asked why there was no inquiry or sampling of hydraulic counterbalance valves. He advised that their hydraulic counterbalance valves were purchased from another supplier who had cooperated for many years.

 

At the beginning of last year, Leonard sent an inquiry for the hydraulic counterbalance valves. At that time, I was a little surprised. I estimated that he had trouble purchasing hydraulic counterbalance valves from the original manufacturer. After communication, it was learned that their company had a batch of hydraulic equipment sold to the Middle East in previous years, and the hydraulic counterbalance valves used had to be replaced almost every 6 months. The customer was not very satisfied with this high-frequency after-sales service. The original manufacturer said that the hydraulic counterbalance valves used in other places do not need to be replaced for 1 or 2 years. There is often haze or sandstorm weather in the desert areas of the Middle East, and the solid particles will virtually cause corrosion to the exposed surface of the hydraulic counterbalance valves, resulting in a high replacement frequency of the hydraulic counterbalance valves, and there is no good way to solve it at present.

 

Leonard contacted AAK to improve their after-sales service. Try AAK hydraulic counterbalance valves to see if they can be used for more than 6 months in a sandstorm environment. According to the hydraulic counterbalance valve drawings from Leonard, the parameter requirements are of medium grade. The core is to select the stainless steel with the best corrosion resistance as the external parts of the hydraulic counterbalance valves. I suggest Leonard ask his customer to send the particles in the worst weather to AAK, analyze the PH of the environment, and then increase the PH by 30% to test the service life of different steels.

 

Three months later, Leonard asked about the progress of the hydraulic counterbalance valve samples and joked that if AAK development is successful this time, all their future hydraulic counterbalance valves will be purchased from AAK. Another three months later, a special steel produced by ArcelorMittal group from Luxembourg was successfully tested by AAK technical team. Using this special steel as the external part of the hydraulic counterbalance valves can ensure corrosion resistance for at least 1 year. It took us 6 months to finally send samples of the hydraulic counterbalance valves used in sandstorm to Leonard. We also told Leonard that the production cost of hydraulic counterbalance valves made of special materials has been increased by 40%. Leonard said that if AAK hydraulic counterbalance valves are durable for more than 1 year, even if it is 40% higher, it is cheaper than using the original manufacturer's hydraulic counterbalance valves that need after-sales service twice a year. Last week Leonard emailed that the customer reported that AAK hydraulic counterbalance valves had been used for 9 months and there was no corrosion trace on the surface. The headache corrosion problem should be solved.

 

Leonard privately informed that AAK hydraulic counterbalance valves still have a three-month test period. If there is no customer repair report within 1 year, AAK will be their hydraulic counterbalance valve supplier in the future. I think this is the best return for AAK R & D ability.

 

AAK hydraulic counterbalance valves, which can't be achieved by peers, you can also give it a try!
