AAK hydraulic valve spool never leaks, customer promoted to head of Spain headquarters in China

Update time : 2020-10-26 17:55:41
Fernado is a purchaser from a Spain company, responsible for its company's hydraulic valve purchasing in China. This time, he suffered a big setback. For a batch of hydraulic valves using domestic 1214 steel as valve spool, more than 60% of the hydraulic valves have oil leakage after being used for about 6 times. In the recent week, 72 complaint calls have been received, and even more direct requests for goods return have been made. The headquarter requested him to give solutions within half a month. Fernado, however, was confused and had no idea.
 
In order to find out the cause of the oil leakage, Fernado immediately pulled nearly 50 hydraulic valves from the warehouse for parameter testing, and finally found that there was indeed a widespread oil leakage phenomenon. He learned that although 1214 steel made in China is an easy cutting material, due to the brittleness of the material, the slight deformation caused by careless heat treatment to the valve spool, can not be found and picked out by the naked eyes. In order to save costs, many hydraulic valve manufacturers do not do any inspection and assemble the products directly, and then problems came out gradually during use.
 
Occasionally, Fernado saw AAK HYDRULIC VALVE information on the Internet, and contacted us with the mentality of trying. After listening to his intention, we selected some hydraulic valves by using 40Cr material as the valve spool, and conducted pressure test for many times on the spot. There was no oil leakage phenomenon at all. Fernado's face is full of heavy relief when he saw the parameter list. Fernado took a video on the spot, wrote a comparison report, and sent an email to the headquarters. On the third day, we received a small trial order from him, mainly to replace the hydraulic valve stocks with problems.
 
All the hydraulic valves produced by AAK use 40Cr as the main raw material of valve spool, which is pressure resistant, wear-resistant and not easy to deform. At the same time, after heat treatment, the surface toughness is better and the fatigue resistance is stronger. Although the material price and cost is higher than 1214 steel, it can completely solve the problem of oil leakage, this is what many hydraulic valve manufacturers lack.
 
After the oil spill problem was solved, Fernado gained the absolute trust of the headquarters, so he was promoted to be the main procurement leader in China. At the same time, the volume he purchased from AAK HYDRAULIC VALVE has also increased year by year. We have cooperated with him for 3 years, and the average annual purchase is stable at about 1.2 million euro.
 
AAK hydraulic valve uses 40Cr steel as the raw material for the valve spool, which never leak, this is absolutely different from other hydraulic valve manufacturers.
