AAK has Faster Proofing and Higher cost performance than that of German factory

Tony is a purchasing manager of Italian Casappa company, mainly responsible for the purchasing of hydraulic pump components. Last October, Casappa developed a new hydraulic pump and planned to promote this new product at this year's exhibition. During the debugging, the output pressure of the hydraulic pump can not be established several times, which is a little troublesome, because the owner has sent all the invitations to the exhibition to the customers and grandly introduced the functions of this hydraulic pump. The R & D personnel checked and tested each component one by one. It is basically certain that it is caused by the instability of the pilot operated pressure control valve.

The technical team dissected the pilot pressure control valve and found local friction marks on one side of the hole wall of the valve body. The diagnosis conclusion is that the main valve spool is stuck, which should be caused by the concentricity difference between the hole of the main valve body and the hole of the pilot pressure control valve body. The owner asked Tony to re purchase the pilot pressure control valve that meets the technical requirements, which must be solved within 25 days, otherwise he will leave because the exhibition is too important. Tony contacted the original hydraulic valve manufacturer and got a reply that due to equipment, he could not produce high-precision pilot pressure control valves with the exactly same concentricity. At the same time, he contacted a number of hydraulic valve suppliers and they basically replied that they could not do such a high precision pilot operated pressure control valve, which made Tony almost collapse.

When Tony searched the hydraulic valve suppliers in Google, he found AAK HYDRAULIC VALVE. The details page of the hydraulic valve on AAK website made Tony feel that maybe AAK could have a try. He emailed us firstly to ask whether the concentricity of the pilot operated pressure control valve could be consistent. We need the detailed drawings, working conditions and parameters of his whole hydraulic pump to judge. After receiving all information from him, AAK technical team pondered the whole afternoon, with more than 95% confidence, and it would take 15-20 days to complete it.

Tony said he was happy and uneasy. He was happy that some hydraulic valve manufacturer could try this high-precision pilot operated pressure control valve and has a high probability of success. He was uneasy that if AAK HYDRAULIC VALVE did not succeed in proofing, the time would be wasted. We understand his concern. We told him that the reason why we are not sure for 100% is that there is a data that can't be determined. If AAK HYDRAULIC VALVE failed in sampling, then he should not waste time in Ningbo area. We suggest that he also find a hydraulic valve supplier in Europe, so as to sample with AAK at the same time.

2 weeks later, we sent a sample of the pilot operated pressure control valve. 4 days later, Tony sent an email excitedly informing us that the pressure of the hydraulic pump was completely normal after using the pilot operated pressure control valve with the same concentricity from AAK. The owner was very happy that the exhibition would not be affected. 5 days later,
