Leo, a hydraulic valve customer from North Carolina, recently ordered a hydraulic check valve for forklift hydraulic system. Several approval samples could not be approved by his customer because of "slight error in some parameters". His customer was about to cancel the order. He is very anxious, there has been no suitable hydraulic valve manufacturer to cooperate with proofing.

 

Leo found AAK website on Google and sent an email asking if we could make hydraulic check valve with high requirements. After several times of communication, we learned that he received samples from several hydraulic valve manufacturers but all the parameters of the hydraulic check valves could not meet the standard. He asked whether we could help arrange proofing. To be safe, we asked if we can check the samples and parameters of the hydraulic check valves that are not up to the standard first? A week later, we received the hydraulic check valve samples from Leo. After routine inspection, we found that the quality of these hydraulic check valve samples was good. We were also confused why these hydraulic check valves could not meet the standard.

 

If something goes wrong, there should a problem somewhere. We began to disassemble the hydraulic check valve and eliminate the problem step by step. We found a little fluid mark on the surface of the seal ring of the hydraulic check valve. Is there a mismatch between the seal ring and the medium? In the case of pressure and medium flow, the error of flow parameters does exist. We have found the reason why the samples of hydraulic check valve can not be approved, the NBR seal is not suitable for the forklift hydraulic system. Perhaps few manufacturers will take the time to think and solve this problem. On the contrary, after 2 days of research, trial, analysis and discussion, AAK determined that fluoro rubber sealing ring is more suitable for such media, and its sealing performance and stability are more suitable than nitrile rubber sealing ring.

 

After 7 days, we successfully made several samples of the hydraulic check valves, tested them by the test bench to make sure that the parameters were correct, then we sent the samples to Leo. After receiving the samples of AAK hydraulic check valves, the engineer did not expect that their final customer was very satisfied with all the parameters of AAK samples after testing and analysis. The day after Leo received the samples, we also received his first order for the hydraulic check valve worth more than 3,6000 US dollars.

 

Some hydraulic valve manufacturers are not willing to do simple hydraulic valves, but they are not able to do complex hydraulic valves well. The main reason is that the manufacturers do not have the awareness of craftsmen and ignore the control of details. The reason why AAK hydraulic valve quality has been recognized by customers all over the world in the past decade is that we always control details meticulously, can not tolerate a little sand, and always believe that details determine success or failure!

 

AAK hydraulic valve details control, save you time, AAK hydraulic valve craftsman consciousness, save you effort.
