| Message: | Some time ago, Steven, from a Hydraulic Valve Company in UK, fell in a batch of hydraulic directional valves purchased in Ningbo. There had some email communication between AAK HYDRAULIC VALVE and Steven, but maybe the fate has not yet arrived, we did not cooperate until last month this year. Steven regained his confidence because he had suffered a waterloo and got back a key game here in AAK.
At the beginning of this year, a batch of hydraulic directional valves purchased by Steven in Ningbo were stuck and failed during the test run, resulting in the failure of the whole batch of equipment to start up and run. His customer asked UK company to solve it within 30 days, otherwise there will be a big claim. Steven informed the original hydraulic valve manufacturer of these conditions, but the manufacturer prevaricated that it was a problem caused during the assembly process and had no direct relationship with them. Steven also consulted other hydraulic valve manufacturers. They either replied that the hydraulic valve was not produced by them and could not give the corresponding strategy, or there was no reply. Steven received serious rebuff here and there, and feel stressed.
When Steven contacted AAK HYDRAULIC VALVE, we were willing to cooperate with him to solve this problem because we felt his trust in AAK HYDRAULIC VALVE. Through his email description, we were still not sure what the problem is, and asked him to send us samples.
After AAK HYDRAULIC VALVE received the hydraulic directional valve samples from Steven, we felt that the relative sliding between the middle valve column and the valve body was not smooth. When the whole hydraulic directional valve is disassembled, there are slight scratches on the column surface, the valve body hole has a negative tolerance, and the valve body column hole has plastic distortion. |
