| Message: | Yesterday, I received a repeat order for a hydraulic sequence valve from Gary. The first order of this hydraulic sequence valve was placed 3 years ago. Before, I wondered why this hydraulic sequence valve had not been repurchased, thinking that it had been switched back to the United States for production. I really didn't expect to receive the repeat order after 3 years, and the quantity was more than 3 times that before.
3 years ago, Gary’s company had a newly designed hydraulic pump to be produced in Vietnam branch, and the pump needed hydraulic sequence valve. If purchasing the hydraulic sequence valve in the United States and delivering it to Vietnam, it was expected to take 3 months or more. His boss wanted to try purchasing in China, hoping to save half the time. According to the boss's instructions, Gary spent 3 days looking for hydraulic valve factories, selected 5 hydraulic valve manufacturers from more than 10 as their hydraulic sequence valve suppliers, and asked them to send reference samples of hydraulic sequence valves to Vietnam for testing. Gary happily reported the purchasing status to his boss, who was satisfied.
After Gary received these hydraulic sequence valve samples, he arranged the technical department to match the working conditions for testing, but the results were poor. The matching clearance between the valve body and the valve spool of some hydraulic sequence valves was small. After an additional 20% pressurization, the valve hole was deformed and the valve spool would be stuck. All 5 hydraulic valve manufacturers said that after additional pressurization, they were not able to ensure the quality of hydraulic sequence valve. Time has been wasted for more than 2 weeks. At this time, if returning back to the United States to purchase hydraulic sequence valves, he would be scolded by his boss. Gary began to worry.
When Gary browsed AAK website (www.aakindustry. com), he felt that AAK hydraulic valve was some different from the other hydraulic valve manufacturers. |
