| Message: | Amador is from a hydraulic equipment company in Bolivia. Some time ago, he encountered problems with a hydraulic cartridge counterbalance valve. A logistics lifting device developed by his company needs to use hydraulic cartridge counterbalance valves. Amador selected a hydraulic cartridge valve manufacturer in Ningbo who has cooperated with him for 2 years to test samples. There was a hidden danger in equipment debugging: when materials rise to a certain height and stay, they will automatically fall down slightly and shake with low frequency. The reason is that the balancing capacity of the hydraulic cartridge counterbalance valve does not match the load. Although the hydraulic cartridge counterbalance valve has no leakage and no abnormal function, it must be optimized. The manufacturer had no idea for optimization and gave up. Amador contacted about more than 10 hydraulic cartridge valve manufacturers, but after a week, it was fruitless. Amistad became very worried. |
