| Message: | Amistad is from a hydraulic equipment company in Spain. His purchase has been smooth in the past 3 years. Some time ago, their company developed an automatic hydraulic ladder truck, and the hydraulic cartridge needle valve used was from a local supplier who had cooperated with their company for 3 years. During the commissioning of the hydraulic ladder truck, a hidden danger was found: the ladder truck fell slightly after the operating lever was suspended. After troubleshooting, the root cause was locked in the hydraulic cartridge needle valve. After testing the hydraulic cartridge needle valve individually, there was no leakage and no abnormal function. The manufacturer of the hydraulic cartridge needle valve recommended that another hydraulic cartridge check valve be integrated to assist the hydraulic cartridge needle valve. However, this would change the original design of the manifold and increase the cost, and this solution was rejected by the boss. Amistad contacted more than 10 hydraulic cartridge needle valve manufacturers, but after a week, it didn't work out. Amistad was worried. |
