Hydraulic Cartridge Needle valve with 3 Functions, AAK boosted the Hot Sales of Equipment with High

Amistad is from a hydraulic equipment company in Spain. 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.

Amistad found AAK while browsing Google and left a message: How to optimize the hydraulic cartridge needle valve for hydraulic equipment with abnormal lifting? I guessed that he was in trouble when purchasing hydraulic cartridge needle valves. After communication, I learned the above story.
