AAK Hydraulic Cartridge Counterbalance Valve Free of Load Interference

Andreus is from a hydraulic equipment company in Chile. At the beginning of the year, their company received an inquiry for a batch of personalized excavators, and customer needed prototypes. The hydraulic cartridge counterbalance valve in the hydraulic system is the key. Their engineer asked Andreus to purchase the standard parts of SUN hydraulic cartridge counterbalance valves, but the parameters did not match, and SUN was unwilling to customize. They had to work with a hydraulic cartridge valve manufacturer who had cooperated with them for 4 years to make samples. But the test run was not smooth. When the load pressure was applied, the opening of the main valve spool of the hydraulic cartridge counterbalance valve would change, affecting the flow and causing the main engine to shake. The hydraulic cartridge counterbalance valve manufacturer had no solution but to give up.
