Senon was troubled by unstable Hydraulic Cartridge Counterbalance Valve for 6 months, and AAK solved

Senon is from a Spanish hydraulic equipment company. At the end of last year, their customer customized two sets of hydraulic power units for ocean ships, and needed to customize the hydraulic cartridge counterbalance valves. Senon chose a hydraulic counterbalance valve manufacturer who has cooperated for 3 years to make samples. During the equipment commissioning, it was found that the pressure supply was unstable and the hydraulic system was tested separately, but there was no abnormality. The boss questioned the team's performance.

When browsing on Google, Senon found AAK webpage and left a message: Is the instability of hydraulic cartridge counterbalance valve caused by a hidden danger in design or an unqualified precision?
