AAK Hydraulic Pilot Operated Relief Valve Advantage & Feature

Caleb is an old customer of AAK in Mexico and has purchased hydraulic cartridge valves from AAK for 4 years. At the end of last year, he emailed me to discuss 3 issues related to hydraulic pilot operated relief valves.

1. The internal leakage of AAK hydraulic pilot operated relief valve cannot exceed 1 drop/min.

2. Can AAK hydraulic pilot operated relief valve achieve multi-level pressure control?

3. Can AAK hydraulic pilot operated relief valve be customized within 35 days?

Looking closely at these 3 questions, I guess he encountered a problem when purchasing a hydraulic pilot operated relief valve. After communication, it was learned that in September, they developed a multifunctional excavator. Due to time constraints, Caleb purchased the hydraulic cartridge valves from a local hydraulic cartridge valve manufacturer in Mexico, but the test run was not successful.
