Message: | 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?
