Product Questions & Answers

How does the 3:1 pilot ratio affect the valve's operation?
Question by: Howard P on Dec 2, 2025, 5:45 PM
The 3:1 pilot ratio in this SystemStak Pilot-Operated Check Valve means that the pilot pressure needs to be three times higher than the load pressure to open the check valve. This ratio helps ensure the valve opens only when necessary, providing reliable operation in hydraulic systems.
