Question by: Floyd S on Dec 31, 2025, 8:50 PM

Will these relief valves hold up okay if they're running pretty much non-stop?

Answer by: Customer Support on Jan 2, 2026, 6:07 PM

Designed for continuous-duty pressure control, these pilot-operated relief valves are well-suited for applications where they'll be operating under constant or varying flow conditions for extended periods.
