got a system that runs steady all day. is this relief valve ok for continuous duty and still hold pressure pretty accurate?

Question by: Melvin P on Aug 7, 2025, 6:29 PM

For steady, all-day running, it’s a good fit since it’s built for continuous duty and accurate pressure control with constant or varying flows. It’s a pilot-operated, ventable relief that limits system pressure, and it’s rated up to 52 GPM with a max operating pressure of 5000 PSI.
