In this quick boiler tip, we show you how to set up parallel pressure relief valves for maximum redundancy and tighter downstream pressure control. Learn why sizing your small PRV at one-third capacity and setting it 3–5 PSIG below your main valve keeps you running smoothly under light loads—and automatically brings the big valve online when you need it.
