Question by: Travis B on Mar 29, 2025, 8:16 PM

what's the max pressure this valve handles in a parallel circuit setup?

Answer by: Customer Support on Mar 31, 2025, 8:07 AM

Running parallel circuit, the SD25 tops out at 4600 PSI. If you're on a series circuit, that number drops to 3050 PSI. Worth knowing before you spec it into anything that's pushing the upper end.
