Question by: Steve R on Sep 23, 2025, 2:19 PM

what's the max pressure this valve'll handle on a parallel circuit setup?

Answer by: Customer Support on Sep 24, 2025, 4:12 PM

Running parallel circuit, the SD25 is rated up to 4600 PSI. If you're on a series circuit instead, that number drops to 3050 PSI. Worth knowing before you size it into your system, because those are two pretty different limits depending on how your hydraulics are laid out.
