Product Questions & Answers

what's the pressure range on this valve and is 3000 PSI actually the top end or just a typical rating?

Question by: Bobby G on Nov 24, 2025, 9:15 PM

The adjustment range runs from 1500 to 3000 PSI, and yes, 3000 PSI is the stated maximum operating pressure for this valve. So if your system runs anywhere in that window, you've got room to dial it in precisely using the knob and jam nut adjustment. Anything beyond 3000 PSI would be outside what this valve is rated for.
