Product Questions & Answers

flow adjustment on this valve -- can you actually turn the knob while the system is under pressure, or do you have to shut things down first?

Question by: Danny C on Aug 22, 2025, 7:47 PM

You can make flow adjustments while the system is running under pressure, no shutdown needed. The knob also has color coding and numbered readouts, so you can dial in a setting and get back to the same spot later without a lot of guesswork. Once you've got your setting where you want it, there's a set screw that locks it in place so it doesn't drift.
