Product Questions & Answers

how do you actually lock in a flow setting once you get it dialed where you want it? worried about it drifting on me mid-job

Question by: Kurt W on Sep 6, 2025, 2:22 PM

Once you've got the flow adjusted to where you need it, there's a set screw built into the valve that locks the position down. It won't drift on its own after that. The color-coded dial and numbered readout also make it easy to get back to the same spot if you ever have to reset it, since each full turn of the knob corresponds to one color band.
