Product Questions & Answers

Would this work for a lower flow rate, say around 1 GPM?

Question by: Tommy T on Apr 16, 2025, 10:36 AM

This flow control valve is rated up to 3 GPM, so using it at 1 GPM should be no problem. You'll just want to adjust the valve accordingly to get the flow you're looking for.
