Product Questions & Answers

need to choke down flow one way but still let it come back free, is that what this valve does?

Question by: Warren E on Oct 18, 2025, 9:34 AM

For circuits where you want metered flow in one direction and a free return the other way, this inline flow control is built for that. It uses a needle adjustment to control the restricted direction, and it allows free flow in reverse.
