title: Flattening Pressure Reducing Regulator Flow Curves
description: Droop is a decrease in outlet pressure as downstream flow increases. Every regulator will exhibit some droop, but you can take steps to minimize it.

## Good, better, best: Learn 3 ways to configure your pressure regulator and find out which one will maintain more consistent downstream pressure

This Swagelok Tech Tip Video discusses considerations in design for minimizing droop in a pressure reducing regulator.  See three configurations in action and the flow curves that result. You can also download an article that discusses the same issue [here](https://northerncal.swagelok.com/flow-curves/).

Check out this Tech Tip video from Swagelok that demonstrates regulators in action.   The video discusses how a pressure reducing regulator works, its role in a typical fluid system, regulator flow curves, droop, and ways to minimize droop and flatten a regulator's flow curve. Familiar topics if you have been reading our blog or attending our webinars.  However, this video will take you deeper into the issue by demonstrating three different regulator configurations in action and the flow curves and droop that results.   Please take five minutes and watch the video.  If you would like more information check out the resources below including a video replay of our January webinar and our new guide, "Selection and Sizing of Pressure Reducing Regulators: A Guide to Finding the Right Fit.
