Choosing the proper regulator configuration can reduce droop

Arumpanayil, S., Swagelok Company

Many factors go into selecting the proper regulator for your system. One of those factors is sensitivity to changes in outlet pressure as downstream flow fluctuates, which is often characterized as “droop” as illustrated within a regulator’s flow curve.
