When we talk about matching a pressure regulator to the job, one of the primary tools is the flow curve. Get an article and technical bulletin showing how they work.



  • "Performing Under Pressure (Flow Curves)", by Michael Adkins, Flow Control magazine, May 2012 (4 pages)
  • "Technical Bulletin: Pressure-Reducing Regulator Flow Curves," from Swagelok Company (80 pages)

Michael Adkins oversees Swagelok’s team of engineers dedicated to providing direct technical support to customers in the field. He writes in "Performance Under Pressure (Flow Curves)":

"While one can never achieve the ideal of a perfectly flat flow curve over an infinite flow range, it’s good to know there are ways to enhance a domeloaded regulator’s capabilities to realize very flat flow curves over very broad flow ranges."

pressure regulatorWhen you download Adkins' article, we'll also send you a copy of the Swagelok Company technical bulletin that provides an overview of how to read regulator flow curves for pressure-reducing regulators. It describes some of the complexities, including:

  • Droop
  • Seatload drop or lockup
  • Choked flow
  • Hysteresis, and
  • Supply pressure effect (SPE), also known as dependency

In addition, SPE values and flow curves for Swagelok® KPR, KCY, KLF, KHF, KCP, KPP, KPF, and KHP series pressure-reducing regulators are provided for the full line of maximum inlet pressure ranges and flow coefficients available.
