Regulator Resources

We know pressure regulators are one of the more complex components to select in your fluid systems. That's why we've compiled a host of resources to assist your understanding of the many system variables required, and then help translate these variables to select the correct regulator for your application needs.

Swagelok Western New York is your resource for pressure regulators.

Flow Curve Generator

Use the tool to understand regulator performance in multiple application environments, or compare the performance of up to four regulators in the same application.

Pressure-Reducing Regulator Flow Curves Technical Bulletin

Use this bulletin to learn how to read regulator flow curves for pressure-reducing regulators. It describes some of the complexities, including droop, seat-load drop or lockup, choked flow, hysteresis, and supply pressure effect (SPE), also known as dependency.

Pressure Regulator Selection Strategy Whitepaper

The best way to select a pressure regulator for your application is to examine its flow curve, which is often provided by the manufacturer. The whitepaper covers the basics – understanding terminology and interpreting regulator flow curves – but also covers additional related topics such as droop, choked flow, and hysteresis.

Technical Videos

Our three pressure regulator tech tip videos cover Supply Pressure Effect – what it is, and how to manage it, as well as Droop, an issue for all regulators, and the considerations in design for minimizing Droop in a pressure-reducing regulator.

Managing Regulator Supply Pressure Effect = Pt. 1

Learn what Supply Pressure Effect is, and how to manage it, part 1.

Managing Regulator Supply Pressure Effect = Pt. 2

Learn what Supply Pressure Effect is, and how to manage it, part 2.

Flattening Regulator Flow Curves to Minimize Droop

Droop, the decrease in outlet pressure as downstream flow increases, is an issue for all regulators. Sometimes it is critical to keep the pressure constant as flow changes. Watch this video to learn about considerations in design for minimizing droop in a pressure-reducing regulator.
