Managing Supply Pressure Effect (SPE) in a Regulator
Supply pressure effect, also known as dependency, is an inverse relationship between inlet and outlet pressure variables within a regulator. Learn how to manage this phenomenon in your pressure regulators with tips from Swagelok.
How to Minimize Droop
Droop, or the decrease in outlet pressure as downstream flow increases, can be an issue for all regulators. Watch this video to discover considerations for minimizing droop in a pressure-reducing regulator.
Heated Regulators (KEV Series) Solution Spotlight
Discover how the reliable Swagelok® KEV Series Heated Regulator for analytic sampling systems responds to changes in operator inputs, ambient temperatures, and other operating conditions to deliver consistent, reliable performance.
How to Use a Regulator to Reduce Time Delay in an Analytical Instrumentation System
Time delay is often underestimated or misunderstood in analytical systems. One way to mitigate this delay is with a pressure-controlled regulator. Learn how to manage your analytical system’s time delay with these tips.
From laboratory benches to busy manufacturing facilities and commercial fueling stations, industrial pressure regulators play a crucial role in ensuring fluids are contained and transferred under optimal pressures. If pressure cannot be properly controlled in these applications, test results may be invalidated, processes may be disrupted, equipment may be damaged, and personnel may be put at risk. You need to know the regulators in your system will consistently and accurately maintain pressure levels over extended operating lifespans—all without requiring frequent maintenance, repair, or replacement.
Swagelok pressure regulators provide the consistent, accurate, and lasting performance needed to operate fluid systems safely, reliably, and cost-effectively.
Learn How Regulators Perform
Swagelok has advisors on fluid systems located at authorized sales and service centers around the world to provide local support in choosing between a spring-loaded, a dome-loaded, or one of the many other available regulator configurations. These advisors can also help diagnose regulator problems and customize and build fluid systems that include regulators such as a gas distribution system.
