Testing and Evaluating Pressure Regulator and Relief Valve Applications - Emerson Automation Experts

Testing and Evaluating Pressure Regulator and Relief Valve Applications

Let’s close the week with peek into the labs where pressure regulator and relief valve testing is done.

Emerson-Regulator-LabIn this 4:21 second YouTube video, Emerson Lab Overview, the team managing the lines of regulator technologies provide a look at the test labs and share examples of testing performed. This testing on pressure regulators and relief valves helps to assure successful operation when the regulators are placed into service and to help troubleshoot conditions which may arise.

Some of the industries served with this flow, materials, and environmental testing and application evaluation includes natural gas distribution, oil & gas production, chemicals, refining and liquefied petroleum (LP) gas.

One example shared in the video was a producer wanting to validate a design change on a skid. The testing revealed that the pipe size was restricting flow to one of the relief valves. Further testing helped identify the correct pipe size to solve the need for increased capacity and improved production.

One other example shared was a process manufacturer that had internal corrosion develop on a pressure regulator. The parts were analyzed and a contaminant was discovered to be in the process fluid. As a result of this materials testing, the materials in the regulators were changed.

Watch the video to see several other examples shared and how you can contact your local office to arrange a tour or testing in one of the seven global labs.

You can also connect and interact with other pressure regulator and relief valve experts in the Regulators group in the Emerson Exchange 365 community.

    I have a Victor Inert Gas Pressure Regulator (Victor Model No. SR 4K). It has “Maximum Inlet Pressure 5500 PSIG” stamped on its side. It has two pressure gauges (both 6000 PSIG). My question is would you test and /or certify this regulator for correct and safe operation? If so, what is the charge for this service?
    best regards

    Hi Bill, Thanks for your comment and questions. I checked with some friends who manage our regulator products and here’s what they shared back:

    We could test the performance of the regulator to ensure it meets the manufacturer’s specifications but we would not be able to certify it in any way. It’s likely that the cost to use this testing facility would be significantly higher than the cost of a regulator. You might consider the purchase a TESCOM regulator. If you send us [jim.cahill@emerson.com] the specification, we could get the correct regulator for your application.
