Frequently Asked Questions

What are the primary applications for a Back Pressure Regulator?

Common applications for back pressure regulators include gas sales lines, separators, heater treaters, free water knockouts, and flare lines.

Different options are available to accommodate corrosive or erosive environments. This includes different elastomer options as well as stainless steel component and trim options.

MWP depends on multiple factors such as end connection type, shell material type, and if the regulator is a standard pressure or low pressure regulator. Similarly, temperature ranges will be dependent on the elastomer option that is used on the soft goods in the assembly.

Typically, the standard process media is natural gas. However, certain back pressure models can accommodate wet gas and mixed liquid/gas process media.

The Back Pressure Outside Supply (BPOS) Regulators can function in wet gas conditions.

The Spring Loaded Back Pressure Regulator can maintain a setpoint on liquid or gas systems where 0 to 125 psig adjustable pressure is desired.

Master Repair Kits are available for all regulators. Maintenance is recommended to be performed at least once a year. However, this frequency can increase depending on the application and potential changes in operation conditions.
