General Service Back Pressure Regulators from Equilibar

General Service Back Pressure Regulators

Equilibar’s GS back pressure valves provide stable pressure control for gases, liquids, and mixed-phase fluids in inlet/outlet port sizes from 1/4″ to 1″. Common materials in stock are SS316L and PVC; depending on your application needs, other materials available for order are Hastelloy C276, Titanium, Monel, Zirconium, Aluminum, CPVC, PVDF, PTFE and PEEK.

The GS Series comes in different trims to suit the process parameters. A GR trim is more efficient for the lower pressures and NR is more robust for higher pressures.

Common applications for the GS Series include fuel cell testing, continuous API manufacturing, pressure bypass control and high resolution flow control.

Contact an application engineer to discuss the requirements of your process.

How do I choose a back pressure regulator?

Choosing a back pressure regulator involves understanding the process parameters of the fluid during the process, including fluid phase (gas, liquid or mixed phase), fluid temperature, range of flow rates and pressure range. An engineer will use this information to size a valve with the proper flow coefficient, a number used to represent how easily fluid flows through the valve. Chemical compatibility or oxygen use will also be a factor in the materials chosen for the valve design or for any special surface treatments required. Sanitary designs are different from general or industrial service designs.
