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.
