This extraordinary precision makes the Equilibar BPR uniquely qualified for high precision, low-pressure applications in the both laboratory and industrial settings such as glovebox and tank blanketing pressure control.
The Equilibar GS Series and BD Series BPRs can both be configured for very low pressure applications. BD Series regulators are for higher flow and GS Series regulators are for medium flow.
Please contact an Equilibar engineer to discuss your low pressure application. They can recommend the model that would be most appropriate for your application parameters.
Low pressure performance
The graph below demonstrates the extremely tight pressure control of a low-pressure BPR model using a delicate polyethylene diaphragm. Based on the customer application, an Equilibar BPR is designed with an appropriately sensitive diaphragm suitable for the application demands.

Special Application Focus:
Precision Ultra Low Pressure Gas Supply System
There are very few if any commercial regulators capable of precisely controlling gas pressure below 0.5 psig / 34 millibar(g) with varying flow rates.
The LPR2 can be used in conjunction with an Equilibar precision back pressure regulator and a flow control valve to provide incredible precision and responsiveness. By venting any gas flow not required by the application, this system can accommodate forward or reverse gas flow at the application without loss of accuracy.
