High-Pressure Back Pressure Regulators

Research Series Back Pressure Regulators for High Pressure

Equilibar’s Research Series back pressure regulators (BPRs) offer precision performance for high-pressure applications up to 10,000 psig / 689 bar(g). Equilibar high pressure regulators are designed in standard low flow models for applications such as high pressure reactors, and in ultra-low flow models for applications such as high pressure core testing. They provide precise and stable control for liquid, gas, and mixed phase fluids.

Equilibar now has a new Ultra Low Flow BPR rated to 20,000 psig / 1375 bar(g), called the U20L, that is integrated into DCI Test Systems ABPR-20.

The BPR shown at right, the H10P, is rated for 10,000 psig / 689 bar(g). Because Equilibar regulators are dome-loaded, a pilot setpoint reference pressure is required on the dome reference port equal to the desired inlet pressure (1:1 ratio). This pilot setpoint is typically supplied from high-pressure inert gas bottles, such as nitrogen. Customers generally use a manual pressure reducing regulator to control this reference setpoint, but there are other ways to pressure load the dome of an Equlibar BPR.

New study demonstrates promising method of preventing elevation pressure push-through in biotech manufacturing

A collaborative paper by Ryan Heffner, Equilibar’s Single Use Technology Manager, and researchers with PSG Biotech reports on a promising method of preventing push-through flow in diaphragm pumps, particularly when feed tanks are at levels higher than the process area, as is often necessary due to clean room space limitations. While this study focuses on Read More
