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). These regulators provide stable control across widely varying flow rates, for liquid, gas, and mixed phase fluids.

In addition, Equilibar offers the EPR-3000, a high-pressure electronic controller that provides automation solutions for applications involving pressures up to 3000 psig / 206 bar(g).

In the Equilibar BPR, the diaphragm is the only moving part. For high-pressure applications, diaphragms are available in Stainless Steel 316, Polyimide, PEEK, and Hastelloy. Discuss your process needs with an application engineer.

The BPR shown at right, the H10P, is rated for 10,000 psig / 689 bar(g). Like all Equilibar BPRs, it requires a 1:1 fluid setpoint on the top reference port. Because our technology is 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 typically use a manual pressure reducing regulator to control this reference setpoint.

One common application where U10L and H10P BPRs are used is in core pressure testing.
