Equilibar’s Research Series back pressure regulators offer precision performance for high pressure applications up to 10,000 psig. These regulators provide stable inlet pressure 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.
For Research Series regulators, diaphragms of Stainless Steel 316, Polyimide, PEEK, and Hastelloy are suitable for the high pressure range.
The back pressure regulator shown at right, the H10P, is rated for 10,000 psig. Like all Equilibar back pressure regulators, it requires a 1:1 fluid set-point on the top reference port. This high pressure pilot pressure is typically supplied from high pressure inert gas bottles, such as nitrogen. Customer typically use a manual pressure reducing regulator or a high pressure electronic pressure regulator to control this set-point pressure.

For port sizes larger than 1/4″, see our GS Series products, which are available up to 3000 psig (200 bar).
Because our technology is dome-loaded, a set-point reference pressure is required on our reference port equal to the desired inlet pressure (1:1). Equilibar sells both manual regulators (up to 5000 psig) and electronic pressure regulators (up to 3000 psig) to provide the set-point for these high pressure applications.
The H10P and U10L series are rated for 10,000 psig service.
