Research Series Back Pressure Regulators

Precision at high pressures and low flow rates

Equilibar® Research Series back pressure regulators solve critical performance problems for laboratory and gas analysis systems worldwide. They are especially popular for applications such as catalysis research and reservoir core analysis.

Equilibar has several different trim styles and many different diaphragm materials in the Research Series designs to help meet many demanding research conditions. The Research Series back pressure regulators work through an incredibly wide range of flow, pressure, and temperature. Materials include Hastelloy, SS316L, PTFE, and FFKM (Kalrez), to name a few.

Maximum temperature ranges of the research back pressure regulators are standard 150°C, with the capability to go up to 200°C (with viton seals and metallic diaphragm) and 325°C (with Kalrez seals and metallic diaphragm). In extreme temperature cases, High Temperature models can be used in processes up to 450°C.

Research Series valve are available in port sizes of 1/16″, 1/8″ and 1/4″ to accommodate most low flow / low dead volume requirements. For larger port sizes and flow rates see Equilibar’s General Service Series and Industrial Service Series valves.

Canadian Registration Number (CRN) certification available on select Research Series models for all territories and provinces. Please contact us for more information.

No matter if your application requires precision pressure control of liquid, gas, mixed phases, or even a slurry, our application engineers can specify a suitable back pressure regulator for your application.
