About the Research series back pressure regulators

Cv: 0 to 0.6  |  Max. Temperature: 450°C  |  Max. Pressure: 690 barg (10.000 PSI)

Suitable for a broad range of applications

Equilibar® Research Series back pressure regulators are suitable for a wide variety of applications. These back pressure regulators have outstanding performance with excellent rangeability, stability and precision. Furthermore, these back pressure regulators are often a “one size fits all” solution across a wide range of flow rates. Therefore, an Equilibar wide flow range valve can replace multiple valves with a single unit. Four of the models in this series can even cover a Cv range from 10·E-11 up to 0,6. In addition, these four models still have a large overlap, while they have a broad Cv range.

Check out the explanation of the Research-Series in this video. You can find more in-depth information about the various back pressure regulators in the Research Series below.


You can watch the following Equilibar video’s describing the design and performance of research series back pressure regulators.

Applicable even for uncertain process conditions

In practice, the conditions under which a future (experimental) process will operate are often unknown when preparing to build such application. The optimal process conditions often are the parameters that need to be investigated after the set-up is built. The back pressure regulators in the Equilibar ® Research Series are particularly useful to maintain a large variation in design specifications and enable the application of very broad process parameters. A large turndown ratio in pressure range and flow range as well as a large variation in density and viscosity of the process media are possible. These back pressure regulators are an optimal fit for researchers and engineers who do not want to limit operating conditions before start an experiment. These valves allow engineers to try all possible variations in flow rate, pressure range, and media density and viscosity.
