high precision back pressure regulator
The Equilibar precision back pressure regulator provides stable inlet pressure across widely varying flow rates and application conditions. Learn how it works.

Equilibar Performance Curves

The Equilibar® is dramatically more precise than traditional regulators on the market - even regulators marketed as "sensitive" or "precise".

The chart below demonstrates what is most unique about the Equilibar® back pressure regulator. The chart shows virtually flat-line pressure stability across over 6 orders of flow rate magnitude. By using several different diaphragms, the same regulator body can also be used to control pressures from less than 0.1 psig to above 1000 psig.

Performance can vary according to port size and diaphragm selection.
