Equilibar back pressure regulators are dome loaded. This means they require a 1:1 fluid set point pressure to match the desired inlet pressure. There are many advantages to using our dome loaded design. Some advantages include: Extremely wide range of Cv with a single unit, frictionless operation with no cracking pressure, and no hysteresis as found in traditional spring loaded regulators.
For more information, see how our back pressure regulators work.
Most customers use compressed air or bottled nitrogen to supply the fluid set point signal. Our back pressure regulators can also be controlled by one of our Equilibar electronic set point regulators.
Below you will find some set point kit options for either manual or electronic control.
