Precision Back Pressure Regulation

Equilibar has developed a unique, patented dome-loaded technology that gives its back pressure regulators 5X more precision than traditional spring regulators.

Instead of using a diaphragm to move a valve stem, the Equilibar uses direct sealing between the diaphragm and the valve seat. (How it works) In addition to the incredible precision, this technology offers ultra fast response and control at very low pressures and very low flow rates (Features and Benefits).

An air set-point signal is provided to the Equilibar regulator by either a small manual regulator (for manual applications) or an electro-pneumatic regulator (for computer automation).

Precision Vacuum Regulation

Equilibar also offers patented Precision Vacuum Regulators that offer dramatically more stability at varying flow rates than other vacuum regulators. Using the same fundamental technology as the Equilibar back pressure regulators, the EVR series comes with a small vacuum regulator on top for quick, easy set-point adjustment.

Ultra Low Pressure Regulation

A key focus of Equilibar technology is the control of very low pressures.

We have recently introduced a pressure reducing regulator with the ability to control gas pressures down to 0.02 psi (0.5 inWC). The LPR2 can be used in conjuction with the Equilibar back pressure regulator to provide an effective pressure control system for many critical industrial and laboratory processes.
