Back Pressure Regulators & Valves

We can supply several unique solutions for precision pressure control for many Industries and Research Projects. One of our primary technologies is our direct-sealing diaphragm back-pressure regulators, which also include our precision vacuum regulators that can operate at very low pressures and very low flow rates.

Key Technologies

Precision Back Pressure Regulators 

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, our BPR uses direct sealing between the diaphragm and the valve seat. In addition to the incredible precision, this technology offers ultra-fast response and control at very low pressures and very low flow rates. 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, they use a flexible diaphragm as the only moving part.  This diaphragm seals directly against the internal valve orifices, thus eliminatig stiction commonly found in traditional vacuum control valves. The lack of friction allows us to control vacuum to a very high resolution. The EVR series comes with a small vacuum regulator on top for quick, easy set-point adjustment.  The pilot regulator can be supplied as a manual or electronic device.

Ultra Low Pressure Regulation

A key focus of Equilibar technology is the control of extremely 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 conjunction with the Equilibar back pressure regulator to provide an effective pressure control system for many critical industrial and laboratory processes.
