Equilibar is proud to offer a wide range of precision electronic pressure regulators. Full scale ranges available from 0.3 psig (20 millibar) to 3000 psig (68 bar). These pressure controllers are useful for a variety of low to medium flow applications, and are also frequently used to provide the pilot set-point for our dome-loaded pressure regulators. Many pressure ranges are available with ultra high resolution performance. Our engineers will work with you to find the right solution to your automation challenge. Our products are 100% designed and manufactured in the USA, and are supported by one-year warranty.


Application Focus:
Automated Pump Pressure Control System

The schematic at right shows how an Equilibar Back Pressure Regulator can work together with an electro-pneumatic regulator to provide automated pressure control with virtually any type of pump.

Also suitable for pulse generating applications.
