Equilibar’s Jennifer Jacober is a design engineer with expertise in flow control solutions for unusually complex applications. She recently helped create an animation video that demonstrates the inner workings of a new Advanced Flow Control Valve (AFC) with direct-sealing diaphragm technology. The valve has specific advantages for applications with multiple challenges and is especially useful Read More

Equilibar now offers an excellent option to provide automated electronic pilot control of our back pressure regulators for extremely high pressure applications such as core analysis or supercritical research. The HP-ERC series of high pressure dual valve electronic controllers is designed to automate dome-loaded back pressure regulators up to 400 bar. Even the most challenging Read More

Equilibar’s back pressure regulators (BPRs) are dome loaded. This means that the pressure setpoint is provided by a fluid that is fed into a chamber on the top (dome) of the regulator. The pressure of the fluid (either gas or liquid) is set by a second regulator called a pilot regulator. The loading mechanism is Read More

Choosing the best method to control the flow of a pump can be complicated. There are several options, each with unique advantages and disadvantages. The Equilibar website offers a number of resources for making a good selection. We also have information about the related topics of pulsation dampening, pump runaway, pump slip, and more. A Read More

While Equilibar technology is known as the gold standard for back pressure control, its unique qualities offer advantages for complex level control applications as well. Using an Equilibar unit for level control could be a good choice in circumstances where there is a wide range of flow rates, varying flow coefficients, varying downstream pressure or Read More

A new how it works video makes it easy to visualize the unique operation of Equilibar’s patented back pressure regulators and vacuum regulators. Created by Pressure Control Solutions –Equilibar’s Northern European Distributor–this detailed animation demonstrates the inner workings of the Equilibar and the way its design elements come together to deliver superior precision and performance. Read More

Ever wondered why your Equilibar Application Engineer recommended a Polyimide diaphragm instead of a stainless steel diaphragm? Because our back pressure regulator has only one moving part, the choice of diaphragm selection is complex by necessity. However, our new Diaphragm Selection page sheds a little more information on the diaphragm selection process. If you are Read More

Jeff demonstrates the amazing precision of the EB1HP1 back pressure regulator through a 40,000 to 1 flow rate ratio while maintaining stable inlet pressure.   The video demonstrates controlling Nitrogen gas at a pressure of approximately 1000 psig, and flowing from a range of 1 ml/minute up to 40 liters/minute (a wide flow rate range Read More
