Sanitary Back Pressure Regulator

Equilibar Hygienic Back Pressure Regulators

Equilibar is proud to offer a series of back pressure regulators with hygienic features for BioPharma and sanitary industrial applications.

They offer advantages for applications such as liquid product blending for consumer and body care products where excellent low flow control can be challenging and sanitary processing is required.

These regulators are made of SS316L and can be fitted with USP Class VI diaphragms. They offer crevice-free design, and are designed to be drainable in certain orientations.

Liquid Blending Applications

One common application for the Equilibar FD Series is liquid product blending or dosing. Many manufacturers of personal care products need to precisely control the amount of perfume, dye, or active ingredient that is injected into a line. Performance of positive displacement pumps can be improved, especially in low viscosity applications, by the addition of a precision back pressure regulator.

An FD Series back pressure regulator, with its unique multiple orifice design, is capable of controlling pressure at extremely low flow rates, allowing a more exact mixture of ingredients during blending. Additionally, the Equilibar FD regulator acts as an isolator to header pressure fluctuations as blended product flows through the header. This keeps downstream fluctuations from adversely impacting upstream flow control equipment.

Equilibar Technology: A Good Choice for Complex Level Control

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
