Sanitary Back Pressure Regulators
Equilibar is proud to introduce a series of back pressure regulators with hygienic features for the BioPharma and 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.
These regulators are made of SS316L and can be fitted with USP Class VI diaphragms. They offer crevice-free design, and in certain orientations are fully drainable.
See the FD Hygienic Series brochure for more details.
Liquid Blending Applications
The schematic below shows a typical application for the 1/2" EB1FD4. Performance of positive displacement pumps can be improved, especially in low viscosity applications, by the addition of a precision back pressure regulator. The Equilibar's unique ability to control pressure at extremely low flow rates offers benefits for the liquid blending of consumer household and beauty products.
