Back Pressure Regulators
Equilibar's instrument series back pressure regulators solve critical performance problems for laboratory and gas analysis systems worldwide.
Using diaphragms of varying thicknesses, our regulators operate in the range from below 1 psig to 5000 psig.
Our ultra-low flow rate performance down to 1E-7 Cv helps eliminate pulsing or chatter caused by over-sized regulators.
