Equilibar”s high-precision back-pressure regulator provides a wide flowrate window, down to a Cv of 1×10-7. These regulators are solving chatter and low-flow stability problems in many gas research applications, including gas chromatography. The dome-loaded LF Series is capable of handling pressures from 0.02 to 2000 PSIG. With low-flow precision well below 1 ml/min, these regulators perform over a 10,000-to-1 flowrate window. Body material is SS316. Available diaphragms include SS316, PTFE, and Viton.
