Product Description
Equilibar LF2 Low Flow back pressure regulator

LF Research Series Back Pressure Regulator

The LF is among the most popular Equilibar back pressure regulators. With pressure range up to 1000 psig (69 Bar), it is used for all types of low flow upstream pressure control in research laboratories.

LF regulators come in 1/16″, 1/8″, and 1/4″ port sizes.

Equilibar’s Research Series is designed to meet the demanding requirements catalyst research and high pressure reactor control applications. All our Research products hold stable pressure across very wide flow ranges, and can handle liquids, gases, or multi-phase mixtures. These products are commonly used with highly aggressive chemicals, and can perform at temperatures up to 450C.

Equilibar Research Series units are 1:1 dome-loaded, meaning that a pilot pressure must be supplied to the dome of the BPR equal to the desired set-point. This pilot pressure can be supplied by a manual gas regulator, or by an electronic pressure regulator for computer automation.

The LF Series are part of Equilibar’s patented multi-orifice design, in which more orifices open up as needed to accommodate increasing flow requirements. This design offers the highest possible precision in multi-phase flow applications.

Our applications engineers offer custom designed solutions for the most difficult pressure control challenges. Feel free to contact us to discuss your particular situation.
