LVF Compact Low Dead Volume Back Pressure Regulator

The Equilibar® LVF Series Back Pressure Regulator is a very compact, low dead volume version of our low flow LF series back pressure regulator. It comes exclusively in 1/16″ size ports, either HPLC (10-32) style threads or HiP AF1 style. The LVF has a maximum Cv of 0.01 and a dead volume of 0.23 ml.

Equilibar developed the LVF in response to requests for a smaller back pressure regulator. Many of the requests came from scientists doing catalytic research with multiple reactor systems at a high temperature. In this situation, back pressure regulators are often placed inside an oven where space is severely limited.

The LVF is based on the same novel technology as all Equilibar back pressure regulator, but this miniature version has a diameter of less than 40 mm. The unit has an impressive Cv turndown ratio of 1:100,000.

All of Equilibar’s back pressure regulators feature patented technology based on a dome-loaded, multiple orifice design that is capable of providing high performance across incredibly wide flow rate ranges. In contrast, most traditional back pressure regulators rely on springs and other moving parts that can introduce friction and hysteresis to a process.

The LVF is especially well suited for applications involving catalytic research or gas chromatography. It is also well adapted to provide singularly high precision for microfluidics and micro and nano flow control.
