LVF back pressure regulatorFletcher, NC—October 4, 2017—Equilibar is pleased to announce the release of the LVF back pressure regulator, a miniature, low dead volume version of its low flow back pressure regulator. The LVF comes exclusively in 1/16″ size ports, either HPLC (10-32) style threads or HiP AF1 style. The unit has a maximum flow coefficient (Cv) of 0.01.

Equilibar developed the LVF in response to requests for a smaller back pressure regulator, said David Reed, operations manager.  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 limited.

As a result, Equilibar made a smaller version of its signature dome-loaded, multiple orifice regulator with a diameter of less than 40 mm. The unit has an impressive Cv turndown ratio of 1:100.000. Due to the size of the regulator, a small process connection of 1/16” is used.

 “The LVF is based on the same novel technology as all Equilibar back pressure regulators,” said Reed.  “All of Equilibar’s back pressure regulators feature patented technology based on a dome-loaded, multiple orifice design that is capable of performing across incredibly wide flow rate ranges.” 

The LVF is especially well suited for applications involving catalytic research or gas chromatography. 

Located in the Blue Ridge Mountains of North Carolina, Equilibar Precision Pressure Control provides custom solutions for the most demanding pressure control applications worldwide.  Equilibar engineers focus on rapid customer response, technical excellence, and a creative, collaborative approach.
