HF Research Series Back Pressure Regulator

The Equilibar HF (Higher Flow) precision back pressure regulator is useful in higher flow rate research or reactor applications where the maximum pressures are 1000psi (69 Bar) or less. The HF ‘High Flow’ has the unique Equilibar multiple parallel orifice design for high accuracy research applications. It is particularly useful when mixed gas and liquid phases are both present.

HF regulators come in 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 HF 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.
