The H3PF2 is a 1/4 port variant of the H3P series that offers higher maximum flow rates. This additional Cv capacity is often useful for mixed liquid and gas phase reactor outlets that can experience intermittent surges with momentary high output flow rates.
LF / HF / HP Units
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 (HP, HF, 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.
