The HT back pressure regulator (BPR) is designed especially for use in low flow applications with high temperature media or high ambient temperatures, up to 450C. It is used for gas, liquid or mixed phase fluid applications where precision low flow upstream pressure control is required.
Back pressure regulators control their inlet pressure to regulate the upstream process by opening up only as much as necessary to hold back the desired pressure at the inlet.
HT regulators come in 1/8″ and 1/4″ port sizes.
Equilibar’s Research Series BPRs are designed to meet the demanding requirements of low flow research and high pressure reactor control applications. All Equilibar Research Series BPRs hold stable pressure across very wide flow ranges, and can handle liquids, gases, or multi-phase fluids. These products can be 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 gas or air “pilot” pressure must be supplied to the dome of the BPR equal to the desired inlet setpoint. This pilot pressure can be supplied by a manual pressure regulator, or by an electronic pressure regulator for computer automation. For more details, please visit our “How it Works” page.
The HT regulators 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.
