The BR series of backpressure regulators (photo) features a blockage-resistant design geared toward supercritical CO2 extraction, as well as other processes in which clogging, blocking or freezing are potential problems. The BR series relies on internal passages to eliminate convergence points for the build-up of ice and high-viscosity oils. This design allows for precise backpressure regulation during processes involving gas expansion. BR devices are available for pressures up to 5,000 psi in standard trim, as well as pressure ranges up to 10,000 psi with high-pressure trim. — Equilibar Precision Pressure Control, Fletcher N.C.
