ABPR-series Automated back pressure regulator

Description


The ABPR-series represents the pinnacle of automated back pressure regulation technology, designed for both single and multi-phase fluids, and capable of maintaining stable pressure control up to 20,000 psi. The architecture of the ABPR integrates a motor-driven piston pump, a high-precision pressure transducer, and a dome-loaded valve. The valve features a dual-chamber design, separated by a piston that employs a high-strength stainless steel needle coupled with a reinforced PEEK seat on the lower side.  The lower chamber pressure control the process fluid flow, while the upper chamber pressure is regulated by a high accuracy motor driven piston pump, containing nitrogen gas. The Back Pressure Regulator (BPR) serves as a comparator: if the dome pressure surpasses the process pressure, the needle seals the outlet, facilitating pressure build-up. On the other hand, when the process pressure exceeds the dome pressure, the needle retracts, allowing excess process fluid to be released, thereby reducing system pressure. These oscillatory actions result in exceptionally reliable pressure regulation. Through an Ethernet interface and specialized software, the ABPR can be effortlessly programmed to execute complex pressure cycles.
