Back-Pressure Regulator

Back-Pressure Regulator

Manufacturer: Vinci Technologies
Model Number: BPR

Vinci offers back pressure regulators designed to regulate the pressure in fluid flow studies. The BPR consists of two chambers separated by a piston with a needle connected to it on the lower side. The upper chamber receives the gas dome pressure and the lower chamber the process pressure. The BPR acts a comparator. When the dome pressure is higher than the process pressure the needle seals off the pressure and maintains the pressure. Inversely when the process pressure exceeds the dome pressure the needle opens up and the excess process fluid flows out. That way, on continuous flow these 2 stages are looped continuously and the process pressure is balanced to the dome controlled constant value.
