Definition of a Back Pressure Regulator Valve
Back Pressure Regulator Valve, also known as a Back Pressure Valve, is a device that maintains a defined pressure upstream of itself (at its own inlet).
A Direct Acting Back Pressure Regulator Valve is an automatic, direct active controlled valve that activated by the pressure of the pipeline. The valve will maintain a steady, predetermined pressure at the upstream of a pipeline.
The valve gate is normally closed. Gate will open once the upstream pressure exceeds the required set-point, thus reducing its upstream pressure. Gate will resume close position once upstream pressure falls below the set-point.
