A Back Pressure / Pressure Sustaining Valve is an automatic, pilot 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.
