Presssure Sustaining Valve, also known as Back Pressure Valve, or Back Pressure Sustaining Valve, is a valve that maintain required pressure of inlet port by opening only as much as required.


What is Back Pressure / Pressure Sustaining Valve?

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.
