Figure 48  Common Gas 05 – Pressure Reducing Valve

Some of the flow in a pipeline is diverted into a branch line and delivered at 5000 ft elevation, where a delivery pressure of 280 psi.g is required. 


Without a Pressure Reducing Valve the pressure in the pipeline branch will exceed the delivery pressure needed at point D. What pressure loss must be added by a Pressure Reducing Valve (PRV) to maintain the delivery pressure of 280 psi.g?
