  • What is the reason behind installing the DRV and Control

     · DRVs and control valves are used to regulate the chilled water flow rate. We need to balance the flow rate considering the pressure drop in the coils of the AHU/FCUs.Hence while putting the valves in the return the flow measured is considering the pressure drop in the coils also and therfore you will get the accurate water flow in gpm while water
