Flow Regulatorssimulate valveswhich control theflows to buildingsSupply side Hydraulics determines the pressure available at the buildingReturn side Hydraulics determines the pressure required at the buildingto transport water backto pump & chillers

If supply side pressureat the flow control valveis not sufficient the flowcontrol valve will open wideand provide less flow whichcan be accommodated bythe return side
