"WebJun 15, 2024 · Sizing a flow control valve is more complicated because the flow constriction varies. For example, if you use only the maximum flow rate to select a valve, it could result in selecting an “oversized” valve. It’s important to factor in minimum, maximum, and normal flow rates and use the range of flow rates required. " - Flow rate control valves
