  • Controlling Flow With Ball Valves Industrial Controls

    2019-9-19 · Ball valves have a number of advantages over globe valves — better rangeability, turndown, higher-pressure bodies, higher capacity, 0% leakage, and usually, lower cost. Rangeability is the useable flow through a valve, divided by the minimum useable flow. Globe valves used in the HVAC industry typically range from 50:1 for a 6", to only 4:1 for a 1/2".
