WebJan 24, 2012 · People have a misconception about how ball and gate valves work. They work by restricting flow generally by reducing the area the water can pass through, not by reducing the amount of power to a pump. The increase in resistance to flow results in a lower flow rate at the same power rating. WebPressure and volume are two different things. Closing a ball valve would reduce the volume, however that smaller volume of water would have the same pressure behind it. A PRV works with a spring diaphram to reduce the pressure to a set/adjustable level, and is what you need for this problem. 2 level 2 FattymcFatFats · 6y This is definitely correct
