How to use the chart Example 2: How to find the K v value for a non-critical flow application. Steam demand of heat exchanger = 230 kg/h. Steam pressure upstream of valve = 5 bar g = 6 bar a Steam pressure required in exchanger = 4 bar g = 5 bar a Using the selection chart: Draw horizontal lines from 230 kg/h, and from 6 bar a to pressure drop of (6 - 5 = 1 bar). Drop a vertical line from the intersection to meet the 230 kg/h horizontal. Read the K v at this crossing point, i.e. K v = 4.
