How to use the chart Example 3: How to find the pressure drop across a valve with a known K v . Steam demand of heat exchanger = 3 000 kg/h Steam pressure upstream of valve = 10 bar g = 11 bar a K v of valve to be used = 40 Using the selection chart: Draw horizontal lines from 11 bar a, and from 3 000 kg/h to meet K v = 40 line. Draw a vertical line upwards from the intersection to meet the 11 bar a horizontal. Read the pressure drop at this crossing point, i.e. ∆ P = 1 bar (approximately).
