WebEach curve on the graph traces the amount of flow through the valve at a constant stem position, for different amounts of applied pressure drop. For example, looking at the curve representing 50% open ( C v = 9), we can see the valve should flow about 42 GPM at 22 PSI, about 35 GPM at 15 PSI, about 20 GPM at 5 PSI, and so on. WebWhile creating a curve from an equation, you can define your curve equation using the Cartesian, cylindrical, or spherical coordinate system. Once you specify the coordinate system, you can type the equation into a text editor box accessed by clicking the Equation button. For the coordinate system type specified, you can define the three ...
