Cv = when value entirely opened, pressure difference in both sides of valve ill be 1 pound/inch2, when fluid is 60° F clean water, flow volume of per gallon/min. flowing through valve.

Cv = Q √G/DP

Whereas: G = Specific gravity, clean water will be 1.0
Q = Max. flow rate.
DP = Pressure difference, lb/ln2

C = The valve Cv is the flow rate (m3/h) of pure water at normal temperature passing through the valve when the valve disc is fully opened and the pressure differential between the two ends of the valve is 100KPa (1Kg/cm2).
Cv = 1.17 C

Performance curve of flow rate

Note : Performance curve of flow volume means the relationship between open degree of valve and flow volume, normally butterfly valve suitable to use in control flow. When valve’s open degree under 30, not recommend to use in flow volume control.
