Concentric Flanged Butterfly Valve Overall Dimension PN10 . Pn16

DN50 to DN1000    CV Valve-Flow Rate Coefficient

DN50 to DN1000 CV Valve-Flow Rate Coefficient

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

CV=Q(G/△P) 1/2       Whereas: G=Specific gravity, clean water will be 1.0 Q=Max fow rate

△P=Pressure difference, lb/in2

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 10Kpa(1Kg/cm2 ) CV=1.17C
