Control valve sizing and flow coefficient Cv calculation
WebC v Calculator for Valve Sizing. This calculator can be used to help select a valve with enough flow capacity for a given application. The valve flow coefficient (C v) is a … As previously shown, the basic liquid-flow equation relating volumetric flow rate to pressure drop and specific gravity is: Q = C v P 1 − P 2 G f. Where, Q = Volumetric flow rate of liquid (gallons per minute, GPM) C v = Flow coefficient of valve. See more Control valves are rated in their ability to throttle fluid flow much in the same way resistors are rated in their ability to throttle the flow of electrons in a circuit. For resistors, the unit of measurement for electron flow … See more The flow coefficient of a control valve () is a numerical value expressing the number of gallons per minute flow of water the valve will pass with a … See more The flow capacity of a valve () is a quantitative rating of its ability to pass a fluid flow for a set of given pressure and fluid density conditions, defined as the flow rate of water in gallons per minute through the valve given a … See more Sizing a control valve for gas or vapor service is more complicated than for liquid service, due to the compressibility of gases and vapors.
