Flow Coefficient Values - Cv Values of Ball Valves

Aug 30, 2019· The coefficient of flow or C v Value is the number of US gallons of water the valve will pass with a differential pressure of 1psi through the valve at 60F.. K v is the metric value of C v and is calculated as K v =C v x 0.85.. C v varies with both style and size of valve, but provides an index for comparing liquid capacities of different valves under a standard set of conditions.
