Flow Coefficient Cv  and Flow Factor Kv  - an explanation and the difference between them - For control valves it is often convenient to express the capacities and flow characteristics in terms of a  * flow coefficent Cv  (pronounced C sub V or just CV) is defined as: * the flow of water at 60 deg F in US gallon/minute at a pressure drop of 1 lb/in2 across the valve.  For example, a valve with a Cv of .03 will flow .03 gallons per minute at 1 psi.  A typical 1/2" ball valve with a Cv  of 28 will flow 28 gallons of water per minute at 1 psi.  The rule of thumb is the larger the Cv number, the higher the flow rate.   The metric equivalent called the  * flow factor Kv  (pronounced K sub V or just KV) is defined as: * the number of cubic meters per hour of water at 20  deg C which will flow through the valve with a pressure drop of 1 kg/cm2 (1 bar).    The connection between Cv and Kv can be expressed as: * Cv= 1.16 Kv * Kv = 0.853 Cv
