Flow Coefficient Cv and Flow Factor KvFor 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
