The cv (or kv) flow coefficient will be less when the valve is partly closed. It is defined as the flow rate in us gallons per minute [gpm] of water at a temperature of 60 fahrenheit. The bigger the value of c v, the more will be the flow through the valve with a given pressure drop.

In More Practical Terms, The Flow Coefficient C V Is The Volume (In Us Gallons) Of Water At 60 °F That Will Flow Per Minute Through A Valve With A Pressure Drop Of 1 Psi Across The Valve.
It applies to the factor of the head drop (δh) or pressure drop (δp) over a valve with the flow rate q. Flow coefficient (cv) is defined as the number of gallons per minute (gpm) at 60°f that will pass through a full open valve with a pressure drop of 1 psi. This is because the vapor bubbles occupy more volume as the mass of liquid expands during the phase change, creating an additional resistance to flow.
