For example a valve with a cv of 10 will flow 10 gpm with a 1 psi pressure drop. It allows you to calculate the flow or c v (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points in a network transporting a liquid or gas) and the flow rate. C v calculator for valve sizing. It applies to the factor of the head drop (δh) or pressure drop (δp) over a valve with the flow rate q. The valve flow coefficient according to the jis standard, represents the flow capacity in us gallons/minute of 60° f pure water when it is flowing through the valve with a pressure difference of 1 psi at the specified travel (operation range).
