Cv is the amount of flow, in GPM, that a full open valve will pass at 1 psi differential across the valve. It has to do with the size of the flow area of the valve when full open. Your deltaT question is best referred to our technical journal series called idronics. Take a look at issue #23 "Heat Transfer in Hydronic Systems".
