I think what Al was saying that using port size and hose ID is just a way of restricting flow like quoting a CV value.
Using CV can be pretty confusing because some valves give flow rate and some give CV which is not the same number. Eliminating the CV restriction and just using port size and hose ID is much easier to understand and inspect.

right, so if a solenoid has a 1/8 NPT port, and the Cv of the 1/8 NPT is 0.32, then how can the Cv of the solenoid which includes said port and internal restriction be 0.75?
