One must constantly remember that pressure drop which is to occur in the control valve plays almost as prominent a part as flow rate.
However, one or the other of two standard characteristics linear or equal percentage is practically always suitable for any given process. This tabulation supersedes all previous listings since many changes were requiered to bring all ratings in line with actual test data taking into account clntrol use of the critical flow factor, Cf.
Similarly, if the valve is too large, it will obviously pass the required flow, but it will be more expensive than a properly sized, smaller valve.
Although in this example the flow increments are identical, in practice, these values can and do vary from the theoretical.
