Abstract: The selection of a regulator for a specific application should be based on a thorough analysis of the requirements of the installation. Too often a regulator is chosen without complete knowledge of the operating conditions, and the resultant regulation problems are blamed on the regulating equipment. Regulator selection requires knowledge of the operating conditions-the range of flow and if a factor, maximum and minimum inlet pressure. Other factors must be considered however, if the regulator is properly sized to satisfy the range of operating conditions, other parameters can be satisfied without much difficulty. In addition to rate of flow and inlet pressure conditions, other factors such as accuracy of control, range of outlet pressure adjustment, and shut-off characteristics must be given consideration. Each of the requirements does play a part in regulator selection, and the success of the installation will depend on the foresight given to them.
