The PDS valve operator name is an optional table input. This input is used when it is defined in the model and when it is defined in this table. When a component has a valve operator, the valve operator name from the model is compared to the valve operator name in the table (if it is defined). If they are the same, the table entry is checked further. If they are not the same, the table entry is rejected. If the valve operator is not defined in the table, then it is not considered in the table lookup.
