Valve Curve

A valve curve determines how the pressure drop in a valve varies as a function of the water flow

This curve has the following properties:

• Identification
  • Description (Description, String) - Use a user-friendly description when the item name is not sufficient
  • Name (Name, String) - item name
    Avoid very long names or names containing the following characters: '*', '>', '<', '/', '\', '"', ':', ';', '|', '=', '`', '#', ',', '?'
• Object
  • Priority (Priority, Enum) - Information regarding the item's current state. Can be:
    • Neutral: no issues
    • Critical: A problem preventing the calculation or use of the item
  • Error Evaluation (CurveError, Enum) Result of the data evaluation
  • Curve Data (CurveData, IListClonavel) - the curve data, with the columns:
    • Flow Rate (X, Double) - the flowing discharge
    • Head Loss (Y, Double) - the head loss to be considered

The data are entered into the table and plotted on the graph for better visualization:

It is used when the valve is a Positional Control Valve (PCV) type.
