Isolation Valve Attributes
- ID: Unique identifier assigned to this element.
- Label: Descriptive label for this element.
- Notes: Additional information about this element.
- GIS-IDs: List of associated IDs on the GIS/data-source side.
- Hyperlinks: Associate one or more web link, photo, word processing document, or other file with this element.
- Diameter (Valve): Inside diameter of the valve. Used to calculate the velocity through the valve and a corresponding minor loss when a minor loss coefficient is entered.
- Minor Loss Coefficient: K value in the minor headloss equation.
- Is Operable?: If true, valve can be used in identifying segments.
- Status (Initial): Choices: Open, Closed
- Elevation: Elevation at centroid of junctions, valves, and pumps; the ground elevation at tanks; the hydraulic grade at reservoirs.
- Installation Year: Specify the install year of the element. It does not affect the calculations.
- Zone: Specify the zone for the element.
- Hydraulic Grade: Hydraulic Grade at valve location on pipe.
- Pressure: Pressure at valve location on pipe.
- Flow: Magnitude of flow through isolation valve.
- Velocity: Velocity through the isolation valve.
- Distance from End Point (Unified): Presents the active Distance From End Point for the current isolation valve.
- Is Closed?: True if current isolation valve is closed during the current time step.
