- 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.
- Status (Initial): Choices: Active, Closed
- Specify Local Minor Loss?: If true then the minor coefficent for the element is manually set, otherwise the value is derived from the minor loss library.
- Minor Losses: List of all associated minor losses associated with the element, and can be used to generate the composite minor loss coefficient.
- 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.
- Status (Initial, Transient): Choices: Active, Closed
- Elevation: Elevation at centroid of junctions, valves, and pumps; the ground elevation at tanks; the hydraulic grade at reservoirs.
- Concentration (Initial): Specify the initial concentration for the global concentration at the selected element.
- Age (Initial): Specify the initial age of the fluid at the selected element.
- Installation Year: Specify the install year of the element. It does not affect the calculations.
- Trace (Initial): Specify the initial trace amount at the current location.
- Zone: Specify the zone for the element.
- Flow: Total flow through the valve.
- Velocity: Velocity of flow traveling through the valve.
- Headloss: Change in head across the valve.
- Pressure Loss: Change in pressure across the valve.
- Hydraulic Grade (From): Calculated hydraulic grade at the entrance of the valve.
- Hydraulic Grade (To): Calculated hydraulic grade at the exit of the valve.
- Pressure (From): Calculated pressure at the entrance of the valve.
- Pressure (To): Calculated pressure at the exit to the valve.
- Flow (Absolute): Magnitude of flow through the selected valve.
- Status (Calculated): Choices: Active, Inactive, Closed
- Minor Loss Coefficient (Unified): Displays the current minor loss value for the element, depending on whether its derived or local.
- Age (Calculated): Age at selected element for current time step.
- Trace (Calculated): Trace at selected element for current time step.
- Concentration (Calculated): Concentration at selected element for current time step.
- Has Calculation Messages Now?: If true then the current element has associated calculation warning messages for the current time step.
- Is Closed?: True if the current element is closed during the current time step.
- Is Open?: Set to true if open during the current time step.
- Is Initially Closed?: If true, the initial condition for the control element is "Closed" or "Off."
- Controlled?: Is true if a control action in the current control set references the selected element.
