Placing valves

The Valve tool places an irrigation valve with parameters from a selected manufacturer or a custom valve with parameters that can be specified after placement. Various valves provide a wide array of functions in an irrigation system. Depending on the type of valve, different parameters are available.

● Control or zone valves connect the system’s main line to the associated lateral lines and downstream outlets.

● Master valves connect the entire irrigation system to the water source near the point of connection.

● Zone kit valves consist of valve, filter, and regulator in preassembled kits.

2.Click Valve from the Tool bar to select a resource from the Resource Selector. Select from one of the manufacturer libraries, or select the custom valve from Custom.vwx and set its properties after placement.

3.Click once to place the valve. If placing the valve over an existing pipe or irrigation pipe network, the connecting pipe is highlighted and the valve is automatically connected to the network.

The valve parameters can be edited from the Object Info palette. Available parameters depend on the valve type.

Parameter	Description
Save Valve	Saves the selected valve as a red symbol definition in the active file; this would typically be done for a custom valve, or a valve with modified catalog data
Valve Name	Names the object, which is useful for labels, irrigation schedules, and other worksheets
Note	Adds a note about the object, which is useful for labels, irrigation schedules, and other worksheets, and also for making notes when saving red symbol definitions
Valve Type	Indicates the type of valve
Zone ID	For valves that control a zone, provide an identifier label for informational purposes
Display in Drawing	Select either Design Information or Calculated Information to affect the display of all calculated values and coverage zones in the drawing; see Concept: Design and calculation parameters for irrigation
Design Information
Input Pressure	Specifies the designed input pressure that reaches the valve
Output Pressure	Indicates the designed pressure that exits the valve
Pressure Loss	Specifies any pressure loss caused by the valve
Flow	Indicates the flow rate through the valve when the outlets in its zone operate as specified
Calculated Information
Input Pressure	Displays the input pressure expected to reach the valve when it is connected to a network
Output Pressure	Displays the pressure expected to exit the valve Output Pressure = Input Pressure - Pressure Loss
Pressure Loss	Displays the pressure loss that occurs within the valve
Flow	Indicates the flow rate through the valve as a result of the outlets in its zone operating at their received pressure
Catalog Data
Get From Catalog	Opens the Catalog dialog box, for obtaining catalog data for the selected object (typically, this is for adding catalog data to a custom object that has none). See Concept: Using the irrigation catalog.
Data	Displays the catalog data
Decoder (2-wire) (control, master, zone kit)	Specifies the presence of an electronic 2-wire controller component
Pressure Regulation (control, master, zone kit)	Indicates the use of a pressure regulator; specify the regulated pressure, which prevents the design and calculated Output Pressure value from rising above the regulated limit. Zone Kit valves always have pressure regulation.
Regulated Pressure (control, master, zone kit)	Sets the regulated pressure limit
Flow Control (control, master, zone kit)	Indicates the presence of a flow control limiter
Non-potable (control, master, zone kit)	Indicates that the valve carries non-potable water
Comment 1–4 (isolation, shut off, air relief, vent, check drain, other)	Additional comment fields allow further specifications/information to be added to the catalog data
Modify Catalog Data	Makes the data fields editable; modify the data, which can then be saved as a custom entry in the catalog
Save In Catalog	Opens the Catalog Item Edit dialog box, where the custom data can be further edited and then added to the catalog
Graphics
Symbol Name	Displays the name of the symbol used to represent the valve
Replace Symbol	Selects a valve symbol; choose the symbol from the appropriate category
Symbol Scale	Scales the symbol with respect to the layer scale by the specified scale factor; a factor of less than one decreases the size of the symbol, while a factor of more than one increases its size
Attach Tag/Label	Automatically attaches a Tag/Label object to the object. The last selected tag/label for the object type is applied; click the tag/label to edit its properties (see Adding labels to irrigation objects).
Show Input Pressure	Places a pressure label on the drawing
Show Flow	Places a flow rate label on the drawing
