Edit Equipment

The Edit Equipment tool is valuable for reviewing the requirements of any piece of irrigation equipment, such as a head, valve, or any given length of pipe.

Metric performance data update (2022)

We've updated our irrigation performance data to port all metric data into its own separate database of values. This change will result in a dramatic improvement in the accuracy of flow and pressure data available to metric users. More information

9. Click Analysis to open the Station Analysis dialog box for a breakdown of the various pressures and flows affecting this valve.


10. You can enter or edit the elevation difference from the Point of Connection (POC) to the valve in this field. This figure will affect the pressure requirements at the mainline.


11. Click View Data to see more information on the selected valve on the manufacturer's website.




Station Analysis

Click Analysis to open a Station Analysis of the valve.


The Station Analysis dialog box provides a breakdown of the various pressures and flows affecting the selected valve, including:


Design Pressure: This number is based on the equipment the particular valve is piped to. When you add equipment such as sprays, rotors, bubblers, drip, etc., you assign that equipment a design pressure at which you want that equipment to function.


Friction Loss: When sizing the zone, the system will account for all lengths of pipe with the given flow within each pipe and render losses per segment, showing a grand total of friction loss from valve to farthest head in that zone.


Fittings Loss: The amount of additional loss based on the slider in the Size Laterals dialog box.


Elevation Loss: If you've set an elevation to a zone manually when sizing OR if you've selected the Use Spot Elevations option when sizing a zone, the system will translate the elevation into its respective elevation loss.


Loss through Valve: Each valve has performance data assigned, based on the manufacturer's specs for that valve. Based on the total flow for that zone, the system will generate the respective loss for the specified valve.

Running a Station Analysis


PRESSURE REQUIRED: Total pressure that encompasses all losses from design pressure to loss through valve.


Pressure Required at POC: This number will only show up if you've sized your mainline. It reflects the PRESSURE REQUIRED (listed directly above this line) plus additional losses through the mainline path back to the POC, including any additional losses for mainline elevation, auxiliary equipment, and meter.


FLOW REQUIRED: Based on total flow generated when sizing the zone. Any equipment piped to that zone will be included.


Precipitation Rate: This value will only show up if the zone has been sized.


Water Velocity: This value, which is based on the Maximum Velocity slider setting and the Actual Velocity value listed in the Size Lateral Pipes dialog box, is used to allow the zone to size properly.

The Station Analysis is a reflection of a particular zone after it has been sized. If for some reason you feel that the numbers in the Station Analysis are not right, based on the equipment attached to said valve, resize your laterals to generate an updated snapshot of that zone.


Selecting a New Symbol

Looking to make changes to the rotary symbol nozzles? Do not use these steps – instead, reference our Our Irrigation Symbols documentation for information on how rotary symbols work.


For more information on assigning a new symbol to a piece of equipment, see our Changing Symbols for Irrigation Equipment documentation.

Equipment Info dialog box, Symbol thumbnail

To select a new symbol for a head, valve, or other piece of equipment, click the preview thumbnail image in the Equipment Info dialog box.




You can then select a new symbol and click OK.

Troubleshooting: You Tried to Edit a Component, and Its Preview Thumbnail is Blank

Equipment Info dialog box, Symbol thumbnail blank

You may have tried to edit a piece of irrigation equipment and found that its preview thumbnail is blank in the Edit Equipment dialog box.


If so, here's what to do.

Replacing a Head, Valve, or Other Equipment

The Replace feature, available in the Equipment Info dialog box, allows you to replace an existing head, valve, or other equipment in your drawing with a different model or series. Note that this tool replaces every instance of the selected equipment model in your drawing with the new model you select.




This tool will only replace the selected equipment with the same type of equipment. For example, you'll only be able to replace a head with another head using the Replace tool.

The Replace feature is not available for rotary heads.


To replace a piece of selected equipment, open the View Data / Edit Equipment tool and select the piece of equipment you'd like to replace.



Click the Replace button in the Equipment Info dialog box.

Equipment Info dialog box, Replace button




You can then select a manufacturer, series, and model for the new piece of equipment. The new model will take the place of all instances of the originally selected equipment throughout your drawing.

When you use the Replace feature for heads, it does not respect the radius reduction of the previously placed heads. Here's the workaround: After running Replace (which will update all the heads in the drawing), remove the new model from the project, and add it back. This time, you can set the radius reduction. As a result, when you place any new heads, they will be at the proper reduced radius.

Many users run the Replace tool unnecessarily. Keep in mind that you can edit the text and model of any piece of equipment directly, without the need to use Replace.
