I want to set null all raster values that fall below the 75th percentile value. E.g. If you classify the raster by quantile method into 4 classes I want to be left with the top 25% percentile. For the raster shown below, 3.154941635 would be used in the set null expression.
I have attempted the following in the Calculate Value tool and a value of 0 is being returned. (source:https://community.esri.com/thread/162022)

For one raster, try to build your model builder like:
SetNull settings:
Expression for SetNull:
Beware that (reference):
Finally, as I said, you should use this model as a submodule used as an iterator to another model to run it against all your rasters (https://desktop.arcgis.com/en/arcmap/latest/analyze/modelbuilder/integrating-model-within-a-model.htm#ESRI_SECTION1_FC4FA1B8DC0D418098AD21B774804821).
