All performance specifications are based on the stated working pressure
available at the base of the sprinkler.
Radius shown in feet. Data based on 360°.
Note: For the 640, differing arcs cannot be valved together.
Sprinkler radius data collected in Toro’s zero wind test facility per ASAE standard S398.1.
Actual site conditions must be considered when selecting the appropriate nozzle.
