SR100 END OF PIVOT SPRINKLER
SR100 Big Gun®
The SR100 Big Gun with an 18 degree trajectory is the most popular Pivot End Gun used on center pivots today. A Big Gun® sprinkler (operating through a complete rotation) on a quarter-section pivot can effectively irrigate up to 20 additional acres (8.1 ha). Considering the costeffectiveness of putting this additional land into production, an end gun alternative shouldn’t be overlooked.

The 100 Series is a perfect fit for solid set irrigation, pivot end gun irrigation, dust suppression and sports field applications. Anodized or Powder Coated units are available, which makes this a great option for mining or wastewater applications. The Nelson 100 Series Big Gun comes as a Full or Part Circle sprinkler with an 18°, 21°, 24°, or 43° trajectory (or 15°- 45° adjustable trajectory). Taper, Taper Ring, or Taper Bore Nozzles are available (TR not available for SRNV). The SRNV100 is the field-proven SR100 with a nozzle valve incorporated. This is a great product that solves many center pivot problems: you can get extra acreage, flush out the system when needed and with no in-line valve there is no friction loss, no turbulence and no plugging. Add-on kits include Low-Pressure Drive Vane Kit, Counterbalance Kit, Secondary Nozzle Kit, 12° Wedge Kit and the Stream Straightener Vane. Can be fitted to a QC Valve or 2” 800 Series Control Valve (QC not available for SRNV100). Connection options include 2” FNPT or FBSP, 2 1/2” FNPT ANSI/DIN, Nelson or Euro Flange for the F100 and SR100 - and the 2” FNPT or FBSP for SRNV100. F100 (Full Circle)
END GUN CONTROL — NO SOLENOID REQUIRED Winner of AE50 (American Society of Agricultural and Biological Engineers) 2001 Outstanding Innovations — the Pivot Gun Control Valve combines a Big Gun® Sprinkler and an 800 Series valve (A2 B7 C3). No solenoid is needed for this gun control system (when a booster pump is used). PRINCIPLE OF OPERATION: The Nelson 2” valve is normally closed. When the booster pump is turned on, the added pressure forces the small amount of water in the valve’s sleeve chamber back into the system, causing the valve to open. When the booster pump is turned off, the system pressure re-fills the valve’s sleeve chamber and closes the valve.
