QC Valve

The Nelson Quick Coupler makes portable Big Gun® irrigation faster and easier than ever before. A quick twist attaches the gun and key to the valve. Simply connect the hydraulic assist and the gun goes into action. The shutoff and disconnect cycle is just as fast and easy.

Stream Straightener Vane for Big Gun

Stream Straightener Vane (#600V) helps reduce stream turbulence and increases the throw radius.

 

Wedge Kit

The Wedge Kit (#11095, #11098, #11358, #11359) increases the angle of the trajectory.

 

 

 

Counter Balance Kit

This kit is used to help balance the Big Gun on severely sloping terrain. It allows for even rotation when riser is tilted and minimizes any brake variations while reducing stress on the lower unit.

 

 

  

Taper Ring Nozzles

The Taper Ring Nozzle (#TR75, #TR100, #TR150) combines the changeability of a ring nozzle with some of the efficiency of a Taper Bore Nozzle.

 

 

 

Secondary Nozzle

Secondary nozzles can be fitted to all Nelson Big Guns and are used to apply water in-close. This is generally not desirable when Big Guns are used on travelers but may be desirable in solid set applications.

Pivot Gun Control Valve

Combo of a Big Gun sprinkler and 800 Series valve (A2 B11 C3). No solenoid is needed for this gun-control system (when a booster pump is used).

 

 

Solid Set Big Gun / Control Valve Combo

Specify ASNI flange + B17 Ex: A2”B17C2D_E_H3 for 75 & 100 Series Big Guns A3”B17C2D_E_H3 for 150 Series Big Guns A4”B17C2D_E_H3 for 200 Series Big Guns - (B18 is an additional option for the 200 Series Big Gun. This is for the cast iron valve while B17 is aluminum.)

Purge Valve

When traditional end guns aren’t an option, specify the Nelson Purge Valve to intermittently flush the end of a pivot to prevent solids from collecting that are not managed by the pivot sand trap.
