GUN AND VALVE COMBINATION
The Nelson Big Gun
®
sprinklers are capable of operating in combination with an 800 series control
valve when specified with the ANSI flange connection. The SR75 and SR100 connects with the 2”
size valve. The SR150 connects with the 3” size valve. The SR200 connects with the 4” size valve.
The result is a smooth operating and efficient low pressure loss control. The valves have a fail safe
feature as a normally closed valve.
The control valves are designed for application in harsh environments. High grade corrosion-
resistant materials are used in the manufacturing of the valves. Materials are galvanized steel,
brass, coated ductile iron, anodized aluminum and specially compounded rubber. The valves can
be specified with electric on/off solenoid control and pressure control if needed.
COUNTER BALANCE FOR OPERATION
ON TILTED RISERS
A counter balance kit can be attached to the 100 Series
and the 150 Series gun sprinklers to achieve even rotation
rate when riser is tilted at an angle. It is easy to install and
retrofits existing guns in the field.
OPTIONAL QUICK COUPLING VALVE AND KEY
The SR75, SR100 and F100 guns can be ordered with a
quick coupling key for easy portability. The key is designed
to connect to a 2” or 3” size quick coupling valve. The valve
control can be by manual or electric solenoid.
