3”3”
3” for model 150 guns) and (4”4”
4”4”
4” for model 200 guns). The bolts which
are needed for connecting the ANSI flanged gun must have thread 1/2-13 UNC-2B. This thread is tapped into the holes which are used for
connection of the flange to the riser flange. To get the 4” ANSI flange on the F200, an adapter is required (part #10565). The (8) flange holes are
threaded 1/2-13 UNC-2B. The adapter (part #10565) is sold separately. Bolts for the (8) threaded holes are not shipped with the flange adapter.

RISER STABILITY AND THRUST FORCE
2/05
The thrust force for the Big Gun can be calculated by knowing the flow rate through the gun and
the nozzle pressure of the gun. The following equation shows the relationship.
(1)
where, T = thrust force of the nozzle (lb.)
P = nozzle pressure (psi)
Q = flow rate (gpm)
As seen in the diagram above, the thrust force is directly opposite the nozzle exit. Since the thrust force
(T) is now know, the horizontal (H) and vertical (V) thrust force can be calculated using trigonometry.
H = T cos (gun angle from horizontal) (2)
V = T sin (gun angle from horizontal) (3)
The tables below show values of thrust force (T) and horizontal thrust force (H) for the 150 and 200
Big Guns of varying pressures and nozzles sizes.

Specify gun connection:
ANSI flange
Specify 800 Series valve:
A2”B7C2D1E1H1 for 100 size gun
A3”B1C2D1E1H1 for 150 size gun
A4”B1C2D1E1H1 for 200 size gun
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.

NELSON QUICK COUPLING VALVE
2" QC SPECIFICATION
The Nelson Quick Coupling (QC) valve and key are designed to be used in conjunction
with the Nelson SR75 and SR100 sprinkler guns. The valve, key and sprinkler are
necessary for operation.
The valve inlet is to be connected to the water supply pipe system. The valve can be installed below ground level in
a 10 inch round valve box or above ground level on a supported riser pipe of 2" or 3" diameter size. The valve outlet
is normally closed to flow and can be opened only with the quick coupling key.
The key is designed in such a manner as to allow direct connection to the sprinkler gun base. The key can also be
connected to the sprinkler gun using a 2 inch diameter male x male nipple (the maximum nipple length approved is
12 inches). The key is designed to connect directly to the valve. The key is easily attached to the valve by a quick one-
quarter turn that locks the key and valve together.
Opening the valve is done by connecting the key hydraulic pilot to the valve. The key operates hydraulically pressing
the valve seat to the open condition. When the valve is opened, the hydraulic pressure locks the valve, key and gun
together to become a very ridged and stable unit
Operating Range
Pressure range: 30 psi minimum, 125 psi maximum
Flow rate: 25 gpm minimum, 250 gpm maximum
Water temperature range: 32oF to 150oF

Product Materials:
Valve Body Cast Iron and Brass
Valve trim Brass
Seals (both valve and key) BUNA N
Key body Stainless Steel and Cast iron/aluminum
Key Diaphragm Buna N/Dacron
Internal springs Stainless steel

Application fluid: Water only.
Air venting design: The Nelson QC valve is designed to manually vent the air that may be
trapped under the valve. This can be done by using the pilot opening
handle to vent the air before connecting the key.
