The Select-O-Matic series of handline nozzles are the most efficient
and effective fire suppression tools available to the fire service today. The
automatic mechanism in each of these nozzles assures you of a superior
firefighting stream throughout the flow range. The constant flow feature
assures you of the same gallonage throughout the fog and straight stream
patterns. This helps make Select-O-Matics ideal for use with foam
eductors and the application of AFFF and Class A Foam. A built-in flush
feature allows passage of debris from the nozzle without shutting down.
These nozzles are constructed of durable, lightweight Elk-O-Lite and
stainless steel, and are designed to give you many years of trouble-free
service. All Select-O-Matic nozzles comply with the requirements of
NFPA 1964,
Standard for Spray Nozzles (Shutoff and Tip), 1998 Edi-
tion, as applicable to constant pressure (automatic) gallonage spray
nozzles.
SHUTOFF
The ball shutoff portion of all Select-O-Matic nozzles feature double
handle stops and high-strength, aluminum/bronze cast handles for rugged
dependability. The horseshoe handle is large enough to allow operation
with a gloved hand, while the tab handle, although smaller, is less bulky,
yet easy to grip. Both handles are easy to operate.
The hydraulically balanced acetal ball within the shutoff allows for
easy opening and closing of valve. By allowing water flow over and under
the ball, the cutaway design practically eliminates accidental shutdown.
Teflon impregnated neoprene seats give the “self-healing” advantage of
soft rubber plus a lubricated surface to prevent the ball from sticking shut.
These seats may be adjusted without dismantling the entire shutoff. Re-
fer to the parts drawing for adjustment and replacement of seats.
TIP
This portion of the Select-O-Matic nozzle is protected by a heavy-
duty urethane bumper and controls the stream pattern selection and the
flush mechanism. To change from fog to straight stream, rotate the tip to
the right. To change to fog or flush, rotate the tip to the left.
The tip has a fully machined waterway for greater flow efficiency. Low
turbulence allows for better stream quality. This portion of the nozzle
houses the stainless steel spring which activates the automatic mecha-
nism. Do not attempt to disassemble this “spring cell” without a special
fixture. The stem can be removed, however, by removing the jam nut on
the “upstream” end of the stem.
The acetal spinning teeth or the optional molded urethane teeth located
in the tip can be removed and replaced easily.
FLUSH
Many water supplies contain rust and debris which can get trapped
inside the nozzle. This will cause poor stream quality and reduced water
flow capabilities. When this occurs, with water still flowing, the firefighter
needs only to rotate the nozzle tip to the left (past wide fog) as far as it
will go. At this point the tip is in flush position and will pass foreign
material. Once the debris is flushed, the tip can be turned back to original
stream selection for normal operations. If the debris is too large to flush,
the firefighter may have to shut down the hose line and remove the
nozzle. The debris can then be removed from the base of the nozzle or
from around the stem head.
