The Chief series of handline nozzles is of constant (fixed) gallonage

design and available in standard pressure (100 psi) flows or low pressure
(50 or 75 psi) flows. The constant flow feature maintains the same flow
rate throughout the stream pattern selection, i.e., straight stream through
wide fog. This makes the Chief series ideal for use with foam eductors
and for the application of AFFF or Class A foams

These nozzles are constructed of durable, lightweight Elk-O-Lite and

are designed to give you many years of trouble-free service. All Chief
nozzles comply with the requirements of NFPA 1964,
Nozzles (Shutoff and Tip), 1998 Edition, as applicable to constant gal­lonage spray nozzles.

SHUTOFF

The ball shutoff portion of all Chief nozzles features 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 operation of open and close. By allowing water to flow over and
under the ball, the cutaway ball 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. Refer t o t h e p ar ts dr aw in g fo r a dj us tm en t and replacement of seats.

TIP

This portion of the Chief nozzle is protected by a heavy-duty ure-

thane 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 features a fully machined waterway for greater flow efficiency
and less turbulence for superior stream pattern. The two-piece, floating
stem is designed to prevent damage to the stem head if the nozzle is
dropped on the tip. The stem head is also stamped with the rated flow
and pressure. For example:

GPM 125 30 185 250 325
psi 75 75 50

If nothing appears on bottom line, flow is rated at 100 psi.

These stem heads can readily be changed in the field. Also, the acetal
spinning teeth or the optional molded urethane teeth located in the tip can
easily be removed and replaced.

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,
you 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.

OPERATIONS

The Chief series is engineered to operate at optimum when supplied
with 50, 75 or 100 psi at the nozzle base. Higher and lower pressures will
affect the quality and reach of the stream. Engine pressure (E.P.) should be
set to provide required nozzle pressure (N.P.), plus the friction loss of the
hose (F.L.), plus any appliance loss (A.L.), plus any elevation loss (E.L.).

E.P. = N.P. + F.L. + A.L. + E.L.

CAUTION

Care should be taken when opening and closing any ball shutoff. Rapid
closure and/or opening may cause “water hammer” or pressure surge
which could cause injury or damage to equipment.

MAINTENANCE AND CARE

The Chief series of nozzles is designed and manufactured to give you
years of trouble-free service. Since the nozzle is the firefighter’s first line
of defense against the fire, it should be treated with care. It is not designed
as a battering ram, sledge hammer or forcible entry tool.

EB-98014

Weekly visual inspections and monthly operational checks should
ensure excellent reliability. These inspections may be done daily in busy
companies. All nozzles should be flow tested before entering any hazard­ous environment to ensure equipment is operating properly.

If the nozzle tip becomes hard to rotate (change patterns), remove tip
from nozzle and clean acme threads between the tip and nozzle body.
Should lubrication be needed, Elkhart recommends a silicone based lubri-

cant (Dow-Corning #7 or equivalent). Use lubricant sparingly. Excess
grease will attract dirt and grit and can cause interference between close­fitting parts.

With a minimum amount of care your Chief will give you years of

excellent service. If you have any further questions pertaining to these
nozzles, please feel free to call on us at any time. Thank you for choosing
Elkhart for your fire suppression needs!
