1.0 MEANING OF SIGNAL WORDS
A safety related message is identified by a safety alert symbol and a signal word to indicate the level of risk involved with a
particular hazard. Per ANSI standard Z535.4-1998 the definitions of the three signal words are as follows:
DANGER
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death
or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor
or moderate injury.
1.1 SAFETY
WARNING
This equipment is intended for use by trained personnel for firefighting. Its use for other
purposes may involve hazards not addressed by this manual. Seek appropriate guidance
and training to reduce risk of injury.
WARNING
Burst hoses and fittings can result in injury or death. Maximum operating pressure of
TFT's Jumbo Gate Valve is 250 psi (17 bar). Do not exceed 250 PSI on either side of valve.
Per NFPA 1962 3 ½ to 5 inch (90-127 mm) hose marked SUPPLY HOSE shall not exceed 185 PSI (13 bar).
Per NFPA 1962 6 inch (152 mm) hose marked SUPPLY HOSE shall not exceed 135 psi (9 bar).
2.0 GENERAL INFORMATION
The Jumbo Gate Valve is intended for use on the intake manifold of a fire engine, fire hydrant, or in a hose line. When used
on a fire engine, the valve is kept closed while the water supply from a hydrant or another pumper to the engine is being
established. This prevents the pump from sucking air through the intake manifold and losing its prime. Once the supply
hose is filled and under pressure, and the air has been vented from the hose, the valve may be opened to connect the
pump to the water supply.

2.1 CORROSION
The aluminum castings are plastic impregnated, hardcoat anodized, and TFT powdercoat finished inside and out for
maximum corrosion protection. Unique stainless steel wedge gate with polymer seats results in low wear and bidirectional sealing. Hose couplings are attached using polymer bearing rings which provides electrical isolation to help
prevent galvanic corrosion. The effects of corrosion can be minimized by good maintenance practices. See Section 7.0
for maintenance.
2.2 USE WITH SALT WATER
Use with salt water is permissible provided valve is thoroughly cleaned with fresh water after each use. The service life of
the valve may be shortened due to the effects of corrosion and is not covered under warranty.

3.0 INSTALLATION
Make connections to fire hose or fittings on each side of valve. Valve seals in both directions. When the valve is in the
fully shut off position air is bleed from only one side of valve. The valve is factory assembled to bleed air from the
same side as the air bleed knob is on. See section 5.1 for how to change which side air is vented from.
WARNING
Kinks in supply hose may reduce water flow and cause injury or death to persons
dependant on water flow. When this valve is used on a hydrant or fire truck it is
recommended that it be used with an elbow to minimize risk of hoseline kinks.
CAUTION
Valve must be properly connected. Mismatched or damaged connectors may cause
leaking or uncoupling under pressure and could cause injury.
CAUTION
Male fire hose threads are sharp and can cause injury. Be careful when around male hose
threads.
4.0 USE
4.1 SWIVEL INLET AND COUPLING
On gate valve models with elbows, the inlet elbow swivels 360 degrees to help prevent hose kinks, and make connection
of suction lines easier. The inlet can be turned forward or backward to help make connections in tight places if the water
supply is in front of or behind the truck. Male hose thread inlets are locked so that they will not rotate.
4.2 VALVE OPEN AND CLOSE
To open the valve turn the handwheel in a counter-clockwise direction until the handwheel cannot be turned. To close,
turn the handwheel the opposite way until it cannot be turned.
5.0 AIR VENT
This valve is equipped with an Air Vent which will allow the air to escape from the valve when the hose is charged. The Air
Vent is opened by turning the knob counter-clockwise and closed by turning it clockwise.
The vent is tapped 1/4 NPT. A barb fitting and plastic tube may be used to run the vent behind the pump panel.
WARNING
Loss of prime can interrupt water flow and cause injury or death. Always bleed out air with
air bleed valve to prevent possible loss of prime. Valve can be set up to bleed air from
either of its two sides. When installing valve, be aware of which side a particular valve is
set up to bleed from.
5.1 CHANGING SIDES FOR VENTED AIR
Valve is factory
assembled to vent
air from this side.
For best sealing results against a pressurized
source, place pipe plug towards water supply.
SIDE B
Pipe Plug factory installed on this
side. If it is desired to vent air from
this side then remove the pipe plug
SIDE A and reinstall in the threaded hole on
the other side.

7.0 MAINTENANCE
The valve should be disconnected, cleaned and visually inspected inside and out at least once per month. Moving parts
such as hand wheels, gate/seat and couplings should be checked for smooth and free operation and greased as
needed. A silicone based grease such as Dow Corning 44 will exclude moisture and retard the effects of corrosion. Any
scrapes that expose bare aluminum should be touched up with enamel paint such as Rust-Oleum to inhibit corrosion.
Replace any missing or damaged parts before returning the valve to service.
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result
in the inability to unscrew the threads of complete loss of thread engagement
over time. Per NFPA 1962 (1998 edition), if dissimilar metals are left coupled
together an anti-corrosive lubricant should be applied to the threads. Also the
coupling should be disconnected and inspected at least quarterly.
CAUTION
Any alterations to the Jumbo Gate Valve and its markings could diminish safety
and constitutes a misuse of this product.
8.0 WARRANTY
Task Force Tips, Inc., 2800 East Evans Avenue, Valparaiso, Indiana 46383 ("TFT") warrants to the original purchaser of its
Jumbo Gate Valve ("equipment"), and to anyone to whom it is transferred, that the equipment shall be free from defects in
material and workmanship during the five (5) year period from the date of purchase.
TFT's obligation under this warranty is specifically limited to replacing or repairing the equipment (or its parts) which
are shown by TFT's examination to be in a defective condition attributable to TFT. To qualify for this limited warranty,
the claimant must return the equipment to TFT, at 2800 East Evans Avenue, Valparaiso, Indiana 46383, within a
reasonable time after discovery of the defect. TFT will examine the equipment. If TFT determines that there is a

limited warranty, TFT will assume the expenses of repair.
If any defect attributable to TFT under this limited warranty cannot be reasonably cured by repair or replacement, TFT
may elect to refund the purchase price of the equipment, less reasonable depreciation, in complete discharge of its
obligations under this limited warranty. If TFT makes this election, claimant shall return the equipment to TFT free and
clear of any liens and encumbrances.
This is a limited warranty. The original purchaser of the equipment, any person to whom it is transferred, and any
person who is an intended or unintended beneficiary of the equipment, shall not be entitled to recover from TFT any
