1.0 MEANING OF SAFETY SIGNAL WORDS
Asafety 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 Z535.6-2006, the definitions of the four signal words are as follows:
DANGER DANGER indicates a hazardous situation which, if not avoided, will result in death or serious
injury.
WARNING WARNING indicates a 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.
NOTICE NOTICE is used to address practices not related to personal injury.
2.0 SAFETY
WARNING Quick changes in valve position can cause high pressure spikes due to water hammer and may
result in damaged equipment which could lead to injury or death. Open and close the valve
slowly to avoid water hammer.
WARNING Injury or death can result from burst hoses and fittings. Be sure the pressure relief valve is set
at the proper pressure for the type of hose and equipment you are using. See NFPA 1961 and
NFPA 1962.
WARNING Injury or death may occur by attempting to use a damaged valve.
Per NPFA 1962, the device shall be inspected and tested at least quarterly.
Before use, inspect for damage resulting from:
• Failure to drain valve followed by exposure to freezing conditions
• Exposure to temperatures in excess of 160 degrees F
• Missing parts, physical abuse
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 Kinks in supply hose may reduce water flow and cause injury or death to persons dependant on
water flow. Avoid tight bends to minimize risk of hoseline kinks.
CAUTION Maximum operating pressure 300 psi (20 bar). Do not exceed 300 psi (20 bar) on either side of
the valve.
CAUTION Valve must be properly connected. Mismatched or damaged connectors may cause leaking or
uncoupling under pressure and could cause injury.

3.0 GENERAL INFORMATION
The products in the LDH Suite are lightweight, low friction-loss valves and manifolds that can be used in many water distribution
applications. The robust valve mechanism from the TFT Ball Intake Valve is combined with TFT’s 2.5” quarter-turn ball valves and
folding handles for the ultimate in versatility. Valve seats are field replaceable, and quarter-turn folding valve handles require low
force to move, even under pressure. Automatic valve lock on 2.5” valves maintains valve position while flowing at partial openings.
Folding handles minimize required storage space. Devices include pipe threaded port for pressure gages. All models include a
carrying handle or strap. A polymer bearing ring prevents galvanic corrosion on LDH couplings.

5.0 USE
5.1 VALVE POSITION INDICATOR
To open the valve turn the handwheel or crank until the valve position indicator says “OPEN”. To close the valve turn the valve
handwheel or crank the opposite way until the valve position indicator says “CLOSED”.
5.2 AIR VENT AND WATER DRAIN
DANGER Loss of prime can interrupt water flow and cause injury or death. Always bleed out air with air
vent/drain to prevent possible loss of prime.
This device may be equipped with an air vent/drain which will allow the air to escape from the valve when the hose is charged. The
air vent/drain is opened by turning the knob counter-clockwise and closed by turning it clockwise.
To drain the water out of the valve after use, open the air vent/drain. A ½” Diameter tube may be used to direct the drained water
away from the device.
5.3 PRESSURE RELIEF VALVE
WARNING Do not leave the pressure relief valve in the OFF position. The pressure relief valve is disabled
in the OFF position and offers no protection against over pressurization. The OFF position may
be used for controlled pump testing but should not be used for service conditions. Exercise
great care to avoid water hammer or other pressure spikes when the pressure relief valve is in
the OFF position.
WARNING The Pressure Relief Valve may be damaged if frozen while containing significant amounts of
water. Such damage may to difficult to detect visually and can lead to possible injury or death.
Any time the Pressure Relief Valve is subject to possible damage due to freezing, it must be
hydrostatically tested by qualified personnel before being considered safe for use.
LDH valved appliances may be equipped with a pressure relief valve that can be set to any pressure between 90 and 300 psi. Its
function is to protect the pump and supply hose from excess pressure.Apiece of hose or tubing may be mounted on the round spout
to direct water coming out of the relief valve away from the device. The relief valve may be mounted with its opening facing the front,
back, right, or left. To change the orientation of the relief valve, remove the four 7/16” bolts on the corners of the relief valve flange,
orient the valve in the desired position, and replace the bolts. Use thread-locking compound on the threads of the bolts to prevent
them from vibrating loose.
See LIA-202 Pressure Relief Valve Instructions for Safe Operation and Maintenance.

6.0 MAINTENANCE
This valve should be disconnected, cleaned and visually inspected inside and out at least quarterly for proper function per NFPA1962
section 8.2, or as water quality and use may require. Moving parts such as handles, valve ball and couplings should be checked for
smooth and free operation. Seals shall be greased as needed with a silicone-based grease such as Dow Corning 112. Any scrapes
that expose bare aluminum should be cleaned and touched up with enamel paint such as Rust-Oleum.
In particular assure that:
• There is no damage such as cracks or dents
• There is no corrosion
• The waterway is clear of obstructions
• Pressure relief valve setting indications are readable
• The pressure relief valve opens at the set pressure (See LIA-202 for pressure relief valve test procedures)
Replace any missing or damaged parts before returning to service. Any repaired device must be tested before being placed in
service.
CAUTION Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability
to unscrew the threads or complete loss of thread engagement over time. Per NFPA 1962 (2008
edition), if dissimilar metals are left coupled together, an anti-corrosive lubricant should be
applied to the threads. Also the couplings should be disconnected and inspected at least
quarterly.
CAUTION Any alterations to the device and its markings could diminish safety and constitute a misuse
