1.0 MEANING OF SAFETY SIGNAL WORDS

A safety related message is identiﬁ ed 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 deﬁ nitions of the four signal words are as follows:

DANGER indicates a hazardous situation which, if not avoided, will result in death or serious

DANGER

WARNING

CAUTION

injury.

WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.

NOTICE is used to address practices not related to personal injury.

NOTICE

2.0 SAFETY

Quick changes in valve position can cause high pressure spikes due to water hammer and

WARNING WARNING

may result in damaged equipment which could lead to injury or death. Open and close the valve slowly to avoid water hammer.

The Pressure Relief Valve will open to relieve excess pressure but it may not have enough ﬂ ow capacity to protect against large pressure spikes such as those caused by water hammer. Excess pressure can cause equipment failure and directly or indirectly lead to injury or death. Always operate valves slowly to avoid the risk of water hammer.

Injury or death can result from burst hoses and ﬁ ttings. 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.

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 This equipment is intended for use by trained personnel for ﬁ reﬁ ghting. Its use for other

purposes may involve hazards not addressed by this manual. Seek appropriate guidance and training to reduce risk of injury.

Kinks in supply hose may reduce water ﬂ ow and cause injury or death to persons dependant on water ﬂ ow. Avoid tight bends to minimize risk of hoseline kinks.

The valve may be damaged if frozen while containing signiﬁ cant amounts of water. Such

WARNING

CAUTION CAUTION

damage may to difﬁ cult to detect visually and can lead to possible injury or death. Any time the valve is subject to possible damage due to freezing, it must be hydrostatically tested by qualiﬁ ed personnel before being considered safe for use.

Maximum operating pressure 300 psi (21 bar). Do not exceed 300 psi (21 bar) on either side of the valve.

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 LDH Gated Wye is a lightweight, low friction-loss valve that can be used in many water distribution applications. Dual robust valve mechanisms from the TFT Ball Intake Valve are streamlined to a large waterway for the ultimate in versatility. Valve seats are ﬁ eld replaceable, Devices include a 300PSI pressure gage and quarter turn air vent and drain valve. Two robust carrying handles make for easy deployment. A polymer bearing ring prevents galvanic corrosion on LDH couplings.

3.3 CORROSION

Hose couplings are attached using polymer bearing rings which provide electrical insulation to help galvanic corrosion. The parts are then hard anodized, and ﬁ nally powder coated, inside and out, to help prevent corrosion. The effects of corrosion can be minimized by good maintenance practice. See section 6.0 MAINTENANCE.

Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability

CAUTION

to unscrew the threads or 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 couplings should be disconnected and inspected at least quarterly.

3.4 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.

4.0 INSTALLATION

4.1 CHANGING OFFSET OF CRANK HANDLE

When equipped with a crank handle, two offset positions are available to adjust the swing radius of the crank and knob as shown in the ﬁ gure below. The longer offset position offers reduced effort to operate the valve. The shorter offset is available to avoid interference with other equipment. To change the offset, remove the two ¼”-20 x 1/2” button head cap screws from crank. Place crank in desired position and replace screws.
