Watts lfll210-5-m23/4 Gas Shutoff Valve 3/4 Inch

Product Description

The WATTS lfll210-5-m23/4 is a lead-free automatic temperature gas shutoff valve designed for residential and light commercial gas supply systems. This valve features a 3/4-inch connection size and an extended shank configuration that accommodates up to 2.5 inches of pipe insulation, making it well suited for installations where insulated lines run through walls or mechanical rooms. The valve responds automatically to temperature conditions, shutting off gas flow when a set threshold is reached. Licensed plumbers and gas fitters install this valve as a safety device within gas piping systems.

This valve is appropriate for gas supply applications in residential and light commercial settings where automatic thermal shutoff protection is required. The extended shank design is specifically intended for installations involving thick pipe insulation, reducing the need for insulation cutbacks at the valve body. It is rated to 210 degrees F, placing it in the range of typical thermal safety applications on gas lines serving water heaters, boilers, and similar appliances.

Key Features

• Lead-free construction meets low-lead compliance requirements for potable and gas system use
• Automatic temperature-actuated shutoff at 210 degrees F
• 3/4-inch connection size for standard residential and light commercial gas piping
• Extended shank accommodates up to 2.5 inches of pipe insulation
• Designed for straightforward integration into existing gas piping runs

Compatibility

Designed as an OEM-style replacement or new-install automatic temperature gas shutoff valve for 3/4-inch gas piping systems requiring lead-free, thermally actuated shutoff protection.

Installation Notes

Installation must be performed by a licensed plumber or gas fitter in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the gas supply and verify zero pressure at the line before beginning work. Confirm the valve flow direction arrow aligns with the direction of gas flow in the piping system. Do not apply excessive heat during installation, as thermal actuated components may be affected by external heat sources.
