Little Firefighter LFVAGV-75 Earthquake Vertical Gas Valve

Product Description

The LITTLE FIREFIGHTER LFVAGV-75 is a 3/4-inch earthquake-actuated vertical gas shutoff valve designed to automatically stop gas flow when seismic activity exceeds a set threshold. Installed inline on residential or light commercial gas lines, the valve closes without electrical power, relying on a mechanical sensing element to detect motion. Licensed plumbers and gas fitters install this valve as part of a seismic safety system. The 3/4-inch pipe size suits a wide range of typical residential gas supply lines feeding appliances such as furnaces, water heaters, and ranges.

This valve is intended for vertical-mount installations on natural gas or liquefied petroleum gas supply piping. It is commonly specified in jurisdictions where seismic shutoff valves are required by local plumbing or gas codes, particularly in earthquake-prone regions. The vertical mounting orientation is critical to proper sensing element function, and the valve must be installed on a rigid section of pipe per applicable code requirements.

Key Features

• Automatic mechanical closure on seismic event — no electrical power required
• 3/4-inch pipe connection suits standard residential gas supply lines
• Vertical mount orientation for correct seismic sensor alignment
• Applicable to natural gas and LP gas systems
• Manual reset required after actuation, preventing unintended restart

Compatibility

Designed as an OEM-style seismic gas shutoff valve for 3/4-inch residential or light commercial gas piping systems where a vertically mounted earthquake valve is required.

Installation Notes

Installation must be performed by a licensed plumber or qualified gas fitter in accordance with local plumbing and gas codes. Shut off the main gas supply and verify zero pressure in the line before beginning work. The valve must be mounted in a true vertical position on a rigid, vibration-free section of pipe to ensure accurate seismic response. After installation, inspect all joints for leaks using an approved gas leak detection solution before restoring service.
