Seismic Natural Gas Shut-off Valve: These valves trigger when they detect an earthquake of magnitude 5.1 or higher.

Excess-flow Valve: These valves trigger when they sense a gas leak or overpressure surge somewhere in your gas line.

Earthquake valves protect your home from earthquake-related gas leaks and the fires they cause. When an earthquake hits near you, you may not have the time or presence of mind to worry about your home’s gas line. A safety valve gives you the peace of mind to focus on your family’s wellbeing without distraction.After an earthquake, you simply reset the valve after checking to make sure your gas lines aren’t damaged. If the lines were damaged, the valve ensures that gas doesn’t enter your home until they’re fixed.
