A seismic gas shut-off valve (or earthquake valve) automatically stops your home's gas supply during signifcant seismic activity. By preventing gas from flowing into severed pipes, it drastically reduces the risk of fires and explosions following an earthquake.

How They Work
Manual Reset
Once activated, the valve stays shut until manually reset. This requires turning a screw or lever with a tool, such as a flat-head screwdriver.
Mechanical Trigger
Inside the valve, an internal steel ball rests lightly in a seat. During an earthquake's shaking, this ball is dislodged and drops into the pipe, physically blocking the gas flow.
No Power Required
Because they are strictly mechanical devices, they do not require electricity or batteries to operate. Even if the power goes out, you're still protected.
Protect Your Home and Keep Your Insurance Coverage
Major carriers like Farmers Insurance now require automatic earthquake valves to maintain your homeowner's policy. These mechanical devices instantly cut off your gas supply during a tremor, stopping line breaks from turning into devastating fires.
