Seismic Shut-off Valve for Gas Line
A seismic gas shut-off valve is a crucial safety device that automatically stops natural gas flow to a building
during an earthquake, preventing dangerous leaks, fires, and explosions. The valve is installed (by a licensed professional)
right after the meter and before the house and placed to ensure correct orientation (arrow pointing toward the house),
proper bracing, and code compliance. The valve features an internal ball that drops to block gas flow during
significant shaking, preventing fires and explosions after an earthquake, requiring manual reset after activation.
