Horizontal Earthquake Valves
Pacific Seismic/California Valves are earthquake sensitive gas shut-off valves. They are intended to close in the event of an earthquake to prevent gas flow into a structure where earthquake damage may have occurred. The valve reduces the potential for fire or explosion due to the release of natural gas into a structure where gas lines, gas fixtures, or gas appliances.
