 These
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. This will greatly reduce potential
risk of explosion or fire due to loss of gas
line integrity or uncontrolled flow of gas
after a major earthquake.
