Seismic 3/4" Vertical, Bottom In 60 PSI

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.
