Seismic Valves

Seismic valves are designed to shut off the flow of gas during an earthquake. They can be used in residential, commercial and industrial applications. Once the valve has shut-off, a simple manual reset is required with no other maintenance.

Our seismic valves are intended to close in the event of an earthquake thus preventing gas flowing into a structure where damage may have occurred. The valve minimizes the potential of a fire or explosion due to the release of natural gas into a commercial or industrial building. These valves are designed to be mounted around meter sets and remain closed until manually reset. A viewing port is built into the valve so that the open or closed indicator can be seen.

Here are some of the standard features:

  • Automatic shut-off in case of earthquake.
  • Available in both horizontal and vertical configurations.
  • 30 year warranty.
  • No maintenance required.
  • Options available:

  • Monitoring system option signals the valve status, either open or closed.
  • Electrical switch for remote indication.
  • Remote actuator when alarm switch is tripped.
  • 3-Way for specialty gasses.
    • Rated Operating Pressure: 7 – 60 PSI
    • Size Range: 3/4″ – 4″ NPT, 2″ – 8″ Flanged
