Why should I install an emergency earthquake gas shutoff valve?

These valves – also known as seismic gas shut off valves – can sometimes help lower your earthquake insurance, as much as 5% depending on your insurance company.

To help ensure peace of mind, and safety for your family, we use Firefighter Gas Safety Products and Pacific Seismic Products. We understand the lives of your families depend on us, so it is our mission to provide only the most consistently reliable seismic gas valves, of the highest quality, because safety is paramount to us.

How much does it cost to install an earthquake gas shutoff valve in my home or business?

Earthquake gas valves usually run from $345 installed by one of our professional service men. Although we offer emergency professional installation, we do recommend you protect your property and your loved ones by having an earthquake shut-off valve installed ahead of time. You never know when a quake may hit, especially in Southern California and the Greater Los Angeles area.

Pacific Seismic Products (PSP)

Pacific Seismic Products (PSP) is a manufacturer of seismic actuated valves, used for residential, commercial or industrial purposes. Their seismic actuated valves can automatically shut off a natural gas line during an earthquake. They offer specialty products as well, such as both horizontal and vertical configurations, specialty valves, remote actuators, 3-ways, electrical switches and monitoring systems, for individual and unique gas control needs.

Intended to close in the event of an earthquake, the earthquake sensitive valves that Pacific Seismic produces in California can prevent the flow of gas into a potentially earthquake damaged structure. This automatic shut off reduces the potential for fires or explosion, due to the accidental release of natural gas into structures which may contain gas lines, gas appliances, such as stoves, or other gas fixtures, like gas fire places.

Designed to remain closed until manually reset, and to not require any source of internal or external electrical power, PSP’s valves are ideal to prevent escalation of an emergency situation. The valves can be mounted in either a downstream or upstream position of the pressure regulator, or the gas meter outside the structure, but they don’t replace manual, upstream shut-off valves provided in the gas service line.

The mechanisms for PSP’s valves use a swing check valve, and a steel ball resting on a tapered cup-shaped support, making them an acceleration-sensitive trigger. Earthquakes cause a horizontal motion, thereby moving the ball away from the center of the support. The weight of the ball trips a move-able pipe, which causes the valve to begin closing. The valve-flapper is then forced close with the aid of springs, and the valve disc, in the closed position, is held in place by gas pressure. The actual valve trip mechanism is set and sealed in the manufacturing factory. There is a sight glass which allows easy visibility of the status of the valve mechanism, whether it is “Open” or “Closed” will be indicated.
