Northridge 2000 Valve


Valve Design

The Northridge 2000 valve is a simple patented design with only one moving internal part. A stainless steel ball rests on a pedestal inside the valve when it is in the ON position allowing gas to flow. During a seismic disturbance of approximately 5.2 or greater on the Richter scale, the stainless steel ball falls from the pedestal and plugs the outlet passage stopping the flow of gas. The gas can only be turned back ON by manually resetting the valve. The faceplate has a magnet concealed behind it that lifts the stainless steel ball back onto the pedestal when it is slowly rotated one full turn counterclockwise.

Sight Glass ON/OFF Indicator

The valve is equipped with a clear sight glass to determine whether the valve is on the ON or OFF position. When valve is ON, the internal stainless steel ball can be seen when looking straight down through the clear sight glass. Your eye should be approximately ten inches (10") above the sight glass. When the valve has shut OFF, the internal stainless steel ball cannot be seen.


The Northridge 2000 valve should be installed by a qualified installer in accordance with the manufacturing installation instructions. If improperly installed, failure to function as intended or unwarranted interruption of gas service could result. A qualified person should check for gas leaks before and immediately after turning gas ON by resetting valve.

What does an earthquake valve do?

Protect your home and family by installing a Northridge valve by Seismic Safety Products. Our valve automatically shuts off your gas during an earthquake giving you peace of mind.


Why do you need one?

Scientists recently discovered strong evidence that great earthquakes (magnitude 8 to 9) have repeatedly struck the Pacific Northwest in the past several thousand years, most recently about 300 years ago. This discovery has spurred the reinforcement of existing structures and changes in building codes in the region--measures that will save lives and reduce damage in future earthquakes.

If you live in a MODERATE or EXTREME risk area, and use natural gas. You can help protect your home and family from fires, explosions and gas leaks caused by earthquake damage by installing the NORTHRIDGE valve!

What valve should I get?

The Northridge earthquake on January 17, 1993 was 6.7 on the Richter scale. 72 individuals lost their lives. 11,846 inured. Over $25 billion dollars in damage. 114,039 buildings damaged. Over 12,500 after shocks, ten of which were over 5.0 on the Richter scale. 185 mobile homes burned from gas fires. 700,000 claims filed with F.E.M.A. for gas appliance damage. Up to 50% of post earthquake fires are caused by gas leaks.
