Andreas Fault Northridge Earthquake 2000 Valve Manual Gas Sensitive Shut off Tool w/Built in Level (3/4")

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. Features This manual shut-off valve actuates during an earthquake of 5.2 or greater, with no false trips, to prevent gas flow into a structure to reduce the risk of explosion or fire. Features an exclusive manual shut-off and release method, no tools required. Simple patented design with a built in level for easy installation. Machined from high strength, solid aluminum. Fully anodized for corrosion protection. Certified by the State of California, the City of Los Angeles, and CSA. 30 Year Hassle Free Warranty. It is recommended that this device be installed by a qualified installer in accordance with the installation instructions.
