There are three types of gas shutoff devices. These are manual shutoff valves, earthquake sensitive automatic shutoff valves, and excess flow automatic gas shutoff valves. The "California Valve" is a horizontal earthquake actuated gas shut valve. It senses shaking in a residential building above a design level and automatically shuts off the gas. It is activated only in cases where shaking may be sufficient to cause damage to the gas pipe system. The valve is available in sizes to meet all residential applications.

Safety+PLUS Meter Excess Flow Valve protects from fire and explosion when pipes rupture. This type of device is activated in cases when excess gas flows downstream of the device, as in a gas leak. These units can be installed at the meter or at gas appliances.

Earthquake Shutoff Valves and Excess Flow Valves are certified by the State of California. These devices should be installed by a properly licensed and qualified Contractor.
