Abstract
The gas safety valve includes a valve that is solenoid actuated in a fashion to interrupt the flow of gas from the gas line to the stove. A remotely located switch including a key locking mechanism can be mounted at any convenient but safe location. A key activates the switch which in turn energizes the solenoid to permit gas flow to the stove. Mounting of the key locking mechanism remote from the stove is added security. An indicator light reveals whether the gas valve is open, closed or perhaps not connected to a source of electricity.
