The oven uses a
Single Safety Valve
that is bimetal-operated (see Figure 4-16). It has one gas
inlet and one gas outlet, for the combination Bake and Broil burner. The safety valve uses an
electrically-operated device at the gas outlet to control the gas flow to the oven burner. The device
consists of an electric heater coil wrapped around a bimetal strip. One end of the bimetal is riveted
to the plate of the valve. The other end has a rubber seat attached to it that covers the gas outlet.
At room temperature, the spring force of the bimetal presses the rubber seat against the gas outlet.
