Abstract
A gas valve comprises the combination of a control valve having a valve body made of polymeric material and a thermally responsive shutoff valve having a metal valve body. The shutoff valve is connected upstream of the control valve and is adapted to be connected to a gas source. The shutoff valve is effective for terminating flow of gas to the control valve in response to exposure to an abnormal temperature value.
