A temperature responsive valve (TRV), for controlling a flow of gas, employing a shape memory alloy (SMA) wire. The SMA wire is forced by the flow of gas to elongate at temperatures not exceeding a limit known as the transition temperature lower than the austenitic transition temperature. The elongation at a temperature lower than the austenitic transition temperature may be extensive enough to cause a nozzle of the TRV to be blocked, preventing further passage of the gas.
