A nozzle for use in a hot gas valve is provided that includes a housing, an insert, and a throat retainer. The housing is constructed of an insulating material and has a flow path formed therein. The flow path has a throat section. The insert is made of material capable of maintaining structural integrity at a temperature up to about 5000° F. and is disposed at least partially in the throat section and has a flow path extending therethrough in fluid communication with the housing flow path. The throat retainer is constructed of material having insulating and ablative properties and is coupled between the housing and the insert and configured to retain the insert within the housing throat section.
