A process control apparatus includes a housing, a process control device disposed in the housing, and a temperature control device operably coupled to the housing for regulating a temperature of an atmosphere internal to the housing. The temperature control device includes a vortex tube and a flow control valve. The flow control valve is coupled to the vortex tube and includes a temperature sensing feature configured to sense a temperature of an atmosphere internal to the housing and configured to move a control element of the flow control valve based on the sensed temperature between a plurality of positions to selectively direct the flow of fluid from the first and second vortex outlets to the atmosphere internal to the housing.
