Abstract
This present invention relates to a fluid flow control device, such as a valve in an internal combustion exhaust pipe. The fluid flow control device includes a valve assembly and an actuator assembly. The fluid flow control device further includes a cooling ring positioned between the actuator assembly and valve assembly in order to thermally isolate the sensors, controllers and other elements of the actuator assembly from heat that may be present in the valve assembly.
