EGR valves that I have seen are vacuum operated actuators, 2-3 inches in
diameter, mounted to the intake manifold on a "stalk" a couple inches
long.  There are passages inside the head and intake that route exhaust
into the intake, the vacuum valve allows the two to mix.  Computer
engines will probably also have a few wires going to the valve, the ECM
pulse width modifies the vacuum signal to control when the valve opens.
