RockAuto.com shows pictures of the EGR valves for the 2.4L and 3.0L engines

The EGR valve on engines with electronic fuel injection systems is controlled by the engine control computer ( ECM ) . EGR valves on computarized vehicles normally have a computer controlled solenoid in line between the valve and the vacuum source. They also often have an EGR position sensor that informs the computer what position the EGR valve is in.There are 2 common types of EGR valves: Ported vacuum EGR valves and backpressure EGR valves. The valve we described earlier is the ported EGR valve, besides this type, there are basically 2 types of backpressure EGR valves; The most common type is the positive backpressure valve, the other one is the negative backpressure valve. It is important to know the difference between positive and negative backpressure valves because they work differently and they are tested differently also. Positive backpressure EGR valve: This type o valve is used largely on domestic models. It uses exhaust pressure to regulate the EGR flow through a vacuum control valve. The stem of the EGR valve is hollow and allows backpressure to enter at the bottom of the diaphragm. When sufficient exhaist backpressure is present, the diaphragm moves up and closes off the control valve, allowing the full vacumm signal to be applied to the upper portion of the EGR diaphragm. This opens the valve and allows recirculation to occur during heavy loads.

so the ported business is the other side of the diaphragm?...still unclear on this "ported" take a trip on a ship or pop open a bottle of sickly sweet bitter wine~
