The metal rod/cylinder that is perpendicular to the two plastic gas ports, and at the opposite end of the unit; is this another port or opening to the gas flow, or is this the solenoid travel shaft or a mounting rod of some sort? I just want to check if this valve has only one inlet and outlet port, or switches between the third port opening to the gas flow.

The metal rod is one of the inputs. When the power is off, the metal rod connects to the middle white plastic port. When the power is on, the two plastic white ports are connected and the metal rod is blocked. Take a look at this image to understand the airflow. https://tinkersphere.com/8138-thickbox_default/solenoid-air-valve-12v.jpg
