You probably have the older style 3 contact valve, it works the same as the later ones. A new later style valve will block airflow very well when blowing in either top or bottom port. Woiuldn't be surprised to detect some leakage with various liquids you tried.
Have you checked the coil resistance and ECU resistance?
The earlier valves had brass coil separators that would wear. Did you notice any brass shavings or dust?
If the valve disc snaps back and forth with the 9V battery (good idea) the valve is functional to some degree. There is always the possibility for the valve to act up when it is installed. Hold the valve in different positions when snapping the disc and see if it always switches like it should. Especially check when the base of the valve is horizonal and vertical. If the valve is worn the disc can catch in the internal center port slots. Holding the valve with the base vertical and rotating it to different positions while snapping it may cause the disc to catch in the slots.
