I venture to suggest you are getting confused with indirect (remote) drain valves where the drain isn't at the lowest point of the tank but is connected to some pipework that transports the water from the lowest point to the valve.

I spoke to a Kingfisher AME friend,who says the drains are Solenoid operated But Electrically controlled manually selected to drain accumulated water from various areas.The outlets are the Wing root areas near the Fuselage.

The fuselage has a few valves to drain the bilge area on take-off and landing on A320's, they open at 2.1psi I think. You can hear the hissing noise in the cockpit on take-off/landing via the door drain grid.

The only aircraft with a "remote" fuel tank water drain I know is the Boeing 737. The center fuel tank sump drain valve is operated by a rod mechanism through an access panel on the lower fuselage skin.
