There is no reason, whatsoever, to leave a tank closed so you can find out in the middle of the night, at 10 degrees, in the rain/snow, that your tank ran out because you just wanted to do that to yourself. Checking the tank takes all of 10 seconds and if you are aware of your usage it is SO simple.

As I said, there is no real automatic valve. And, when the temperatures Get Low enough, nothing is trustworthy due to the expansion and contraction properties of propane. Remember, your operating at less than 11 inches of pressure.
