Yes, if there is a belly and a small amount of water laying in the pipe.. The valve is protected by the warmer water still in the tank which would take awhile to freeze.
Put a 5 oz cup of water and a 5 gal bucket full outside and see which freezes first.
Not saying for sure that is the problem, but it is a possibility.
