Busted Febco backflow loop - sprinkler system

Hello. Before the winter season, I thought I winterized my sprinkler system backflow valve properly. To the "loop" that comes up on the side of my garage, I shutoff the water inlet valve, and opened the two small bleed ball valves to release the water. The backflow valve did not bust (like it did a previous year), but instead, it looks like the valve casing busted instead. Please take a look at the image attached.

My questions are:
  1. What replacement part must I order? I ordered Febco backflow valve when I had to replace that the other year.
  2. I assume I must shut off my water-main first before repairing this? I cannot see any other isolation valve to close before conducting this replacement work.

Your arrow is pointing to a frozen/busted out valve. That doesn't look like part of the backflow valve and should be replaceable without replacing the valve.

Some questions.....
I see the water line is insulated to just below that valve. Is that the actual line to the water main ?
Does that go inside the house or connect outside to the water main ?

If there are no other shutoffs before that..... you will need to come up with a different/better way of insulating that shutoff valve. That shutoff valve stays full of water which is why it cracked.

You drained the backflow valve so it should be ok.

Below the backflow is the supply line to the sprinkler system.

Bet that line goes into the hose and is connected to the main with a valve.

That portion of the line needs to be drained also to winterize!!

The pipe coming up is the supply line based on the flow arrow on the valve.
