Here's an anti-siphon valve with manual water shut-off for use with an irrigation system. This thing can go for $20-$25 or more - and are almost always installed in really bad areas for total replacement - so they actually make a kit that replaces the worn out plunger mechanism (which sells for about $10). You just turn off the water, unscrew the large flat cap, and swap out the worn parts. Recap and off you go.
The manual shut-off valve typically doesn't get used all that much, so people don't refurb that portion. Though it's similar to a hose bibb with parts and procedure.
I got this from a customer who brought it in with him to the hardware store. He had backed his car too far under his carport, and bumped the valve, snapping off the 3/4" pipe. I told him the broken stub could be removed, and the valve reinstalled - he could put a rebuild kit in it if he wanted. (But that wasn't what brought him in). He said no, he'd just replace the whole thing, and gave the old one to me. I removed the rusty stub in about 5 minutes, then cleaned it up and checked out the internals - nothing wrong with any of it!
The rebuild kit is like this:
