Symbol for motorized valve?

I'm working on a system with a motorized ball valve. It's a basic 120v unit with built-in limit switches and two inputs... one opens and one closes. How are these types of valves typically documented on an electrical schematic? I've Googled for "motorized valve symbol" but all I can find are fluid piping symbols. I'd like to hear how others are doing this.

On an electrical schematic, I would probably just draw it as a motor with wires for forward and reverse, but I did find this:

I'm sure someone will chime in with the 'correct' symbol though...

Here is a drawing I did for a bunch of valves like that. Hope it helps.

Thanks to both of you, this gives me some options.
