We've used an air actuated sprinkler valve similar to this on ours for years and it's worked great.

Just for the fun of discussion. The liquid CO2 tank we use isn't legal either...

Although the debate could be popcorn worthy as long as both sides stayed civil...

You have a point. I think the correct answer is only components listed in R77 can be used. Pneumatically operated gate valves aren't on the list.

I like hot sauce with my popcorn. It would be fun to see how many inspections you could make it through.

I would think at least two... Those would be the one I do and the one done by our student captain though. And I'm thinking I would probably flunk it based on the rules as written.
