Correct me if I'm wrong, but doesn't that only apply to solenoid valves (R77.C)? If this could be lumped in as a solenoid I would be amazed. But I completely agree that an inspector would probably not even feel the need to find a rule to make this not be allowed. Although the debate could be popcorn worthy as long as both sides stayed civil...
