Then there is a further subset of Listed indicating valves. A ball valve
may very well indicate its position but I don't think they are any Listed as
a fire sprinkler control valve. I think the 5 second rule is what eliminates
them from the Listed variety of a generic indicating valve. So pay
attention to the purpose of the valve and whether it needs to be Listed or
not.

Yes this answered the question, which of course was the answer I thought but
was prompted to ask anyway. Thanks all.

An OS&Y is one type of indicating valve. A Post Indicating Valve (PIV) would
also fall into that category. It wouldn't HAVE to specifically be an Outside
Stem/Screw and Yoke valve.
The indicating portion would be signage as part of the valve showing "OPEN"
or "SHUT/CLOSED" or some other means to clearly show the valve position.
Not sure if that answered the question though!

Can anyone give me a definition of "indicating shut-off valve". My guess is
that it is an OS & Y but don't know.
