    Even the HD ones are rated for 450 degrees and really high pressure. Our systems do not stress any valve out there.

    Anything "full port" really. It's nice to use domestic valves of course but they're likely to be used so infrequently that using an imported valve is somewhat justifiable.

    Look on the valve tag the little sticker attached to the valve handle. It will say "swp" steam working pressure. Most decent quality ball valves are reted for low pressure steam. Some foreign valves may not

    I have been a proponent of valves that have a round handle for steam use.
    Ball valves have a lever handle and if they stick as they do over time, they tend to need to be forced open. When forced open, or sometimes (and often enough) the user slips the valve open to quickly forcing steam into the system. Not a good thing.
    So as a habit and a safety concern, I prefer not to install ball valves on steam.

    The thing is, I prefer ball valves for almost everything else
