    It should work with compressed air too.

    Lunkenheimer valves are good quality. Maybe better than good.

    That would look good on a residential steam boiler! Wonder how much pressure they need to make some noise?

    @EBEBRATT-Ed not sure but I’d guess on the higher side.

    Would be fun to have in the shop some day. On compressed air like @Steamhead said.

    Nice whistle! Most of the ones on the steam tractors and locomotives I operate will make noise at about 15 to 30 psi. How much depends on the whistle type.

    Now, that could get you points with your grandkids.

    It looks like the upper part raises up with steam when you pull down the lever. Interesting how it's beveled at the bottom.

    I'm sure there's normally a chain attached to the lever to keep your hand away from the hot, hot steam, no?
    Often wrong, never in doubt.

    Alan you definitely want a chain or rope to blow them. Ear plugs or ear muffs also help. Most of the boilers that I am around with whistles run anywhere from 150 to 195 psi and they are loud!! Especially the one on the locomotive JS8419. It is operated on 195 psi saturated steam.

    The only moving part is the spring loaded valve at the bottom.
