A few of these NOS valves were dropped off at the Pioneer Village recently, the donor called them steam valves. They look like a truck engine valve, 10.625" long, 2.5" head, .625" stem, the head and 4" of the stem appear to be stainless steel, the rest of the stem is steel with surface rust.

AFAIK which is not much when it comes to steam, steam valves are usually slide valves, if these are steam valves what type of steam machinery would they be used in? The Pioneer Village doesn't have a use for them.
