    Default OT poppet steam valves

    A few of these NOS valves were dropped off at the Pioneer Village recently, the donor called them "steam valves". They look like a large IC 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.

    I doubt they would be out of a truck, possibly a very large stationary engine.
    They would make very good punches, if nothing else.

    They look very similar to valves used in Diesel/Electric Locomotive Engines I used to work on some thirty years ago - ALCO, GE and GM-EMD. So some largish Diesel Engine would be my guess, brand unknown unless there are ID marks or other details. The head of the valve will be some type of Stainless Steel and the Stem will be a Carbon Steel, bonded together by some means now forgotten by me. Often the Valve Seats were Stellite for good life.

    Steam engines can depending on their design can have not only slide valves, but piston valves (inside or outside admission), rotary valve (Corliss valve engine where the valve rotates) or a poppet valve (eg Sentinal Steam truck).

    As the steam cylinder gets bigger so does the valve(s). I am not able to say that this is or is not from a steam engine. It is possible that it is from a make like Ruston Hornsby that made steam engines before going to internal combustion engines.

    Would friction welding work for something like this? Or do the pieces have to be the same material?

    Hi Guys,

    I thought that those valves could have come from a large, probably, diesel engine.

    Re friction welding: That technique has been used to weld all sorts of metals to each other.
