Offered for sale is an authentic antique cast‑iron plug valve / standpipe valve assembly, manufactured by AV & Co. (American Valve Co.) of Boston, Massachusetts, dating to approximately 1890–1920.
This is a heavy, solid cast‑iron inline valve with flanged ends, a side outlet, and an original rotary lever mechanism with curved travel‑stop plate—a classic feature of early plug valves used in farm, industrial, and municipal water systems.
