Abstract: A unitized, rubber coated valve body for a dry barrel fire hydrant. The valve body is formed to have a hollow, tapered, substantially spherical, cast iron member having a hollow center, a threaded, upwardly facing hole for attachment to a control shaft or stem, a downwardly facing projection, and a rubber coating. The unitized body eliminates labor of assembly during service and maintenance operations. The rubber coating both provides a resilient valve face for effective sealing, and protects metal parts of the valve from corrosion arising from contact with water. The tapered body both distributes force evenly to the rubber valve face in the manner of a prior art metal disc, and enables water to flow therearound with minimized resistance, thereby maintaining head pressure at acceptable levels. The novel valve body satisfies both objectives while minimizing weight and requiring minimal material for fabrication. The body is formed with integral ears for slidably obstructing drain holes.
