ABSTRACT:
The specification discloses a fire hydrant and valve assembly therefor including a flexible, resilient compressible, fluid-impervious sealing flange or lip formed on and extending outwardly of the main valve sealing member for supplemental sealing of both the water passageway through the main valve seat ring and between the valve seat ring and inner surface of the hydrant conduit.
Also disclosed is a method for assembling a valve assembly in a fire hydrant to prevent damage to the valve assembly by using the sealing flange or lip on the sealing member to locate and guide the valve assembly through the valve seat area of the conduit as well as to lubricate that area during insertion of the valve to ease assembly and facilitate later disassembly.
