-21- ABSTRACT OF THE DISCLOSURE A valve element is disclosed comprised of a body section, upper guide, lower guide, sealing section and reinforcement section. The reinforcement section is made of materials having a hardness greater than the lower guide and sealing section. The reinforcement section, as well as the sealing section, have a frustoconical outer surface to increase support of the sealing section due to bracing from a mating valve seat annular sealing surface. The frustoconical outer surfaces of the valve element combine to form a uniform frustoconical surface. Two sealing sections may be disposed above and below the reinforcement section. These two sealing sections have frustoconical outer surfaces that cooperate with the frustoconical surface of the reinforcement section to form a continuous, co-extensive frustoconical outer surface.
