Abstract
In an exemplary embodiment, an apparatus includes a valve assembly, the valve assembly including a tubular member and a valve connected thereto, wherein the valve permits fluid flow through the tubular member in a first direction and prevents fluid flow through the tubular member in a second direction that is opposite the first direction. A plug is adapted to be secured to the valve assembly so that the plug is prevented from moving, relative to the valve assembly, in the first and second directions. In an exemplary embodiment, the apparatus is a cementing plug apparatus, which can plug a tubular string or casing so that fluid flow therethrough is prevented. In an exemplary embodiment, the tubular string or casing may be positioned within a preexisting structure such as, for example, a wellbore.
