Abstract
A downhole valve apparatus, for controlling fluid flow in drilling operations, includes a tubular housing and a float valve movably held within a valve bore of the tubular housing and partially within a stress relief bore. The float valve is axially movable relative to the tubular housing while in a sealing relationship with the valve bore between a first configuration and a second configuration of the downhole valve apparatus. A valve member of the float valve allows a downward flow of a drilling fluid of a first pressure to flow through the float valve in the first configuration, and the valve member blocks an upward flow of any fluid of a second pressure from the well through the float valve in the second configuration.
