Abstract

Fluid flow control members for use with valves are described. An example poppet apparatus for use with an internal valve includes first and second opposing seating surfaces to control fluid flow through the internal valve. Additionally, the example poppet apparatus includes an aperture to receive a stem of the internal valve. Further, the example poppet apparatus includes a flow diverter to divert fluid flow through the poppet apparatus to substantially prevent the fluid flow from compressing a spring to be at least partially positioned in the poppet apparatus.
