The shell has an exterior surface, an interior surface, and two opposing annular openings. The valve member further includes a sleeve having a first end and a second end. The sleeve is positioned between the annular openings of the shell to define a central bore between the annular passages. The sleeve is in contact with and fixed to the shell solely at the first end and the second end thereof in a way that a continuous void is defined between the sleeve and the interior surface of the shell from the first end of sleeve to the second end of the sleeve.
