ABSTRACT:
A body having a longitudinal axis, and parallel bearing surfaces at opposite axial ends thereof, has grooves formed therein, adjacent both axial ends thereof for receiving sealing rings therein. The body is interposed between fluid-control valves which are centrally supported, in spaced-apart disposition on a reciprocable rod, for abutting engagement thereof with the outermost peripheries of axial ends of the valves to support the valves and prevent bending moments from being exerted on the valves, and the grooves-receivable sealing rings offer enhanced fluid sealing over that carried by the valves themselves.
