<p>A valve assembly connectable between first and second downhole components that each have first and second internal flowpaths. The valve assembly comprises a first valve operable to selectively fluidly couple the first internal flowpaths of the first and second downhole components, as well as a second valve operable to selectively fluidly couple the second internal flowpaths of the first and second downhole components.</p> |
