Abstract
An in-line valve assembly for a tubular drag conveyer system includes a first tube segment having a first end and defining a first passageway, a second tube segment having a second end and defining a second passageway, and a tubular valve body translatably disposed relative to the second tube segment and defining a valve passageway. The first end of the first tube segment is spaced apart from the second end of the second tube segment by a gap. The valve body is selectively adjustable between a closed position wherein the valve passageway spans the gap and connects the first passageway to the second passageway and an open position wherein the valve passageway is spaced apart from the first passageway by at least a portion of the gap.
