It features a unique coupling that extends into the main stream of flow, allowing live samples to be extracted. When the valve is closed, the piston fills the valve body and extends flush to the end of the coupling, eliminating dead space and preventing clogs. When open, the piston is retracted into the body allowing a free-flowing sample. An opening indicator shows the position of the piston for product flow anticipation.
