摘要 <p>A novel double block and double bleed stream switching system includes a common stream path for a multitude of fluid streams from, for example, a process pipeline. The common stream path includes a blocking port and a blee d port, and connects to at least one sample shut off. Preferably, the common stream path and sample shut off are shallow channels machined in a multi- layered block, with integrated pistons (450-457) and ports (311-366, 332, 33 3) controlling the flow from each stream and through the stream switching syste m.</p>
