Smart SV04M 28-Channel Multiport Switching Valve (CAT#: STEM-AL-2607-ZJF)

The Smart SV04M is an electrically actuated multiport switching valve for controlled liquid routing. Its central valve-head port serves as a common inlet or outlet connected to multiple peripheral ports. The valve can direct mobile phases, reagents, buffers, or samples between different fluid paths. It is suitable for automated diagnostic, sequencing, and general fluid-handling configurations. Multiple valve-head options support systems with different channel counts and internal flow-path sizes. The wetted path uses alumina ceramic to provide a stable contact surface for process liquids. External controllers can operate the valve through serial communication and supported command protocols. The compact module is designed for integration into instrument fluidic assemblies requiring repeatable port selection.
