SV07M 3.0 mm Large-Bore Multiport Switching Valve (CAT#: STEM-AL-2609-ZJF)

The SV07M large-bore series is a multiport switching valve designed for fluid paths requiring larger internal diameters. Its valve head uses a central common port that can connect sequentially with multiple peripheral ports. The configuration enables controlled switching among mobile phases, reagents, buffers, and liquid samples. Available valve heads cover several channel counts and bore sizes for different system layouts. Larger internal passages provide increased rotor-groove and port-to-port volumes compared with the standard-bore version. Alumina ceramic is used throughout the wetted valve structure. The module accepts serial commands through RS232 or RS485 and can be adapted for CAN communication. It is intended for integration into automated fluid systems that require repeatable multi-source selection.
