SV07M 28-Channel Multiport Switching Valve (CAT#: STEM-AL-2608-ZJF)

The SV07M is an electrically controlled multiport valve for selecting among multiple liquid pathways. A central common port connects with a series of peripheral ports through the rotating valve head. This arrangement allows one inlet or outlet to communicate with different reagents, buffers, mobile phases, or samples. The valve can be integrated into diagnostic, sequencing, and automated fluid-transfer systems. Several channel configurations and flow-path diameters are available to match different routing requirements. Alumina ceramic forms the wetted valve components and supports controlled liquid contact. RS232 and RS485 interfaces permit operation from an external controller, while CAN communication can be customized. The higher-drive actuator supports repeatable switching in compact analytical instrument assemblies.
