SV07B 1.2 mm Electric Injection Valve (CAT#: STEM-AL-2612-ZJF)

The SV07B is an electric injection valve that switches dynamically between two fluid pathways. Its two-position multiport structure is designed for use with an external sample loop. The valve supports automated sample loading and transfer within analytical fluidic systems. Six-port and eight-port valve-head configurations are available. Both versions use a 1.2 mm flow path and alumina ceramic wetted components. The actuator provides greater drive capacity than the lower-torque configuration while retaining the same routing concept. RS232 and RS485 communication interfaces enable connection to an external controller. Supported command protocols simplify integration into automated sampling and injection modules.
