Smart SV04B 1.2 mm Electric Injection Valve (CAT#: STEM-AL-2611-ZJF)

The Smart SV04B is an electric injection valve for dynamic switching between two liquid paths. It uses a two-position multiport arrangement and is intended to operate with a sample loop. The valve-head configuration supports automated loading and injection sequences in analytical fluid systems. Six-port and eight-port variants are available with the same internal flow-path diameter. Alumina ceramic is used for the wetted valve components. The actuator can be controlled through RS232 or RS485 serial communication. Custom, ASCII, and Modbus protocols allow integration with different host-controller architectures. The compact assembly is suitable for instrument designs requiring repeatable sample-path selection.
