ZS20-02 Mini Selection Valve

The zs20-02 MINI Selection Valve is a miniaturized multi‑channel flow‑path selection component designed for limited installation space and matched with high‑precision industrial syringe pumps. Compact in size, it realizes automatic switching of multiple pipelines for processes including multi‑reagent aspiration, sample selection and waste liquid discharge. Its wetted parts are made of corrosion‑resistant ceramic. The flow channels have low dead volume to effectively reduce sample cross‑contamination. A built‑in miniature motor drives precise commutation, enabling automatic program control with a host computer or PLC. Featuring streamlined construction and small footprint for easy embedded integration, it is suitable for portable analytical instruments, miniature microfluidic systems, compact on‑line monitoring devices and mini micro‑dosing units. It delivers multi‑channel fluid distribution and automatic switching within a tiny installation dimension.The Selection Valve MINI is a compact miniature multi‑channel flow‑path selection component. With small size, low dead volume and corrosion‑resistant ceramic wetted parts, it supports automatic programmable control and fits small‑sized instruments and microfluidic systems.
