Z20-02Z Multi‑channel Selection Valve

The Z20-02Z multi‑channel selection valve is an automatic flow‑path switching component used together with high‑precision industrial syringe pumps. It enables automatic switching among multiple pipelines to perform processes such as multi‑reagent aspiration, sample selection and waste liquid discharge. The wetted parts of the valve are made of corrosion‑resistant ceramic and other materials. The flow channels feature small dead volume to reduce cross‑contamination. Adopting motor‑driven automatic commutation, it supports program control via a host computer or PLC. With a compact structure for easy embedded integration, it is widely applied in analytical instruments, microfluidic systems, on‑line monitoring and precision micro‑dosing equipment, allowing a single syringe pump to achieve multi‑channel fluid distribution and switching.

Product Details:

Core technology

  1. Ceramic valve core: corrosion-resistant, self-lubricating, suitable for a variety of special media;
  2. Drive integration: the valve body motor control circuit is integrated inside, and the host can communicate with the controller through the RS485 protocol;
  3. Resistance to strong chemical corrosion: only the valve body and valve core are in contact with the medium, and the valve body is made of special fluoroplastics, which can be applied to various corrosive liquids;
  4. Wide selection: 6 to 32port switching valves with various port positions are optional;
  5. Sealing method: the stator and the rotor are closely fitted to achieve the highest service life and excellent sealing;
  6. Drive mode: motor direct drive, more accurate positioning and higher precision;
  7. Fully closed-loop control is adopted to ensure the reversing and positioning accuracy of the liquid circuit;
  8. Accurate position feedback, the feedback position information is calculated by the encoder;
  9. Stall information feedback;
  10. Provide convenient configuration software tools to facilitate parameter configuration and debugging;
