The Alumina Ceramic Blood Separation / Diverter Valve is a precision fluid-control component made from high-purity alumina for hematology analyzers, in vitro diagnostic (IVD) systems, blood-processing equipment, and medical analytical instruments. Precision-machined micro-holes, flow grooves, and mating surfaces enable controlled switching and distribution of blood samples, reagents, and cleaning fluids while supporting wear resistance, dimensional stability, and reliable operation during repeated fluid-control cycles.
This ceramic valve is primarily manufactured from 99.5%–99.9% high-purity alumina (Al₂O₃). High-purity alumina is selected for its high hardness, dimensional stability, chemical resistance, and suitability for precision grinding and polishing.
The appropriate alumina grade can be selected according to the fluid medium, operating frequency, mating structure, surface requirements, cleaning conditions, and requirements of the final equipment.
