The zirconia ceramic valve core and sleeve for pharmaceutical metering pumps are manufactured from high-purity ZrO₂, offering excellent wear resistance, corrosion resistance, and non-magnetic properties. Designed for high-precision fluid dosing and filling applications, these ceramic components ensure stable flow control, accurate metering, and reliable sealing performance.
With ultra-smooth polished surfaces and tight dimensional tolerances, the valve core and sleeve operate smoothly under continuous working conditions, minimizing leakage and wear. They are ideal for pharmaceutical, medical, and clean fluid handling systems where precision, durability, and chemical stability are critical.
High Wear Resistance – Excellent hardness ensures long service life under repeated valve operation and high-frequency dosing.
Corrosion Resistance – Stable performance in contact with aggressive chemicals and pharmaceutical fluids.
Non-Magnetic Properties – Suitable for medical, pharmaceutical, and sensitive equipment applications.
Superior Sealing Performance – Precision-matched valve core and sleeve reduce leakage and ensure accurate dosing.
High Surface Quality – Polished surfaces (Ra ≤0.2 μm) minimize friction and particle generation.
Precision Dimensional Control – Tight tolerances on critical mating surfaces ensure consistent performance and interchangeability.
