Alumina ceramic valve body

Alumina ceramic valve bodies, as high-precision components for medical machinery, possess the following core characteristics and technical features:

Ⅰ. Material Properties

1. High Hardness and Wear Resistance: Alumina ceramic has a Rockwell hardness of HRC90, second only to diamond, and its wear life is 2-4 times longer than that of metal valve bodies, making it suitable for frequent opening and closing applications.

2. Corrosion Resistance: It can withstand strong acids, strong bases, and strong corrosive media except hydrofluoric acid, meeting the requirements of medical equipment for cleanliness and chemical stability.

3. Precision Machining Performance: The surface finish of the flow channel holes is high, and the parallelism can reach 0.05mm, achieving zero leakage through self-lubricating lapping technology.

Ⅱ.Structural Design

1. Four-Way Rotary Valve Function:  Utilizes an X-type or LL'-type flow channel structure, achieving multi-channel fluid switching through 90° rotation, replacing traditional multi-valve assemblies to save space.

2. Flow Channel Optimization: The flow channel design reduces media residue and is polished to a roughness of Ra≤0.4μm, meeting the dead-space-free cleaning requirements of medical equipment.

3. Sealing Technology: The ceramic self-lubricating sealing structure is suitable for high-temperature and high-pressure conditions, and some models support metal/PTFE composite seals to enhance reliability.

Ⅲ.Suitability for Medical Applications

1. Biocompatibility: Alumina ceramic is FDA-approved and suitable for medical applications such as sterile solution preparation and ventilators.

2. Operational Flexibility: Supports electric drive (AC220V/380V or DC24V) and manual emergency operation, compatible with automated control systems.

3. Easy Maintenance: Modular design allows for segmented replacement of valve cores or seals, reducing downtime and maintenance costs.

Ⅳ.Application Scenarios

1. Precision infusion systems: Controlling drug solution diversion with flow rate regulation accuracy of ±1%.

2. Dialysis equipment: Corrosion resistance ensures safety during long-term contact with dialysis fluid.

3. Ventilator gas control: Fast response to airflow switching, with a sealing lifespan exceeding 150,000 cycles.

Supports custom specifications.
