Precision Medical ceramic valve plates

Medical ceramic valves are key components in medical equipment, mainly used for fluid control systems in medical equipment. Valve plate refers to the seal, plate or spool in the valve, which is the key part to precisely control the flow of medium in the pipeline, cut off or regulate the flow. The valve plate prepared by ceramic material has excellent corrosion resistance and chemical stability and wear resistance, which can meet various special needs.
The surface finish of ceramic valves can reach Ra 0.03 and flatness can reach 0.001mm.

Step 1 Type of material

The materials of ceramic valve discs mainly include alumina, zirconia, silicon nitride and composite materials, etc., which need to be selected according to the load characteristics, environmental atmosphere and other comprehensive conditions.

Alumina ：Alumina has high hardness, excellent corrosion resistance and cost-effectiveness, and is currently the most widely used material.
Zirconia ：Zirconia has a low coefficient of friction and very good self-lubricating properties, which can effectively prevent impact fracture and is suitable for application scenarios with high requirements for impact and finish.
Composite materials ：Alumina reinforced zirconia (ATZ), zirconia toughened alumina (ZTA) and other composite materials, in the original performance of the base material on the basis of the performance of the material can be introduced into the performance of the characteristics of the added material, to obtain both wear resistance and toughness at the same time a new performance.

Step 2 Product Features

Excellent corrosion resistance: able to resist the erosion of various physiological fluids, disinfectant reagents and corrosive drugs, extremely stable chemical properties
High hardness and wear resistance: Rockwell hardness up to HRC90, wear resistance is twice or even tens of times that of ordinary metal valves. It is several times or even dozens of times of ordinary metal valves.
Good biocompatibility: no adverse reaction when contacting with human tissues and body fluids, suitable for implantable medical devices.
High-precision Control High precision control: high surface finish Ra0.03, flatness 0.001mm, can realize precise flow control and sealing performance.

Step 3 Application Field

Medical industry

Ventilator equipment: used to accurately control gas flow and pressure, to ensure the stable operation of the ventilator
Infusion pumps and syringe pumps: to improve the service life of the equipment and the accuracy of flow control, to provide protection for clinical treatment.
Hemodialysis equipment: to control the flow and pressure of dialysis fluid, and at the same time resistant to chemical cleaning agents and disinfectants
In-vitro diagnostic equipment: excellent in devices that require frequent contact with corrosive media or disinfectants.

Semiconductor industry

Ceramic valve plate, can be used for high-purity media (such as semiconductor ultrapure water) and other delivery systems, ceramic valve plate of non-polluting, inert characteristics can ensure the cleanliness of the fluid.
