High Purity Alumina Ceramic Rotors Stators for Switching Valve Systems

Key words : Ceramic Rotors Stators

High-quality ceramic rotors and stators (aluminum oxide Al2O3 99.9%, 99.7% and 96% and zirconia ZrO2) are present in low and high pressure injection valves. These components are equally vital in any other switching valve systems where inert materials resistant to the harshest solvents are required.

Mingrui manufactures high quality Rotors and Stators, made out of High Purity Alumina (96%, 99,7% or 99,9%) and TZP Zirconia ceramics for high and low pressure injection and selection valves. Rotors and Stators are subject to intensive mechanical stress and chemical aggression while having to maintain a perfectly leak free adjustment between the two components. No leak, limited stiction and low wear are the most important parameters to guarantee long life and reliability to your valve. These can be achieved by an adequate surface finish, a perfect flatness of the surfaces in contact and a proper selection of the material. Every application is different and Ceramaret will help you define the parameters required for your particular valve. Ceramic Rotors and Stators are used in valves for many high-tech applications, such as HPLC, micro-HPLC, Medical, Industrial, etc.

Typical Characteristics Rotor: Outside diameter: < 30,00 mm ( 1.18") Thickness: < 7,00 mm ( . 28") Groove(s) dimensions: Width > 0,051 mm ( .0002") Depth > 0,13 mm ( .0052") Length > 2,00 mm ( .0780") Stator: Outside diameter: < 30,00 mm ( 1.18") Thickness: < 7,00 mm ( . 28") Hole diameter: > 0,22 mm x 0,25 mm (.008" x .010") Surface finish, Rotor or Stator Zirconia:  0,025 m (1 in) or N1 Alumina 99,9 %:  0,05 m (2 in) or N2 Alumina 96% or 99,7%:  0,1 to 0,2 m (4 to 8 in) or N3 to N4

Advantages of Ceramic Split Bushes:

1. Isostatic pressed.
2. Fire resistance.

3. Superior mechnical strength.
4. High corrosion and wear resistance.
5. High Temperature Resistance.
6. Good Insulation Performance Precision.
7. Zirconia and alumina ceramic material.

They are high corrosion and wear resistance and strong impact resistance and delivers 10 times longer working life than metal plunger. They give a longer life to the sealed packing material.
