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.
