Ceramic Valves

Ceramic Valves

Our ceramic valves are dead volume free rotary valves for system pressures of up to 30 bar. They can be constructed according to customer specifications.

Valve construction  

  • Ceramic rotor floating in a plastic housing.    
  • A special connection between the drive axle and rotor ensures that no forces other than the rotating movement and contact pressure are applied to these components.    
  • Basic unit made of a new plastic compound (tested with all conventional HPLC eluents)    
  • Excellent chemical and mechanical resistance due to the use of ceramic and a special plastic compound.   


  • 3-way valve, 120°    
  • 4-way sample injection valve    
  • 4-way switching valve    
  • 3-position selection valve
