Electric rotary or selector valve is a stepper motor driven fluid handling valve designed for fluid selection and distribution and automated fluidics injection  applications.  The precise rotary valve provides automated routing of fluidic volumes for aggressive  or reactive fluids. The inert path is achieved by aligning holes in a PCTFE rotor with holes in the valve body.  There is an optical encoder inside the valve to provide accurate information of the position of the rotor.  Users can easily program the valve controller to perform desired position sequence via the communication interface.  


Key Features

  • No metal parts contact with working fluid;
  • Wet materials: PCTFE valve head, sapphire valve spool for anti-corrosion; 
  • Manufactured with smooth internal flow path for easy flushing and cleaning;
  • 1.2 mm orifice size and 8 ports configuration;
  • Minimal dead volume of 5.14 µL; 
  • Avoid cross-contamination;  
  • Excellent sealing surface design to maintain consistent torque in a specified range;
  • Highly reliable valves  guaranteed by precisely machined and polished assembly process; 
  • Optical encoder for accurate positioning;
  • Communication interface: RS232/RS485/CAN;  
  • Rotary valve customization is available
