Electric rotary valves

Stepper motor driven. For sample collection, loop injection and flow selection applications


Bio-Chem Fluidics electric rotary valves are available in two general configurations: valve head assembly complete with stepper motor or just the valve head assembly. Both versions are fitted with an encoder. Whereas endusers commonly decide on the complete solution, instrument manufacturers with experience of coupling valves to stepper motors and with their own controllers often prefer the valve-head-only option. The valves come in three bore sizes and for two application areas: loop injection and flow selection/distribution. All models have a very low internal volume and are designed for use in low-pressure applications only.

 

  • inert flowpath
  • 1/4"-28 UNF flat-bottom ports with stainless steel inserts
  • 2-channel optoelectronic position sensor and optical encoder disc
  • mounting dimensions fit NEMA 17 stepper motor

For models with NEMA 17 motor:

  • 1.8° step angle
  • port-to-port movement time 250 ms
  • life of assembly up to 1,000,000 port-to-port cyles
  • recommended max. duty cycle 12.5%
  • 4-wire connection
  • Neodymium magnets for maximum torque
