6712 2/2-Way Whisper Valve

Brand: Burkert Fluid Control Systems
Does not ship to OH, United States

Fluidical "point-of-care" applications, as dialysis or artificial respiration, and applications at the "point-of-use" for example at pipetting arms in biological analysis have special requirements. The new media separated Whisper Valve type 6712 was particularly developed for these applications. Especially the reduced switching noise and the good flush ability set a new benchmark. 

But also in industrial applications like inkjet printers, the type 6712 is the first choice due to the high lifecycle and the excellent switching dynamic. With the modular design and the available material variants this valve is applicable with virtually all liquids and gases in life science and industrial applications. 

A valve that combines dosing accuracy and flush ability.
Features
  • Highest chemical resistance with minimal internal volume
  • Compact design with 0.27" (7 mm) width
  • Switching noise < 36 dB
  • For dosing applications with excellent flush ability
