2/2-way Whisper Valve with media separation
Type 6712 / Article No. 273206
Product description
Fluidic “point-of-care” applications, such as dialysis or artificial respiration, and “point-of-use” applications, such as at pipetting arms in biological analysis, present special requirements. The new, media-separated Whisper Valve Type 6712 was developed for precisely these applications. It sets new benchmarks particularly with low switching noise and excellent cleanability. However, the Type 6712 is also the first choice in industrial applications, such as inkjet printers, thanks to its long service life and excellent switching dynamics. The valve’s modular design and available material variants means that it can be used with practically all liquids and gases in the fields of life sciences and industrial applications. This is a valve that combines dosing accuracy and cleanability.
