6724 2/2 & 3/2-Way Whisper Valve

Brand: Burkert Fluid Control Systems

Many fluidic processes come closer to the point of interest. For example medical devices like dialysis machines become homecare devices and operate close to the patient. Washing units in analytical equipment are positioned on the pipetting arm or directly on the print head in printing applications. This requires special components. 

Solenoid valves need to switch without noise. They need to be smaller and lighter. 

Nevertheless it is essential to guarantee a long lifetime and excellent switching characteristics. All this is concerted in the Whisper Valve type 6724 and thanks to the modular structure and the range of available materials this valve is almost universal.
