Bürkert 2/2 or 3/2-WAY Whisper Valve with Media Separation

Many fluidic processes moving closer to where they are actually required. In medical technology, this means, for example, that treatments such as dialysis can be carried out in a comfortable, home-like environment for the patient. In analytical instruments, washing units are mounted directly on the pipetting arm, and in inkjet printers, valves are located directly on the print head. These applications place high requirements on the components used: solenoid valves must operate almost silently and be compact and lightweight so that they can be integrated into mobile devices. At the same time, a long service life and excellent switching performance are crucial. The Whisper Valve Type 6724 meets all these criteria. Thanks to its modular design and range of material options, it can be used universally in a wide variety of applications. Thanks to the ValveInsight functionality, the valve offers intelligent monitoring and diagnostic capabilities. Thanks to ValveInsight algorithms, which analyse valve data in real time, valves are evolving into smart components that detect anomalies at an early stage and significantly improve process reliability.
