What is a jet valve?

A jet valve is the essential component for the contactless dispensing process. Thanks to the sophisticated nozzle geometries and the precise control of the valve smallest droplets can be applied contactless. The tappet is opening and closing with high frequency and thus pushes the dispensing medium through the nozzle. The medium is supplied at constant air pressure. This produces an impulse at the nozzle which leads to an extremely fast acceleration of the outgoing dispensing material so that the liquid is applied directly on the substrate and not deviated in different directions.
