The gravity filling machine can operate by simple gravity and, if the type of container permits, also with a slight depression in the tank which in some cases helps trigger the actual filling phase.
This type of machine is suitable for all so-called flat products, without co2 and not dense. Among these are water, spirits, wine, vinegar and many more.
For the gravity or slight vacuum filling machine, fimer manufactures various types of valves, each with features that make them more appropriate for the various products and, in terms of shape and material, for the container to be used.
