Abstract

A valve assembly for a filling machine has an adduction conduit along a valve axis connectable to a tank to allow inflow of liquid from the tank to containers. A shutter inside the adduction conduit moves between a closing position and one or more opening positions. A tubular control stem internally defines a conduit. A probe for detecting filling level with a single detection point near the probe tip is inserted inside the conduit defined by the tubular control stem and moves between at least one extracted position and a retracted position. A first electric motor connected to the tubular control stem moves the shutter between the closing position and the one or more opening positions. A second electric motor connected to the probe moves the probe between the at least one extracted position and the retracted position. The first and second electric motors are controllable independently from each other.
