Abstract: The invention relates to a method for controlling a modulating valve during a filling operation on a plurality of receptacles to fill them with a pourable product. The valve includes a shutter for closing or opening an outflow passage of the valve, designed to control the filling of receptacles. The method includes measuring the flowrate of the pourable product passing through the valve; measuring the position of the shutter along the axis; and controlling the position of the shutter as a function of the desired flowrate. The method also includes defining an initial table containing at least the flowrate and position values measured prior to a first filling during the same filling operation; and updating the table with flowrate and position values measured during fillings subsequent to the first filling during the same filling operation. The controlling step is carried out as a function of the table.

Abstract: A fluid-agitating tank assembly is disclosed. The tank assembly includes a tank filled with a fluid, and an agitator disposed in the tank so as to be at least partially immersed in the fluid and supported by the tank in a rotatable manner about an axis. The agitator includes a double helix disposed in an upper volume of the tank and adapted to act on the fluid to transform unidirectional rotation of the agitator about the axis into a bidirectional movement of the fluid in the tank towards bottom and top portions of the tank, and at least one rotary blade projecting transversally from the axis, disposed in a lower volume of the tank, and rotating about the axis to move the fluid towards at least one lateral outlet of the tank.

Abstract: A filling machine for filling containers with a pourable product, comprising: a product tank containing the pourable product and a first gas maintained at a first pressure value; at least one dosing tank containing a second gas; a first pressurizing device configured to selectively pressurize the second gas in the at least one dosing tank to a second pressure value, that is lower than the first pressure value; a controller configured to: set the second valve in an open configuration after the at least one dosing tank has been pressurized to the second pressure value; and set the second valve in the closed configuration as the pressure detected by the sensor in the at least one dosing tank reaches a third pressure value corresponding to a predetermined volume of the pourable product in the dosing tank.

Abstract: A filling system for filling a container with a pourable product, comprising: a tank configured to be filled with the pourable product; at least one filling device including a local control unit having a control module configured to selectively allow filling of the container with the pourable product; at least one duct interposed between the tank and the filling device; and at least one vortex flowmeter disposed along the duct and configured to generate a pulse-train detection signal as a function of a flow rate of the pourable product along the duct, wherein the local control unit of the filling device includes a processing module configured to process the detection signal from the at least one vortex flowmeter in order to determine an amount of the pourable product flowing into the container, as a function of a number of pulses of the detection signal.

Abstract: A valve is disclosed. The valve has a magnetic actuator, which is provided with a sleeve extending along an axis, with a movable core made of ferromagnetic material and axially guided by the inner surface of the sleeve, and with a magnetic stator arranged in a fixed position around the sleeve. The stator has a housing made of ferromagnetic material, a coil facing the external surface of the sleeve, and two magnets, which are aligned with the coil, are arranged on opposite axial sides of the coil, and have a same pole aimed against each other. The valve has a conduit with a valve seat axially facing a plug member, which is coaxial and fixed with respect to an end portion of the core, so as to open and close the valve seat. The core has at least one passage allowing a fluid to flow through the core.

Abstract: A filling machine for filling a container with a liquid having a gas line, a liquid supply line connectable to a liquid tank and at least one filling device. The filling device having an inlet communicating with the liquid supply line, a lower outlet and a gas port communicating with the gas line. A differential pressure sensor is connected to the gas line and the liquid supply line to determine a feedback value defined by the pressure difference between the lines. The gas line communicates with a gas tank that is separated from the liquid supply line and connected to a pressurized gas source. The gas tank is also connected to a discharge opening via valves controlled by an electronic control unit that brings the pressure difference between the liquid supply line and the gas line to a set-point corresponding to the feedback value.
