Volumetric gravity filling monoblock for large size containers in PET

Bigfill is an electronic rotary volumetric filler for bottling still liquid products in large PET bottles. The machine is optimized for moving and filling large formats (up to 20 litres)


  • No contact between valve and bottle.
  • High flow performance and filling speed modulation to optimize the large size filling process.
  • High bottled product precision
  • Extremely clean and simple filling valve.
  • Automatically engaged dummy bottles.
  • Valves made entirely of AISI 316 stainless steel.

Electronic volumetric gravity filler for big size bottles

Bigfill (mass flowmeter)

Electronic volumetric gravity filler for big size bottles, with mass flowmeter for low conductivity products

Process phases : main features and advantages

  • External tank
  • Valve with magnetic flow meter for definition of the content in the bottle.
  • Designed for filling large formats (up to 20 litres).
  • No filling tube.
  • During filling, the bottle is kept in position by a mechanical gripper.
  • Inside the monoblock, the full bottles of over 5 lt are moved by the bottom.
  • Simple to operate with selection of the various formats directly from the operator panel.
  • Controlled contamination cabin and cap sterilizing unit available in option in order to enhance hygienic standards.
  • It can be produced with microbiological isolators, thereby minimising the filling environment around the container.

  • Extremely clean filling: no contact between valve and bottle.
  • High filling speed.
  • High bottle product precision.
  • The air in the bottle does not come into contact with the product feeding circuit.
  • Automatically engaged dummy bottles.
  • All parts in contact with the product are made of AISI 316L steel.
  • Simplified access for maintenance of the motor and the manifold
  • Latest generation of electronic/pneumatic components, managed by an industrial PC.

  • Double filling speed with final slow speed phase is obtained by means of a 3-position actuator
  • No contact electronic valve with volumetric filling controlled by a magnetic flow meter.
  • Thefinal slow phase allows the foam to collapse before closing
  • The version with mass flow meter, ideal for viscous or low conductivity products, such as edible oil, deminaralised water, etc
  • The nozzle with wide pass-through sections was designed to obtain the highest flow through the bottle neck and to minimize the turbulence of the product

  • Extreme sanitizability is one of the most important elements of this valve, characterized by a limited number of components and of moving parts.
  • The sanitation phase is very simple and is managed fully automatically through a control on the communication keyboard: the cycle is carried out in such a way that the solution laps against all the internal areas of the filler with forced flows.
  • The dummy bottles are loaded automatically.
  • Circuit preset for CIP and SIP up to 100 °C.


The filler is designed for PET bottles filling.
