Alfatek self-levelling filling valves represent the most innovative aspect of the hyperbaric filler (low pressure), allowing precise and repetitive levels, without the need for a vacuum in the filling tank.
Thanks to the tubes for evacuating the air from the bottle, present on the outside of the valve, and to the separation partition inside the tank, it is possible to convey the air extracted from the bottles outside the filling tank, avoiding microbiological pollution and contact between the oxygen and the product.
The absence of the air return tubes inside the tank facilitates washing and sterilisation and allows evacuation of the air from the bottles.
The filling valves can be equipped with automatic level variation, thus allowing the simultaneous variation of the levels on all the valves from the control panel (0-80 mm), or with default programming via PLC; possibility of having two systems:

• Valve with electro-pneumatic level adjustment.
• Mechanical level adjustment valve with continuous adjustment while machine is filling.
