The newly developed and patented filling valves are made of 304 stainless steel

opening of the valve during filling is electronically controlled by a PLC, pre-evacuation, double pre-evacuation; pre-injection, valve opening; self-levelling and degassing are controlled by electro-pneumatic valves controlled by a PLC.

Elimination of all timing adjustments, even in the event of complete disassembly of the valve, to simplify maintenance operations;
Elimination of the mechanical height adjustment of the control support rims, normally found in mobile head machines, with consequent reduction in the time required for format change; degassing times parametrised by a Touch Screen managed by an operator with the possibility of processing recipes according to the difficulties of the product treated. 
circuit sanitisation and sterilisation is carried out simultaneously on all the valves with the machine stopped, all circuits are washed and sanitised in counterflow.

Moreover, Alfatek valves can also fill without pressure in the tanks and therefore by gravity or with low pressure, with considerable advantage in the case of filling still wines.
