The Water Block valve is a safety overflow device which controls the flow of a volume of water between 5
and 50 litres.
Its function is to measure the number of litres of water that have passed through and, if this quantity exceeds that for
which it was set, the Water Block intervenes and stops the flow.
The Water Block does not require external energy as it is operated by the water flowing through it.
