Eltek Water Block Overflow Safety Device

The Water Block valve is an overflow safety device, which controls the maximum potential leaking of water between 5 and 50 litres. Its function is to measure the number of litres of water that have passed through it. If this quantity exceeds the set value, the Water Block stops the flow and keeps this safety condition until re-set by the user. If the water volume does not exceed the set value, the Water Block mechanically and automatically resets the measured volume and the Water block is ready to restart a new measurement cycle. The Water Block does not require external energy, simply water to flow through it.
