These automatic flow-through valves regulate flow between 1 and 6 BAR.
The black one has a constant flow rate of 0.5 ltr/h
The blue one has a constant flow rate of 1 ltr/h.
So you no longer need a reducing valve and have high pressure all the way to the drinking nipple.
The water runs out dosed without spraying.
