Poultery drinking system pressure regulator OPTIMA

The OPTIMA level valve is designed to supply a constant amount of water to longitudinal drinkers. The best alternative to the unreliability of traditional "buoy" or float taps. Simple adjustment of the water level, according to the distance to the feeder/drinker. It works with any previous pressure between 0, 5 and 5 bar. How does it work? When the water level reaches the bottom of the rigid tube, air cannot enter it. This causes a vacuum that swells the inner membrane, which in turn causes the closure of the water passage. The water level is set by adjusting the distance between the lower end of the tube and the bottom of the drinker.
