Nothing more than a rustle
NORMA-PLUS is the extra silent float valve designed and manufactured by Kariba®. Thanks to the patented Kariball technology, which exploits the mechanical potential of a sphere and the physical characteristics of water, NORMA-PLUS is an extremely silent solution. The action of the sphere grooves, together with the filter, favor the "diffusion" effect of the water, drastically reducing its noise. NORMA-PLUS is approved in acoustic class 1 by the prestigious German organization LGA – TUV.
Operating mechanically, NORMA-PLUS overcomes any maximum and minimum pressure peaks and ensures better efficiency even when there is residue in the system. Like all Kariba products, NORMA-PLUS float valve is 100% Made in Italy, and each component is tested in the production line at a minimum of 12 bar.
