Between the days 9^th  and 13^th  of November the EIMA INTERNATIONAL fair took place in the city of Bologna (Italy) in which the main international brands of the water industry met. EIMA INTERNATIONAL is an essential event for the members of the industry: farmers, technicians, researchers … HIDROTEN took part again as an exhibitor, with its regular stand, in which some of its novelties were shown as well as the extension of its range of products. Among its novelties, the one which stood out the most was the BUTTERFLY VALVE PPR Ø400.  We want to highlight the great interest that visitors showed on the wide range of Net® Air release valves (Family 17), Vacuum valves (Family 14) and the Compact valves (Family 11C).
