The Net® suction aeration valves are made entirely of plastic materials, PVPP or PA PA for the body and for the base. To suit each use, the range consists of three types of suckers: Kinetics, single and double acting or Trifunctional; aimed at eliminating the air generated by driving itself, and allows the air inlet to avoid collapses on site.
