The PressMatic bacteria-free line urinal valve was designed for public environments with high circulation of people, since it has a highly durable internal cartridge for environments with continuous use and a highly resistant and hygienic chrome finish due to Bacteria-Free technology where chrome receives silver nanoparticles, which make the metals antibacterial, eliminating 99% of bacteria from the product. The valve also has a hydromechanical drive, which guarantees automatic closing in approximately 6 seconds, ensuring water savings and preventing the product from remaining open without the need for use.
