The new ZEDOX double-offset, metalling sealing high performance valve, together with the triple-offset process valve ZETRIX, and the eco-centric butterfly valves ZESA, GESA and ZIVA, enables ARI-Armaturen to provide a more comprehensive butterfly valve portfolio.
In contrast to centric butterfly valves, the double-offset sealing principle of ZEDOX reduces the angle of the disc when entering into contact with the seat sealing ring, relieving the metallic sealing when opening.
It offers higher energy efficiency and longer service life due to reduced contact pressure and minimised friction, protecting the seat sealing ring against negative flow influences.
ZEDOX is tight at temperatures from -40°C up to +260°C (max. +400°C with specially designed models), for pressure classes PN 10 to PN 40 plus ANSI Class 150.
ZEDOX is made in either cast carbon steel or cast stainless steel. Different versions/materials are available upon request.
