ZEDOX® – The new high performance valve

ARI-Armaturen is delighted to introduce a double-offset, metallic sealing high performance valve – ZEDOX®. A durable, energy-efficient valve with perfect handling, it represents the economic alternative along with reliable tightness for high requirement applications. Together with the successfully established triple-offset process valve ZETRIX® and the standard butterfly valves ZESA®, GESA® and ZIVA®, ARI-Armaturen is able to provide a comprehensive butterfly valve portfolio.

In contrast to centric butterfly valves, the double-offset sealing principle of the new ZEDOX® reduces the angle of the disc when entering into contact with the seat sealing ring, relieving the metallic sealing when opening. With a streamlined bearing and shape of the valve disc, ZEDOX® is able to offer higher energy efficiency and a longer service life as a result of reduced contact pressure and minimised friction, therefore allowing protection of the seat sealing ring against negative medium flow influences.

Offering high functional safety even at challenging requirements, ZEDOX® is reliably tight at temperatures from -40°C up to +260°C (max. +400°C with specially designed models), for pressure classes PN 10-PN 40 plus ANSI Class 150.

Available in butt-weld ends (DN 200-DN 1600), double flanged (DN 200-DN 1200) or wafer (DN 80-DN 800), with PN 10 – PN 40 as well as Class 150. The ZEDOX® can be made in either cast carbon steel or cast stainless steel. However, different versions and materials are available on request, making the ZEDOX® extremely versatile and suitable for use in various applications involving fluids, steam, gases and vapours.

This addition of the new ZEDOX® fills the gap in ARI-Armaturen’s range of existing soft sealing butterfly valves and the triple-offset process valve, completing our portfolio and enabling customers to benefit from our one stop shop approach.
