ARI-Armaturen: ZEDOX® – The New High Performance Valve

ARI-Armaturen is delighted to present a double-offset, metallic sealing high performance valve – ZEDOX®. A durable, energy-efficient valve that 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 more comprehensive butterfly valve portfolio.

The double-offset sealing principle of the new ZEDOX® reduces the angle of the disc when it enters into contact with the seat sealing ring which relieves the metallic sealing when opening. Due to the shape of the valve disc, ZEDOX® is able to offer higher energy efficiency in addition to 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 conditions, 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.

ZEDOX® accomplishes leakage rate A acc. to EN12266, API 598 (bi-directional) and soft sealing or alternative metallic-sealing with leakage rate B (optional rate A); with the blowout proof shaft providing extra safety. The ZEDOX® pressure/temperature rating follows EN 1092. The high performance valve can be easily automated, using pneumatic, electrical or hydraulic actuators.

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 carbon steel or stainless steel however, different versions and materials are available on request. This makes the ZEDOX® extremely versatile and suitable for use in various applications involving fluids, steam, gases and vapours.

The addition of the new ZEDOX® compliments the range of existing soft sealing butterfly valves and triple-offset process valve, enabling our customers to benefit from our ‘One Stop Shop’ approach:

• ZETRIX® - the process valve: available in butt-weld ends, double flanged and fully lug-type versions up to Class 600, PN 63 and PN 100 and from DN 80 - DN 600.
• ZEDOX® - the high performance butterfly valve: available in butt-weld ends, double flanged and wafer-type versions up to PN 40 and DN 80 - DN 800 (DN 1600).
• ZESA®, GESA®, ZIVA® - the eco-centric butterfly valves: available in lug and wafer-type versions up to PN 16 and DN 25 - DN 500.
