ZETRIX^® – the ARI process valve for the most demanding applications.

The disc of the ZETRIX^® valve can completely shut off the flow of liquid and gaseous media by means of a 90° open/closed swivel movement. This butterfly valve is versatile, has a long service life and is reliably sealed even under the toughest operating conditions.

Your Advantages

• Available soon in a cryogenic version for temperature ranges from –196 °C

• Long service life thanks to maintenance-free and stellited sealing seat as a standard version

• Friction-free and wear-free pivoting of the valve disc due to optimised contact and closing angles

• "Intelligent" lamellar sealing ring (self-centering due to floating bearing) ensures a uniform radial closing force with minimal effort

• Hardened bearing bushes for the one-piece safety shaft

 The triple eccentric design of the disc (maximum closing force with minimum effort) is supported by an ‘intelligent’ sealing ring (uniform closing force, as it is self-centring and floats freely on the sealing surface). The multitude of additional safety options, which are always included, such as the armoured, stellited sealing seat (Stellit™ 21) as standard across all nominal sizes, supports the so-called metallic sealing principle throughout the entire life cycle and beyond. Conventional cycles consider a period of up to a maximum of 20 years, whereas ZETRIX and its finite element method-based, detailed development assumes an operating life of 30 to 50 years, among other things.

This robust durability offers unique performance in a wide range of applications across almost all areas and applications in industry, petrochemicals and building services engineering.

The ZETRIX® triple eccentric butterfly valve is also available with special drive technology, whether pneumatic or, for example, electro-hydraulic, which, among other things, also offers a so-called safety quick closure (#ESD) in less than 1 second for the switching process, the rotational movement of the butterfly valve disc.

The extensive portfolio is currently being expanded to include a cryogenic version for temperature ranges from -196 °C to -60 °C. Our ZETRIX standard range offers you a choice of temperature ranges from -60°C to +550°C in nominal pressure ratings PN 6 to PN 100 or in ASME ANSI Class 150, 300 and 600.
