Butterfly valve double offset - ZEDOX 123 | ARI

The ARI-ZEDOX® 123 is a high-performance double-offset butterfly valve designed for demanding industrial applications involving steam, gases, or liquids. Available in sizes DN80 to DN800 and pressure ratings up to PN 40, it is constructed from durable cast steel or stainless steel. The valve features a double-offset design for reduced wear and extended service life, bi-directional tightness up to 25 bar, and a firesafe design compliant with ISO 10497/BS 6755. It is ATEX-compliant for explosive atmospheres and offers various sealing options, including PTFE+C or all-metal seats. The valve is compatible with manual, electric, pneumatic, or hydraulic actuators and is suitable for applications in steam and energy systems, marine industries, chemical processes, food and pharmaceutical plants, and HVAC systems. Technical highlights include a maximum differential pressure of up to 40 bar, operating temperatures from -40°C to +260°C, and comprehensive pressure-temperature ratings.
