The ARI-ZEDOX 123 is a high-performance, double-offset butterfly valve designed for reliable shut-off in demanding industrial applications, featuring a
cast steel/stainless steel body,
bi-directional tightness, replaceable seats, and options for metallic (CS) or PTFE+C (TS) sealing, offering long life, low operating torque,
ATEX certification, and compatibility with various actuators for automation in water, steam, oil, gas, and other systems.
Key Features & Design
- Double Offset: The pivot points are offset from the centerline, creating a cam-like action for minimal contact between disc and seat, reducing wear and friction.
- Sealing: Available with soft PTFE+C (TS) for tight shutoff or metallic (CS) seats for higher temperatures (up to 260°C).
- Tightness: Provides bi-directional sealing, meeting high leakage class standards (Leakage Rate A for soft, B for metallic).
- Body/Seat: Cast steel or stainless steel body, with a replaceable seat ring for extended service life.
- Automation: Designed for easy automation with standard interfaces (ISO 5211) for electric, pneumatic, or hydraulic actuators.
Applications & Performance
- Media: Suitable for cooling water, hot water, steam, gas, thermal oil, acids, alkalis, and more.
- Industries: Used in power plants, refineries, chemical, HVAC, shipbuilding, and general plant construction.
- Conditions: Handles challenging conditions with high reliability, even at high differential pressures (up to 25 bar).
Certifications & Compliance
- Firesafe: Complies with ISO 10497 / BS6755.
- ATEX: Approved for explosive atmospheres.
- Standards: Designed to EN 12516, PED, API 609.
