The
ARI-FABA Supra is a high-quality, maintenance-free bellows-sealed globe valve designed for demanding industrial and chemical uses like steam, hot water, thermal oil, and aggressive media, featuring robust construction, a double-wall bellows for reliability (10,000 cycles), guided stem, and options for various materials, connections (flanged, welded, threaded), and plug types (metal, soft, V-port) for precise shut-off or regulation, with easy actuator retrofitting.
Key Features & Design:
- Sealing: Double-wall metallic bellows (welded to bonnet) provide superior leak protection, tested for high cycle counts (10,000+), with secondary stem back-sealing.
- Versions: Available in 'I' (Industrial, shielded bellows) and 'C' (Chemical, flushed bellows) versions for specific media compatibility, notes Lavastica and Ebora.nl.
- Stem/Plug: Guided stem with roll-hardened thread for stability; features a metal-seated plug with a marginal seat, with regulating, balanced, or V-port options.
- Body: Made from various materials (cast/nodular iron, stainless/carbon steel) with straight-through (standard), Y-pattern, or angle body designs.
- Connections: Flanged (EN/ANSI), welded, or threaded options available.
- Actuation: Designed for easy retrofitting with pneumatic or electric actuators.
- Safety: Incorporates a double-chambered yoke gasket and often features a protective sleeve for the bellows.
Applications:
- Power stations, flue gas purification, general plant manufacturing.
- Process technology, gas supply, thermal oil, hot/process water.
- Chemical facilities, vacuum systems, district heating
