Heavy Industrial Valve & Steam System Leader

ARI Armaturen stands as a premier global manufacturer and innovator of heavy industrial valves, pressure management systems, and advanced steam trapping solutions. Globally recognized for engineering rugged, precision-engineered flow control technology, ARI specializes in mastering the most demanding media, including high-pressure steam, thermal oil, gases, and aggressive chemicals. Their comprehensive, systems-based portfolio is purposely built to deliver complete, single-source compatibility that drives thermal efficiency, operational safety, and fluid containment across critical infrastructure.

By focusing on German engineering discipline and application-specific designs, ARI ensures that tight shut-off, precise modulation, and reliable overpressure protection remain absolute. Choosing ARI Armaturen solutions provides heavy industrial processing facilities with access to a massive portfolio of durable, field-proven configurations, backed by deep technical application knowledge and local lifecycle support to prevent costly plant downtime.

High-Precision Control & Pressure Regulation

In the realm of flow modulation, ARI offers an extensive lineup of STEVI® control valves engineered for exceptional throttling accuracy under harsh operating conditions. The portfolio features heavy-duty linear control valves equipped with shaft-guided plugs, multi-stage noise-reducing trims, and robust pneumatic or PREMIO® electric actuators to manage high differential pressures effortlessly. Complementing these are self-operating pressure regulators, including the PREDU® pilot-operated valves, which maintain precise downstream pressure stability despite fluctuating inlet pressures or volatile flow rates.

Zero-Leakage Isolation & Process Sealing

For positive fluid containment, ARI sets the global standard with its specialized isolation valve technologies. The industry-renowned FABA® series utilizes a double-walled stainless steel bellows seal to guarantee zero-leakage maintenance-free performance in dangerous thermal oil, steam, and volatile gas lines. For large-bore and severe-service applications, the ZETRIX® triple-offset metallic-sealed butterfly valve provides a self-aligning, bidirectional tight shut-off capable of enduring extreme mechanical stresses and cryogenic temperatures without degradation.

Certified Plant Overpressure Safety

ARI provides certified plant defense loops with its comprehensive SAFE® and REYCO® safety relief valve series. Engineered to react with absolute precision when allowable system limits are breached, these valves conform strictly to VdTÜV, ASME, and API 526 standards. Featuring advanced plug-guiding geometries and optimal huff capacities, they ensure critical safety loops are protected. Facilities can also deploy the patent-pending SAFE-Check service system to test installed safety valves dynamically without increasing boiler pressure or risking media loss.

Advanced Steam Trapping & Thermal Systems

Beyond individual components, ARI excels in complete thermal energy management with its advanced CONA® steam trap range. The lineup spans high-efficiency ball float, bimetallic, and thermodynamic steam traps engineered to eliminate disruptive condensate quickly and preserve dry, safe steam delivery. To streamline plant engineering, ARI aggregates these technologies into pre-engineered, modular skid packages—such as CORsys® condensate recovery stations and PREsys® pressure reducing manifolds—bridging global fluid mechanics with your facility’s energy conservation goals.
