ARI Armaturen Check Valves
ARI Armaturen Check Valves – Backflow Prevention for Steam, Water, and Industrial Process Systems
ARI Armaturen check valves are designed to provide automatic, maintenance-free protection against reverse flow in steam, gas, and liquid pipelines. Manufactured in Germany to the highest engineering standards, ARI check valves ensure system integrity, protect equipment from pressure surges, and help maintain process efficiency in demanding industrial environments. With a comprehensive range of models and materials, ARI check valves are trusted across power generation, HVAC, chemical processing, and steam systems.
The ARI check valve range includes swing-type, lift-type, and dual-plate configurations, offering solutions for horizontal and vertical installations. Designed for low cracking pressure and reliable reseating, ARI Armaturen check valves are available with PN16 to PN40 pressure ratings and accommodate temperatures up to 450°C, depending on the valve body and internal trim materials.
Key Features of the ARI Armaturen Check Valve Range
ARI Armaturen check valves combine performance, simplicity, and durability. They are suitable for both clean and slightly contaminated media and are engineered for consistent operation over a long service life.
Core technical benefits include:
Self-acting non-return mechanism that closes automatically in the event of backflow, eliminating the need for external power or actuation.
Swing check valves with full-bore flow paths, offering minimal pressure drop and ideal for steam and condensate lines.
Lift check valves, designed for higher pressure ratings and more precise sealing, particularly in vertical pipework.
Dual-plate (wafer) check valves, offering a compact, lightweight design with spring-assisted closing for fast shut-off in high-speed systems.
Options for soft or metal seats, with tight shut-off up to Class VI depending on trim selection and application.
Standardised face-to-face dimensions and EN 558 conformity for straightforward installation and interchangeability.
Many models within the ARI Armaturen check valve portfolio, such as the ARI REYCO or the heavy-duty FABA range, are offered in a wide choice of materials including grey cast iron, ductile iron, cast steel, stainless steel, and bronze for marine or corrosive media environments.
Industry Applications of ARI Armaturen Check Valves
ARI Armaturen check valves are essential for any application where the prevention of reverse flow is critical to safety and performance.
Common industry sectors include:
Steam and condensate systems, to prevent water hammer and reverse cycling
Boiler and feedwater systems, protecting pumps and equipment from backpressure
District heating, ensuring flow direction is maintained in looped systems
Chemical and petrochemical plants, safeguarding process equipment from cross-contamination
HVAC and building services, for chilled water, hot water, and air handling systems
Marine and offshore, where reliability under vibration and thermal cycling is essential
The quick closing response and low pressure loss of ARI check valves make them particularly effective in dynamic systems where flow changes rapidly and equipment must be protected without delay.
