Key Product Lines from ARI Armaturen
The core offering of ARI Armaturen is divided into four major functional categories:
Isolation Valves – Including bellows sealed globe valves, gate valves, and butterfly valves designed for shut-off duties in steam, thermal oil, and hot water systems. The ARI FABA series is a flagship range in this category, known for zero-emission sealing and high integrity.
Control Valves – The renowned ARI STEVI range covers pneumatically and electrically actuated control valves used in modulating steam and process control systems. These valves are available with modular trims, intelligent positioners, and high Kv values for precise flow regulation.
Safety Valves – Designed in accordance with EN ISO 4126, ARI safety valves offer overpressure protection for boilers, pipelines, and pressurised vessels. Models include options for saturated steam, gases, and corrosive fluids.
Steam Traps & Ancillary Equipment – Under the CONA brand, ARI offers a full portfolio of mechanical, thermostatic, and thermodynamic steam traps. The range also includes pressure reducing valves, non-return valves, strainers, and air vents — essential for complete steam and condensate systems.
Across all categories, ARI Armaturen maintains a strong focus on modularity, allowing for customised assemblies based on process conditions and end-user requirements.
