Safety Valves

ARI-Armaturen offers a wide range of safety valves designed to protect systems by automatically releasing pressure in the event of overpressure situations. These valves are crucial for ensuring the safety and reliability of various industrial applications, including steam, hot water, gases, and other fluids.

Key Features


Wide Range of Applications: ARI safety valves are versatile and can be used in industries such as chemical processing, power plants, and HVAC systems.

High-Quality Materials: Made from durable materials such as stainless steel, cast iron, and carbon steel, these valves ensure long-lasting performance and resistance to corrosion.

Various Connection Types: Available with flanged, threaded, or welded connections, providing flexibility for different installation requirements.

Compliance with Standards: ARI safety valves comply with major international standards, including DIN EN ISO 4126-1, PED, TRD421, and AD2000A2, ensuring they meet stringent safety and quality criteria (ARI Armaturen) (ARI Armaturen).

Product Range

SAFE Series: This series includes various models like SAFE 901, 902, 911, and 912, which are designed to handle different pressures and temperatures. These valves feature a direct-loaded spring mechanism and wear-resistant seat/disc configurations (ARI Armaturen).

REYCO Series: Known for their reliability, the REYCO safety valves are fully interchangeable with Lonergan valve series and are certified per API 526 and ASME Code Section VIII Div. 1 (Ari Armaturen).
