The ARI-SAFE ANSI is a line of spring-loaded safety relief valves by ARI Armaturen, designed for industrial use with steam, gases, and liquids, meeting ANSI/ASME standards for flanged connections (like ASME B16.5) and pressure ratings (e.g., ANSI 150, 300). These valves offer features like wear-resistant seats, options for soft-sealing or bellows (EPDM/stainless steel) for better tightness, and are certified for various pressure codes, providing reliable overpressure protection for plants and processes.
Key Features & Description
- Type: Spring-loaded, direct-loaded safety relief valve.
- Standards: Complies with ANSI/ASME codes, featuring ASME B16.5 flanges and NB/UV stamps.
- Applications: Used in industrial installations, processing, and general plant manufacturing.
- Media: Suitable for steam, neutral gases, vapors, and liquids, including aggressive media with specific configurations.
- Design Options: Available with bellows (EPDM, stainless steel) for backpressure compensation and soft-seated discs for zero leakage.
- Performance: Offers wear-resistant seats/discs, precise alignment, and can be configured for specific temperature/pressure ranges.
- Certification: Type-tested and certified to standards like TUV, ASME, and ISO 9001.
How to Identify
Look for markings like "ARI-SAFE-ANSI," Figure numbers (e.g., 901, 902, 911, 912), ANSI Class (e.g., 150, 300), material (e.g., WCB), and relevant stamps (UV, NB) on the valve body.
In essence
ARI Armaturen manufactures these valves to protect equipment from excessive pressure, ensuring safe operation in various industrial environments by venting excess fluid when set pressure is reached, as per.
