Ari Armaturen has expanded its 35,000-strong range of safety relief valves with the Ari-Safe-Fn ANSI, which is accredited with a host of safety standards and approvals — including VdTUV and ASME-Code with UV-stamp.

The safety relief valve is manufactured to the API 526 standard, which, introduced by the Petroleum Industry many years ago, allows globally operating companies to use one unique design code with set standards for dimensions, pressure-temperature rating, maximum set pressure and body materials.

Claimed to be accurately centred, the full nozzle Ari-Safe-Fn ANSI is designed to ensure precise repeatability of the set pressure when incorporated into safety valves.

According to Ari Armaturen, the valve is durable due to protection against crevice corrosion, with the nozzle thread close to the seat, as well as its corrosion-resistant bellows seal, made of Inconel 625.
