ARI SAFE Safety Valve (Angle Pattern, Flanged PN40, Nodular Iron Body)

The ARI SAFE Safety Valve with angle pattern construction, PN40 flanged connections, and a nodular cast iron body is a reliable and cost-effective solution for pressure relief in steam, air, gas, and fluid systems. Designed to open automatically when system pressure exceeds a set limit, this valve protects vital equipment from damage caused by overpressure — ensuring safe and efficient operation.

Built from nodular cast iron (ductile iron), the body offers enhanced toughness and flexibility compared to grey cast iron, while maintaining excellent performance under pressure and temperature cycling. Its PN40 flange rating makes it suitable for medium to high-pressure pipelines, and the angle pattern layout provides a compact, space-efficient solution for vertical or tight installations. The ARI SAFE valve is ideal for use in heating systems, boiler protection, industrial processing, and general steam applications.

With its dependable lift performance, tight shut-off, and robust construction, the ARI SAFE Safety Valve offers long-term safety, reliability, and minimal maintenance.
