Safety valves API526 - SAFE REYCO R Series | ARI

The ARI-REYCO® R Series Safety Relief Valves, compliant with API526 standards, are designed for reliable pressure relief in various systems. Key features include a direct-loaded spring for dependable operation, a wear-resistant seat/disc for enhanced durability, and precision disc alignment for smooth performance. The valves offer soft seal disc and stainless steel bellow options, catering to diverse applications. They are available in multiple nominal pressures and material options, such as SA216WCC, SA217WC6, and SA351CF8M. Technical specifications highlight material options including carbon and stainless steel, with spring materials like chrome vanadium and Inconel. The valves operate within a temperature range of -20°F to 1000°F, depending on the material and application, and are available in sizes from 1" x 2" to 8" x 10". They feature standard ANSI flange connections (ASME B16.5). The series includes models like Fig. 971 (closed lifting device), Fig. 973 (gastight cap), and Fig. 974 (open lifting device). These valves are suitable for pressure relief in systems involving neutral gases, vapors, and liquids, and are designed for applications such as steam, air, and water where overpressure protection is essential. Valve sizing is based on factors like mass or volume flow, temperature, set gauge pressure, and back pressure. The MyValve® Sizing Program is available for precise valve selection tailored to specific applications.
