Safety valves API526 - SAFE REYCO RL Series | ARI

The Safety Valves API526 - SAFE REYCO RL Series by ARI are designed for high-performance pressure relief applications. Key features include a direct-loaded spring design with a wear-resistant seat/disc and precision disc alignment. These valves are available in various materials, such as SA216WCC, SA351CF8M, and Chrom-Vanadium for the spring, with Inconel options for high-temperature applications. They support a wide range of pressure classes, including ANSI 1500, 300, 600, 900, and 1500, and can handle temperatures up to 750°F for Inconel springs and 650°F for chromium vanadium springs. The valves come in different orifice sizes, ranging from 0.078 in² to 0.563 in², and are available in sizes from 1/2" x 1" to 2" x 2". They offer various inlet and outlet connection types, including NPT threads, socket weld, butt weld, and flanges. Suitable for gases, vapors, and liquids, these valves are ideal for industries requiring pressure relief in high-pressure environments, such as steam, air, and water systems. Capacity data is provided for air and gas, with charts detailing flow capacities for different valve sizes and set pressures, including 10% overpressure. Customization options include different connection types like NPT, flanges (ANSI B16.5), socket weld ends, and butt-weld ends. The document also outlines the necessary details for valve sizing, such as mass flow, temperature, set pressure, and back pressure for various mediums. Spring materials include Chrom-Vanadium for up to 650°F and Inconel for temperatures above 650°F.
