What is ISO 28921-1 - Isolating valves for low-temperature applications about?
ISO 28921-1 is a series of international standards on industrial valves that discusses the best procedures and specifications required for manufacturing high-quality industrial valves. ISO 28921-1 specifies requirements for design, dimensions, material, fabrication, and production testing of isolation valves for low-temperature applications. ISO 28921-1 applies to gate, globe, check butterfly, and ball valves and can be used for other valve types used in low-temperature services. ISO 28921-1 covers isolation valves for use in cryogenic temperature service where the design low-temperature service is –50 °C down to –196 °C. ISO 28921-1 covers valves with body, bonnet, bonnet extension, or cover made of metallic materials. ISO 28921-1 covers valves of nominal sizes DN: 10; 15; 20; 25; 32; 40; 50; 65; 80; 100; 125; 150; 200; 250; 300; 350; 400; 450; 500; 600; 650; 700; 750; 800; 850; 900, corresponding to nominal pipe sizes NPS: 3/8; 1/2; 3/4; 1; 11/4; 11/2; 2; 21/2; 3; 4; 5; 6; 8; 10; 12; 14; 16; 18; 20; 24; 26; 28; 30; 32; 34; 36, and applies to pressure designations:
PN 16; 25; 40; 100; 160; 250 Class 150; 300; 600; 800; 900; 1 500
