Abstract
ISO 28921-1:2013 specifies requirements for design, dimensions, material, fabrication and production testing of isolation valves for low-temperature applications. It applies to gate, globe, check, butterfly and ball valves and can be used for other valve types used in low-temperature services.
ISO 28921-1:2013 covers isolation valves for use in cryogenic temperature service where the design low-temperature service is ?50 °C down to ? 96 °C. It covers valves with body, bonnet, bonnet extension or cover made of metallic materials.
ISO 28921-1:2013 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; ½; ; 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.
It applies to pressure designations:
- PN 16; 25; 40; 100; 160; 250;
- Class 150; 300; 600; 800; 900; 1 500.
