This document is applicable to isolation valves for use in low and cryogenic temperature service where the design low-temperature service is -50 °C down to -196 °C. This document does not apply to valves for cryogenic services, designed in accordance with ISO 21011, used with cryogenic vessels. Where the requirements of this document vary from those given in the valve product standards, the requirements of this document apply. This document is applicable to valves with body, bonnet, bonnet extension or cover made of metallic materials. This document is applicable to: - 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; 950; 1 000; 1 050; 1 200; 1 350; 1 400; 1 500; 1 600; 1 650; 1 800, - corresponding to nominal pipe sizes NPS: 3/8; 1/2; 3/4; 1; 1 1/4; 1 1/2; 2; 2 1/2; 3; 4; 5; 6; 8; 10; 12; 14; 16; 18; 20; 24; 26; 28; 30; 32; 34; 36; 38; 40; 42; 48; 54; 56; 60; 64; 66; 72, and applies to pressure designations: - PN 16; 25; 40; 100; 160; 250; 400, - Class 150; 300; 600; 800; 900; 1 500; 2 500.
