ISO 12149:1999 PDF

Scope: This International Standard specifies the requirements for bolted bonnet steel globe valves for general-purpose applications and having the following features: — bolted bonnets; — flanged, threaded, socket-welding (DN 65 and smaller) or butt-welding ends; — outside screw and yoke, inside screw and rising stem; — with metallic or soft obturator (disc, piston) or seat seals. It covers valves of the following nominal sizes, DN: — 10; 15; 20; 25; 32; 40; 50; 65; 80; 100; 125; 150; 200; 250; 300; 350; 400; and applies to valves of the following nominal pressures, PN: — 10; 16; 20; 25; 40; 50; 110.
