EN 13709:2002 (E) 4 1 Scope This European Standard specifies the requirements for steel globe and globe stop and check valves which are wrought, cast or fabricated in straight, angle or oblique pattern with end connections flanged, butt welding, socket welding or threaded. This standard is applicable to steel globe and globe stop and check valves mainly used for industrial and general purpose applications. However, they can be used for other applications provided the requirements of the relevant performance standards are met. The range of nominal sizes covered is: DN 8; DN 10; DN 12; DN 15; DN 20; DN 25; DN 32; DN 40; DN 50; DN 65; DN 80; DN 100; DN 125; DN 150; DN 200; DN 250; DN 300; DN 350; DN 400. DN 8 and DN 12 are not used for PN designated flanged end connections. DN 8, DN 10 and DN 12 are not used for Class designated flanged end connections. Socket welding end valves and threaded end valves are limited to the range DN 8 to DN 65. The range of pressure designations covered is: a) for flanged and butt welding end valves: PN 10; PN 16; PN 25; PN 40; PN 63; PN 100; Class 150; Class 300; Class 600. b) for socket welding end valves and threaded end valves: PN 40; PN 63; PN 100; Class 600; Class 800. NOTEClass 800 is a Class designation widely used for socket welding and threaded end valves. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
