BS EN 13709:2010EN 13709:2010 (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, but

20、t 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

21、 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 designat

22、ed 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: 1) PN 10; PN 16; PN 25; PN 40; PN 63; PN 100; 2) Class 150; Class 300; Class 600. b) for so

23、cket welding end valves and threaded end valves: 3) PN 40; PN 63; PN 100; 4) Class 600; Class 800. NOTE Class 800 is a Class designation widely used for socket welding and threaded end valves. 2 Normative references The following referenced documents are indispensable for the application of this doc
