BS EN 1984:2010EN 1984:2010 (E) 4 1 Scope This European Standard specifies the requirements for steel gate valves which are wrought, cast or fabricated with end connections flanged,
19、 butt welding, socket welding or threaded. This European Standard is applicable to steel gate 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 ranges of nom
20、inal 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 450; DN 500; DN 600; DN 700; DN 750; DN 800; DN 900; DN 1000. DN 750 is used for Class designated valves only. DN 8 and DN 12 are not
21、used for 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 valves 1) PN 10; PN 16; PN 25; PN 40; PN 63; PN 100 2) Class 150; Class 300; Class 600 b) for butt welding end val
22、ves 1) PN 10, PN 16, PN 25, PN 40, PN 63, PN 100 2) Class 150, Class 300, Class 600 c) for socket welding end valves and threaded end valves 1) PN 10; PN 16; PN 25; PN 40; PN 63; PN 100 2) Class 600; Class 800 NOTE 1 Socket welding end and threaded end valves are not normally manufactured with the p
23、ressure designations PN 10, PN 16, PN 25 and PN 40. NOTE 2 Class 800 is an intermediate 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 document.
