BS EN 12288:2010EN 12288:2010 (E) 4 1 Scope This European Standard applies to copper alloy gate valves for general use having flanged, threaded, capillary, compression or loose nut/union body ends. This European Standard specifies the design and performance requirements including materials, press
23、ure/temperature ratings, dimensions, test procedures and marking. For some specific fields of application, for example, drinking water or gas, valves to this European Standard can be used provided the requirements of the relevant performance standards are met. Approval by the relevant regulatory bod
24、y may be required. The range of nominal sizes is DN 8 to DN 500 and of nominal diameters is 8 mm to 110 mm. The range of pressure designations covered is PN 6; PN 10; PN 16; PN 20; PN 25; PN 32; PN 40; PN 63; Class 150 and Class 300. For the applicability of each nominal size/diameter and each press

NOTE 1 DN is applicable to flanged valves (PN designated) and loose nut/union end valves and NPS is applicable to flanged valves (Class desig
39、nated). Threaded valves are normally identified by the thread size (NPS). Capillary and compression end valves are normally identified by nominal diameter expressed as the nominal outside diameter of the connecting tube or pipe. The use of DN for valves with body ends other than flanged is permitted
40、. NOTE 2 DN 8 is not listed in EN ISO 6708:1995 but is the commonly used equivalent nominal size for valves having size threaded ends. NOTE 3 NPS and NPS are not listed in EN 1759-3:2003.
