25、ng flanged, threaded, capillary, compression or loose nut/union body ends. This European Standard specifies the design and performance requirements including materials, pressure/temperature ratings, dimensions, test procedures and marking. For some specific fields of application, for example, drinki

26、ng 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 body 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 press

27、ure designations covered is PN 6; PN 10; PN 16; PN 20; PN 25; PN 32; PN 40; PN 63; Class 150 and Class 300.

41、d shall be as specified in Tables 1 and 2. NOTE 1 DN is applicable to flanged valves (PN designated) and loose nut/union end valves and NPS is applicable to flanged valves (Class designated). Threaded valves are normally identified by the thread size (NPS). Capillary and compression end valves are n

42、ormally 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. NOTE 2 DN 8 is not listed in EN ISO 6708:1995 but is the commonly used equivalent nominal size for valves having s

43、ize threaded ends. NOTE 3 NPS and NPS are not listed in EN 1759-3:2003.
