This European Standard applies to copper alloy ball valves for general use having, flanged, threaded, capillary or compression or loose nut/union body ends. This European Standard does not apply to copper alloy ball valves for drinking water applications. This European Standard specifies the design and performance requirements including materials, pressure/temperature ratings for the shell and body seats, dimensions, test procedures and marking. For some specific fields of application, for example 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 6 to DN 300 and of nominal diameters 6 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 pressure designation to the different types of valve end, see 4.1.
