1 Scope This European Standard applies to copper alloy gate valves for general use having flanged, threaded, capillary,compression orloose nut/unionbodyends. 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, 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 body may be required. Therangeof nominal sizes is DN8toDN500 andof nominal diameters is 8mm to110mm. The range of pressure designations covered is PN 6; PN 10; PN 16; PN 20; PN 25; PN 32;PN 40;PN 63 Class150andClass300. For the applicability of each nominal size/diameter and each pressure designation to the different types of valveend,see 4.1.

The terms maximum allowable pressure, PS, and test pressure, PT, defined in EU Directive 97/23/EC (PED)
NOTE are equivalent to the terms allowable pressure, ps, and test pressure, Pt, defined in EN 736-3:2008.
3.1 loose nut end body end provided with a tailpiece which retains a loose internally threaded nut or ring for connection to the mating component 3.2 union end body end provided with an external thread to which is attached a threaded nut or ring,which retains a tailpiece forconnectiontothematingcomponent 3.3 NPS alphanumeric designation of size for components of a pipework system, which is usedfor reference purposes and which comprises,for the purpose of Class designated flanges according to this standard, the letters NPs followed by a dimensionless number which is indirectly related to the physical size of the bore or outside diameter of the end connections NOTE The number following the letters NPs does not represent a measurable value and should not be used for calculation purposes exceptwhere specified in the relevant standard.See EN ISO 6708.

4 Requirements 4.1 Classification 4.1.1 Nominai sizes The nominal sizes applicable to eachtype of body end 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 normaly 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 size Vthreaded ends. NOTE 3 NPS%andNPS%are not listed inEN1759-3:2003

4.1.3 PNandClassdesignations The PN and Class designations applicable to valves having flanged, threaded and loose nut/union end body ends shallbeas specified inTable4. NOTE 1 PN 20 and PN 32 are established PN designations for threaded end copper alloy valves and are additional to the list of PN designations given in EN 1333:2006. Valves with capillary or compression ends are not designated by PN or Class. NOTE2 EN 1254-1:1998, EN 1254-2:1998, EN 1254-3:1998 and EN 1254-5:2007 which give details of the body ends for capillary and compression end valves in this European Standard, do not use the PN designation system given in EN 1333.if PN designations are allocated to capillary or compression end valves, it is the responsibility of the manufacturer to provide information on any pressure and/or temperature limitations in service.
