EN 13709:2002 (E)3ForewordThis document EN 13709:2002 has been prepared by Technical Committee CEN/TC 69 "Industrial valves", thesecretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by April 2003, and conflicting national standards shall be withdrawn at the latest byApril 2003.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.In this European Standard the annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.SIST EN 13709:2003



EN 13709:2002 (E)41 ScopeThis European Standard specifies the requirements for steel globe and globe stop and check valves which arewrought, cast or fabricated in straight, angle or oblique pattern with end connections flanged, butt welding, socketwelding or threaded.This standard is applicable to steel globe and globe stop and check valves mainly used for industrial and generalpurpose applications. However, they can be used for other applications provided the requirements of the relevantperformance standards are met.The range of nominal 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 8 and DN 12 are not used for PN designated flanged end connections.DN 8, DN 10 and DN 12 are not used for Class designated 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 and butt welding end valves:PN 10; PN 16; PN 25; PN 40; PN 63; PN 100;Class 150; Class 300; Class 600.b) for socket welding end valves and threaded end valves:PN 40; PN 63; PN 100;Class 600; Class 800.NOTEClass 800 is a Class designation widely used for socket welding and threaded end valves.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter.

EN 13709:2002 (E)63 Terms and definitionsFor the purposes of this European Standard, the definitions of types of valves and components and the definitionsof terms given in EN 736-1, EN 736-2 and EN 736-3 apply.NOTEThe terms maximum allowable pressure, PS, and test pressure, PT, defined in EU Directive 97/23/EC (PED) areequivalent to the terms allowable pressure, ps, and test pressure, pt, defined in EN 736-3.4 Requirements4.1 Design4.1.1 Materials4.1.1.1The body and bonnet materials shall be selected from those listed in EN 1503-1 and EN 1503-2.4.1.1.2All the internal parts in contact with the fluid shall be made of a material whose corrosion resistance tothe fluid being carried is at least equal to the body and bonnet material.4.1.1.3Trim materials shall have a chemical composition and mechanical properties, which ensure themechanical integrity of the valve.The trim comprises the following:a) stem;b) obturator seat;c) body seat;d) backseat (for valves DN 50 and above, when fitted).4.1.1.4Stems shall be manufactured from forged, drawn or rolled material. They shall have a minimumcorrosion resistance equivalent to a 13 % chromium content ferritic steel.4.1.2 Pressure/temperature ratings4.1.2.1The pressure/temperature ratings shall be as specified in prEN 12516-1 for the particular body/bonnetmaterial group.4.1.2.2The pressure temperature ratings applicable to Class 800 socket welding and threaded end valvesshall be the Class 600 rating for the applicable material group multiplied by the ratio of 800 : 600.4.1.2.3Restrictions of temperature and pressure below those specified in 4.1.2.1 and 4.1.2.2 for example,those imposed by soft seals, special trims and bellows seal shall be indicated on the valve (see 8.1.2).4.1.2.4For temperatures below the lowest temperature shown in the pressure/temperature rating tables inprEN 12516-1 the maximum allowable pressure shall be no greater than the pressure corresponding to the lowesttemperature in the rating tables. The use of valves at lower temperatures than shown in the rating tables ispermitted providing the bending rupture energy of the body and bonnet material measured on three10 mm x 10 mm specimens, in accordance with EN 10045-1, shall be no less than an average of 27 J at atemperature no higher than the lowest scheduled operating temperature.SIST EN 13709:2003
