EN 1983:2006 (E) 3 Foreword This document (EN 1983:2006) has been prepared by Technical Committee CEN/TC 69 “Industrial valves”, the secretariat 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of an identical text or by endorsement, at the latest by November 2006, and conflicting national standards shall be withdrawn at the latest by November 2006. This document has been prepared under a mandate given to CEN by the European Commission and the European Free 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. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 1983:2006 (E) 4 1 Scope This European Standard specifies requirements for industrial steel ball valves having flanged, threaded, socket welding or butt welding ends. The DN range is:  DN 4 ; DN 6 ; DN 8 ; DN 10 ; 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 450 ; DN 500 ; DN 550 ; DN 600 ; DN 650 ; DN 700 ; DN 750 ; DN 800 ; DN 850 ; DN 900. The PN and Class ranges are:  PN 6 ; PN 10 ; PN 16 ; PN 25 ; PN 40 ; PN 63 ; PN 100 ;  Class 150 ; Class 300 ; Class 600 ; Class 900 ; Class 1 500 ; Class 2 500 ; Class 4 500. This European Standard applies to steel ball valves mainly used for industrial and general purpose applications. However, they can be used for other applications provided the requirements of the relevant performance standard are met. 2 Normative references The following referenced documents are indispensable for the application of this document.
