EN 1349:2009 (E) 3 Foreword This document (EN 1349:2009) 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of an identical text or by endorsement, at the latest by May 2010, and conflicting national standards shall be withdrawn at the latest by May 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1349:2000. 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, Bulgaria, 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 the United Kingdom.

EN 1349:2009 (E) 4 Introduction This European Standard has been established on the basis of different parts of EN 60534. The terminology specific to control valves is provided in EN 60534-1. The general valve terminology can be found in EN 736-1, EN 736-2 and EN 736-3. This document differs from EN 60534-3 by addition of basic series of face-to-face dimensions and addition of other control valve types. The testing requirements of EN 60534-4 are basically the same, but hydrostatic test makes reference to EN 12266-1 which is an harmonised European Standard. The marking requirements refer to EN 19 and EN 60534-5. SIST EN 1349:2011



EN 1349:2009 (E) 5 1 Scope This European Standard applies to all industrial process control valves (hereafter referred to as control valves).

The range of nominal size is:  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 600; DN 700; DN 750; DN 800; DN 900; DN 1 000; DN 1 200. The range of PN is:  PN 10; PN 16; PN 25; PN 40; PN 63; PN 100; PN 160; PN 250; PN 320; PN 400. The range of Class is:  Class 150; Class 300; Class 600; Class 900; Class 1 500; Class 2 500; Class 4 500. Pinch valves are excluded from the scope of this European Standard. Cast iron Class designated flanges are excluded from the scope of this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE The definitions are in agreement with the definitions given in EN 60534-1:2005, but the word "control" is added in the term to differentiate these definitions and the definitions given in EN 736-1:1995. It should be noted that the word "closure member" in EN 60534-1:2005 is replaced by the word "obturator" in this European Standard and in the different parts of EN 736. An alternative term which is commonly used is "plug". 3.1 Control valve 3.1.1 control valve power operated device which changes the fluid flow rate in a process control system, consisting of a valve con
