This European Standard shall be given the status of a national standard, either by publication of an identical

23、text or by endorsement, at the latest by April 2018, and conflicting national standards shall be withdrawn at the latest by April 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identify

24、ing any or all such patent rights. This document supersedes EN 593:2009+A1:2011. 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 2014/68/EU. For relationship with EU D

25、irective, see informative Annex ZA, which is an integral part of this document. The main technical changes compared to the previous edition are: a) the extension of the dimensions to cover PN 2,5 to PN 160, Class 150 to Class 900 and DN 20 to DN 4 000; b) the inclusion of single, double and triple e

26、ccentric designs; c) a reference to EN 16668 for valves subject to European legislation on pressure equipment; d) the addition of informative Annex D giving the correspondence between DN and NPS; e) the addition of informative Annex E on valve torque curves at different flow velocities; f) the updat

27、ing of Annex ZA according to the new PED. 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, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Y

29、pe This European Standard specifies minimum general requirements for butterfly valves having metallic bodies for use with all type of pipe end connections (e.g. wafer, lug, flange, butt welding) and used for isolating, regulating or control applications. The PN and Class ranges are: PN 2,5; PN 6; PN

30、 10; PN 16; PN 25; PN 40; PN 63; PN 100; PN 160; Class 150; Class 300; Class 600; Class 900. The size range is: 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 1 050;

DN 750 and DN 1 050 are used only for Class 150 and Class 300. Intermediate DNs are allowed upon agreement between manufacturer a

32、nd customer. For valves subject to European legislation on pressure equipment, EN 16668 applies together with this European Standard. For industrial process control valves, EN 1349 and EN 60534-2-1 apply together with this European Standard. For water supply application, EN 1074-1 and EN 1074-2 appl

33、y together with this European Standard. NOTE 1 Butterfly valves for water supply application do not comply with Annex ZA and are not CE marked because they are excluded from the pressure equipment European legislation. NOTE 2 The range of DN, applicable to each PN, for wafer and wafer lug valve type

34、s is as given in the appropriate part of EN 1092 for Type 11 flanges for the applicable material. The range of DN, applicable to each PN, for flanged valve types is as given in the appropriate part of EN 1092 for Type 21 flanges for the applicable material. The correspondence between DN and NPS is g
