8、his document (EN 15081:2007) 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 Apri
9、l 2008, and conflicting national standards shall be withdrawn at the latest by April 2008. 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 rig

EN 15081:2007 (E) 4 1 Scope This European Standard provides requirements for metallic mounting kits for part-turn on-off valves and actuat
12、or attachments to enable safe and reliable operation. It includes all components transmitting torques from actuators to valves with a maximum flange torque up to 16 000 Nm (up to F30 flange type). It applies to part-turn valves and actuators having attachment flanges and drive components as describe
13、d in EN ISO 5211. It includes recommendations and methods for design and environmental corrosion protection. When reference is made to this European Standard, all the requirements apply, unless otherwise agreed between the purchaser and the manufacturer/supplier, prior to order. For the scope of thi
14、s European Standard, the term “Valve” covers valve or shaft extension top-flange. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the
