23、MMISSION _ INDUSTRIAL-PROCESS CONTROL VALVES Part 7: Control valve data sheet FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
24、 international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (he
25、reafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also p
26、articipate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible
27、, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While
28、all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to
29、apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicat
30、e its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including in
31、dividual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upo
32、n, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements
33、of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60534-7 has been prepared by subcommittee 65B: Elements of systems, of IEC technical committee 65: Industrial-process measurement a
34、nd control. The text of this standard is based on the following documents: FDIS Report on voting XX/XX/FDIS XX/XX/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance wi

38、riting of control valve specifications is an extremely important segment of the complete design, purchase and fabrication of any process control system. If the wrong control valve is specified, due to either incomplete or erroneous specification, the replacement of that valve becomes costly to both
39、the user and the control valve manufacturer and often results in undue project delay. Therefore, many of the important control valve users and contractors have developed their own standard data sheets to eliminate as much misunderstanding as possible regarding the valve specifications. Unfortunately
40、, most of these standard data sheets are different from each other, confusing many valve manufacturers and subcontractors dealing with more than one valve data sheet. 2 Purpose The purpose of a standard control valve data sheet is to promote uniformity, both in content and form. General use of this
41、form by contractors, users and manufacturers offers many advantages: 2.1 Assists in preparation of a complete specification by listing and providing space for all principal descriptive options. 2.2 Promotes uniform terminology. 2.3 Facilitates quoting, purchasing, receiving, accounting and ordering
42、procedures by uniform display of information. 2.4 Provides a useful permanent record and information for checking. 2.5 Improves efficiency from initial concept to the final installation. 3 Scope This standard provides a list of requirements that are normally necessary for the procurement of the majo
43、rity of control valves for process systems. No attempt is made to include all possible requirements for any conceivable process. The list is arranged in a format designed to assist the specification writer with a standardized presentation of data and also to be a basis for use with data processing f
44、acilities. A detailed set of instructions is included in order to ensure that the abbreviated terms are fully understood and that consistent data entries are always made. 4 Standards to be considered IEC 60529:2001 (incl. am1), Degrees of protection provided by enclosures (IP Code) Licensed Copy: Lo
