40、YRIGHT International Electrotechnical CommissionLicensed by Information Handling ServicesCOPYRIGHT International Electrotechnical CommissionLicensed by Information Handling S534-7 O IEC-7-INDUSTRIALPROCESS CONTROL VALVES Part 7:Control valve data sheet 1.Introduction The writing of control valve spe
41、cifications 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 the user and the control valve
42、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,most of these standard data sheet
43、s 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 form by contractors,users and manufactu
44、rers 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 procedures by uniform display of information.2
45、.4 Provides a useful permanent record and information for checking.2.5 Improves efficiency from initial concept to the final instaliation.3.Scope This standard provides a list of requirements that are normally necessary for the procurement of the majority of control valves for process systems.No att
46、empt 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 facilities.A detailed set of instructions is include
47、d in order to ensure that the abbreviated terms are fully understood and that consistent data entries are always made.4.Standards to be considered Publication 534-1(1 987):Industrial-process control valves,Part 1:Control valve terminology and general considerations.COPYRIGHT International Electrotec
