15、ges and fittings (and, later, for valves, gaskets, and valve actuators).Cosponsors of the B16 Committee were The American Society of Mechanical Engineers (ASME),the Heating and Piping Contractors National Association now the Mechanical ContractorsAssociation of America (MCAA), and the Manufacturers

16、Standardization Society of the Valveand Fittings Industry (MSS). Cosponsors were later designated as cosecretariat organizations.Pioneer work on standardization of end-to-end dimensions of valves began in 1917 under thedirection of J. A. Stevens. It was put aside at the end of World War I and intere

17、st did not reviveuntil 1926. ASA and ASME agreed to include the topic in the scope of the B16 Committee, andSubcommittee 5 (now Subcommittee E) was established for the purpose. Work began in 1928and covered ferrous flanged-end gate, globe, angle, and check valves.Development of a national standard w

18、as hindered by the diversity of existing practices andby adverse economic conditions in the early 1930s. A proposed 1933 American Standard for face-to-face dimensions of ferrous flanged valves did not gain acceptance, even though it was largelybased on a 1931 Standard Practice of MSS. Further work a

19、nd industry developments led to ameeting in May 1937, which undertook to reconcile differences among the draft ASA standard,two American Petroleum Institute (API) standards (5-G-1 on pipeline valves and 600A on flangedOS however, they shouldnot contain proprietary names or information.Requests that

20、are not in this format will be rewritten in this format by the Committee priorto being answered, which may inadvertently change the intent of the original request.ASME procedures provide for reconsideration of any interpretation when or if additionalinformation that might affect an interpretation is

21、 available. Further, persons aggrieved by aninterpretation may appeal to the cognizant ASME Committee or Subcommittee. ASME does not“approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity.Attending Committee Meetings. The B16 Standards Committee regularly h

This Standard covers face-to-faceand end-to-end dimension

23、s of straightway valves, andcenter-to-face and center-to-end dimensions of anglevalves. Its purpose is to ensure installation interchange-ability for valves of a given material, type, size, ratingclass, and end connection. Face-to-face and center-to-face dimensions apply to flanged end valves with f

24、acingsdefined in para. 2.3.1 and to other valves intended forassembly between flat face or raised face flanges. End-to-end dimensions apply to grooved end, buttweldingend, and flanged end valves with facings defined inpara. 2.3.3. Center-to-end dimensions apply to buttweld-ing end and to flanged end

25、 valves with facings definedin para. 2.3.3.1.1.2 Data Source Reference. Throughout thisStandard, data references are cited, e.g., “extractedfrom” and “compatible with.” These data are relevantto the reference standard in place at the date shown inthe Foreword for American National Standards Institut

26、eapproval of this Standard.1.2 Standard UnitsThe values stated in either millimeter units (Tables 1through 10) or inch units1(Tables I-1 through I-10) areto be regarded separately as standard. Within the text,the inch units are shown in parentheses. The valuesstated in each system are not exact equi

27、valents; there-fore, each system must be used independently of theother. Combining values from the two systems mayresult in nonconformance with the standard.1Linear inch dimensions in this Standard are expressed usingtwo-place decimal fractions. These values are actually commonfractions of an inch r

Valves are rated Class 150 and Class 300.The following cast iron and steel dimensional tables arealso used for ductile valves:(a) Class 150 Tables 1 and I

32、-1(b) Class 300 Tables 2 and I-21.5 Steel and Alloy ValvesThis category includes carbon, alloy, and stainlesssteels, and the nonferrous materials listed inASME B16.34. It includes flanged, buttwelding, andgrooved ends, as well as the types of valves intendedfor assembly between flanges. Mating dimen

37、 digitswhere limits, maximum or minimum values, are speci-fied, shall be “rounding off” as defined in ASTM PracticeE29. This requires that an observed or calculated valueshall be rounded off to the nearest unit in the lastright-hand digit used for expressing the limit. Decimalvalues and tolerance do

38、 not imply a particular methodof measurement.2 DEFINITIONS2.1 Valve Size Designation2.1.1 Nominal Diameter (DN). The size of a valve isdesignated by the nominal size of its end connections.This is denoted by (DN), a dimensionless number indi-rectly related to the physical size of the connecting pipe

39、See Tables 1 through 10 (Tables I-1 through I-10). Thevalve size is not necessarily the same as the inside diame-ter or port diameter.2.1.2 Valve Size Designation. NPS, followed by adimensionless number, is the designation for nominalvalve size. NPS is related to the reference nominal diame-ters, DN

40、, used in international standards. The relation-ship is, typically, as follows:2NPS DN148381012153420125114321124025021265384 100GENERAL NOTE: For NPS 4, the related DN p 25 multiplied by theNPS number.2.1.3 Reduced Port Valves(a) Reduced port, gate, and ball valves conforming toAPI 6D are designate

41、d for size by two numbers, the firstbeing the NPS on the valve ends, the second being theNPS of the port (seats, moving parts, etc.); e.g., NPS 6H11547 4 designates a valve of end size NPS 6 with a port tomatch NPS 4. These valves shall have face-to-face orend-to-end dimensions corresponding to valv

42、es havingthe same size end connections; i.e., a NPS 6 H11547 4 valveshall have the face-to-face or end-to-end dimensions ofa NPS 6 valve.(b) Reduced port, pressure seal bonnet, gate, globe,and check valves are designated for size by three num-bers, the first and last being the NPS of the valve ends,

43、the second being the NPS of the port; e.g., NPS 6H115474H115476designates a valve having ends matching NPS 6 with aport to match NPS 4. Likewise, NPS 6 H11547 4 H11547 4 woulddesignate a valve having one end matching NPS 6, theother matching NPS 4, and the port matching NPS 4.These valves shall have

44、 face-to-face or end-to-enddimensions corresponding to valves having the sameport size; i.e., either a NPS 6 H11547 4 H11547 6oraNPS6H11547 4 H11547 4valve shall have the face-to-face or end-to-end dimen-sions of a NPS 4 valve.2.2 Pressure Rating DesignationsClass, followed by a dimensionless number

45、, is thestandardized designation for pressure temperature-ratings used for valves. The numerical designations inuse are as follows:(a) for cast iron: 25, 125, 250(b) for ductile iron: 150, 300(c) for steel:2150, 300, 600, 900, 1500, 25002.3 Flanged Valve Dimensions2.3.1 Face-to-Face. The face-to-fac

46、e dimension forflanged valves is the distance between the extreme endswhich are the gasket contact surfaces (see Fig. 1). Face-to-face applies to flanged valves having the followingnominal flange facing identifiers:(a) flat2Includes all ferrous and nonferrous materials in ASME B16.34.ASME B16.10-200
