Mechanical EngineersLicensed by Information Handling ServicesFOREWORDIn 1921 the American Engineering Standards Committee,later the American StandardsAssociation(ASA),organized Sectional Committee B16 to unify and further develop nationalstandards for pipe flanges 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 MechanicalContractors Association of America(MCAA),and the Manufacturers Standardization Societyof the Valve and Fittings Industry(MSS).Cosponsors were later designated as cosecretariatorganizations.Pioneer work on standardization of end-to-end dimensions of valves began in 1917 underthe direction of J.A.Stevens.It was put aside at the end of World War I and interestdid not revive until 1926.ASA and ASME agreed to include the topic in the scope of theB16 Committee,and Subcommittee 5(now Subcommittee E)was established for the purpose.Work began in 1928 and covered ferrous flanged-end gate,globe,angle,and check valves.Development of a national standard was hindered by the diversity of existing practicesand by adverse economic conditions in the early 1930s.A proposed 1933 American Standardfor face-to-face dimensions of ferrous flanged valves did not gain acceptance,even thoughit was largely based on a 1931 Standard Practice of MSS.Further work and industrydevelopments led to a meeting in May 1937,which undertook to reconcile differencesamong the draft ASA standard,two American Petroleum Institute(API)standards(5-G-1on pipeline valves and 600A on flanged OS&Y steel wedge gate valves),and a newlyupdated MSS SP-32.A revised B16 proposal was voted favorably in June 1938,was approved by ASA,andwas published in 1939.The standard was reaffirmed in 1947.Work began on a revisionin 1953 to include buttwelding end valves,plug valves,and control valves in both castiron and steel.That edition was published as ASA B16.10-1957.Further revision was begunin 1964.After reorganization of ASA,first as the United States of America StandardsInstitute(USASI),then as American National Standards Institute(ANSI),with the SectionalCommittee being redesignated as an American National Standards Committee,a new editionadding ball valves was approved and published as ANSI B16.10-1973.In 1982 American National Standards Committee B16 was reorganized as an ASMECommittee operating under procedures accredited by ANSI.In the 1986 Edition,ductileiron and the alloys covered by ANSI B16.34 were added to the materials covered.Wafertype gate and check valves,Class 150 Y-pattern globe and check valves,and several patternsof butterfly valves were added to the types covered.Inch dimensions were converted fromcommon to two-place decimal fractions.In 1991 Subcommittee E-Face-to-Face and End-to-End Dimensions of Valves,wascombined with Subcommittee N-Steel Valves.In the 1992 Edition,steel offset seat andgrooved end butterfly valves were added.Globe and flangeless style control valves,whichpreviously had been included,were removed from the Standard.Information regardingcontrol valve dimensions may be obtained from Instrument Society of America,67 AlexandriaDrive,Research Triangle Park,NC 27709.In this 2000 Edition,metric dimension tables were added.All tables and references toClass 400 steel and Class 800 cast iron were removed.All tables were renumbered.uniCOPYRIGHT American Society of Mechanical EngineersLicensed by Information Handling
