ASME B16.10:2000 pdf download FACE-TO-FACE AND END-TO-END DIMENSIONS OF VALVES
1 SCOPE
1.1 General
This Standard covers face-to-face and end-to-enddimensions of straightway alves, and center-to-face andcenter-to-end dimensions of angle valves. Its purpose isto assure installation interchangeability for valves of agiven material, type, size, rating class, and end connection. Face-to-face and center-to-face dimensions applyto flanged end valves with facings defined in para.2.3.1 and to other valves intended for assembly betweenflat face or raised face flanges. End-to-end dimensionsapply to grooved end, buttwelding end, and flangedend valves with facings defined in para. 2.3.3. Center-to-end dimensions apply to buttwelding end and toflanged end valves with facings defined in para. 2.3.3In Tables 1 to 6 (Tables Al to A6),A or D in acolumn head denotes valves having flanged ends asillustrated; B or E denotes valves having buttweldingends.
1.2 Standard Units
The values stated in either millimeter units (TablesI to 10) or inch units’ (Tables Al to A10) are to beregarded separately as standard. Within the text, theinch units are shown in parentheses. The values statedin each system are not exact equivalents, therefore.each system must be used independently of the other.Combining values from the two systems may result innonconformance with the standard.
1.3 Cast Iron.Valves
Only flanged end valves (and others intended forassembly between fanges) are covered by this StandardMating dimensions and facings of fanged ends conformto those in ASME B16.1. Dimensional tables for varioustypes and sizes of valves are as follows.
1.3.1 Gate, Plug, and Check Valves
(a) Class2 125 – Tables l and Al
(b) Class 250 — Tables 2 and A2
1.3.2 Globe and Angle Valves
(a) Class 125 – Tables 1 and Al
(b) Class 250 — Tables 2 and A2
1.3.3 Wafer Swing Check Valves
(a) Class 125 — Tables 7 and A7(b) Class 250 – Tables 7 and A7
1.3.4 Butterfly Valves(a) Class 25 — Tables 8 and A8(b) Class 125— Tables 8 and A8
1.4 Ductile Iron Valves
Only flanged end valves (and others intended forassembly between flanges) are covered. Mating dimensions and facings of flanged ends conform to those inASME B16.42.Valves are rated Class 150 and Class300. The following cast iron and steel dimensionaltables are also used for ductile valves.
(a) Class 150 -Tables 1 and A1(b) Class 300 – Tables 2 and A2
1.5 Steel and Alloy Valves
This category includes carbon, alloy, and stainlesssteels, and the nonferrous materials listed in ASMEB16.34. It includes flanged,buttwelding. and groovedends, as well as the types of valves intended forassembly between flanges. Mating dimensions and facings of flanged ends conform to those in ASME B16.5
