ASME B16.10-2009 pdf free.Face-to-Face and End-to-End Dimensions of Valves.
1.1 General
1.1.1 Application. This Standard covers face-to-face and end-to-end dimensions of straightway valves, and center-to-face and center-to-end dimensions of angle valves. Its purpose is to ensure installation interchange- ability for valves of a given material, type, size, rating class, and end connection. Face-to-face and center-to- face dimensions apply to flanged end valves with facings defined in para. 2.3.1 and to other valves intended for assembly between flat face or raised face flanges. End-to-end dimensions apply to grooved end, buttwelding end, and flanged end valves with facings defined in para.2.3.3. Center-to-end dimensions apply to buttwelding end and to flanged end valves with facings defined in para. 2.3.3.
1.1.2 Data Source Reference. Throughout this Standard, data references are cited, e.g., “extracted from” and “compatible with.” These data are relevant to the reference standard in place at the date shown in the Foreword for American National Standards Institute approval of this Standard.
The values stated in either millimeter units (Tables 1 through 10) or inch units’ (Tables 1-1 through I-10) are to be regarded separately as standard. Within the text,the inch units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.3 Cast lron Valves
Only flanged end valves (and others intended for assembly between flanges) are covered by this Standard.Mating dimensions and facings of flanged ends conform to those in ASME B16.1. Dimensional tables for various types and sizes of valves are specified in paras. 1.3.1 through 1.3.4.
1.4 Ductile Iron Valves
Only flanged end valves (and others intended for assembly between flanges) are covered. Mating dimensions and facings of flanged ends conform to those in ASME B16.42. Valves are rated Class 150 and Class 300. The following cast Iron and steel dimensional tables are also used for ductile valves:
(a) Class 150 — Tables I and I-I
(b) Class 300 — Tables 2 and 1-2
1.5 steel and Alloy Valves
This category includes carbon, alloy, and stainless steels, and the nonferrous materials listed in ASME B16.34. It includes flanged, buttweldlng, and grooved ends, as well as the types of valves intended for assembly between flanges. Mating dimensions and facings of flanged ends conform to those in ASME B16.5, ASME B16.47, Series A, or MSS SP-44. [For flanged end butterfly valves, refer to Note (2) of Table 8 (Table 1-8) for flange information.] For flangeless or wafer valves intended for assembly between flanges, refer to Tables 7 and 8 (Tables 1-7 and 1-8) for flange information. Only buttwelding end valves in rating Classes 150 through 2500 are included in this Standard. Dimensional tables for various types and sizes of valves are specified in paras. 1.5.1 through 1.5.5.ASME B16.10 pdf free download.
