3.3 Ring Joint Facings

The X dimension given in Table 10 (A 10), whcn added to the face-to-face dimension of a valve having raised face flanges in Tables 1 to 6 (Al to A6). establishes the end-to-end dimension for the valve having flanges with ring joint facings.

4 VARIATIONS OF LENGTh WITHIN A CLASS OF VALVES

4.1 Buttwelding End Valves (Also see Para. 2.4)

Tables I to 6 (Al to A6) include end-to-end dimensions for valves having butiwelding ends. In many cases, the dimensions are

different from those of face- to-face dimensions of flanged valves, as evidenced by the differences between dimensions A and B of

the tables.

4.1.1 Short Pattern. For pressure seal or flangeless bonnet valves having buttwelding ends in Class 600 and higher, the regular end-to-end dimensions shall be equal to the short panerri dimensions shown in Tables 3 to 6 (A3 to A6). At the manufacturer’s option, the end-to-end dimensions of these valves may be the same as the face-to-face dimensions of raised face flanged valves.

4.1.2 Long Pattern. For flanged bonnet valves having buitwelding ends in Class 600 and higher.
