DESCRIPTION
1.1 This practice covers the rapid determination of the A-D dimension defined as the centerline dimension from the top plane of the valve mounting cup curl to the far end of the dip tube.2 See Fig. 1.
1.2 This practice is limited to valves with 1-in. (25.4-mm) mounting cups.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
