2 Lengths are based on the minimum FLANGE thickness of weld neck flanges per ANSI and use of standard 1/16 gaskets. Stud lengths also assume heavy hex nut heights per ANSI : When using metallic spiral wound gaskets, add 1/8 to bolt and stud length dimension JOURNAL HOLES: The 20 and 24 Wafer and Lug pattern valves have tapped blind holes near the stem journal (upper and lower). These sizes list a second length for these holes only. Standard lengths must be used on all other FLANGE Sizes 16 to 24 : The lugs of the 16 to 24 lug pattern valves are not tapped through the entire body. Bolt and stud lengths are based on usable thread depth.
