1. Threaded engagement in accordance with ASME B31.3 “Chemical Plant and Petroleum Refinery Piping.”
2. Bolting lengths are base on installation of valve between standard raised face flanges utilizing flange gaskets with a final compression thickness of 0.125 inch. When gaskets used have a final
compression thickness less than 0.125 inch, reduce bolting lengths shown by 0.25 inch.
