【Note】
1. Please see groove design in Technical Section if applied to flanges other than JIS B2290 Flange.
2. When used in standard flange, study tightening load in advance to avoid lack of bolt tightening load.
3. This table applies to OD open configuration. Please consult VALQUA for ID open configuration.
