Blind Flange Datasheets

Types of Blind flanges

Blind flanges, abbreviated as BV, are commonly used in any industries that utilize piping. They are available in all face types (RTJ, Raised and Flat Face) at all pressure ratings. A blind can be inserted between two flanges to block flow but this isn’t good practice in most piping. When trying to block flow temporarily in a pipe, the designer should use a spectacle blind instead.  Click here to learn more about blind flanges.
