Spectacle and line blind flanges are similar to a blind flange but different because they fit between two flanges. Spectacle blind gets their name from similarity to pair or eye glasses. Once side of Spectacle Blind Flange is fully closed for complete flow shuts off, whereas the other end is open for full flow. In this setup the blinds can be rotated without having to take the system apart. It also gives visual confirmation if the line is open or close.

A Spectacle Blinds is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device.
