The Spectacle Blind Valve, also known as a figure-8 blind, is a robust mechanical device used for permanent or temporary isolation of sections in pipelines. It consists of a connected pair of metal discs—one solid (blind) and one with an open hole (spacer)—that can be rotated to either stop or allow flow.

At Optimak, we provide high-quality spectacle blinds designed for safety, durability, and ease of maintenance, ideal for industries where routine inspection, maintenance, or shutdown is required.
