What is line blind valve (www.sammiw.com):
Line blinding has been used to pipelines in various industries wherever either positive shutoff is most concerned or full flow should be achieved without pressure drop.
The usual practice for line blinding by using typical materials such as spectacle blinds, spool piece, blind flange valves etc. with gaskets inserted between flanges has however been labour intensive & time consuming and thus resulted in making expense factors which include the time required for blinding/blanking the process, loss of productivity caused by long blinding time and also the operators of the production line have been unavoidably exposed to the potential hazard of explosion, fire, pollution and inhalation.
