Industry Using Line Blinding Systems

Their primary use is to completely close off the downstream portion of a pipeline in a safe way. They are frequently found in the Petrochemical, Steel, Pulp and Paper, Maritime and Oil & Refinery industries. They are often refered to as spectacle blinds, figures of eight, spectacle plates or paddle blinds.

Line Blind Valve Applications

Positive pipeline close/off is vital in many piping systems to assure safety of personnel working on downstream equipment, particularly when flammable, toxic liquids or gases could seep past a closure. When visible proof of shut/off is necessary, a line blind is mandatory to comply with plant safety regulations. Available in two variants as Cam-Set or Stacey Line Blind Valves.
