How the SchuF Fetterolf Line Blind Valves work
A Line Blind Valve is permanently installed into a pipeline. The valve´s internal cam-mechanism allows to change the plate from open to closed position within a minute.
As soon as the pipeline is drained the cam-mechanism can be opened by turning the screw (or handwheel), now the spectacle plate can be turned and positioned and finally the cam-mechanism can be closed again by closing the handwheel.

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 three variants as Cam-Set, Cam-Slide or Stacey Line Blind Valves.
