The SchuF Group designs and manufactures a fast, easy to use and safety conscious Line Blind Valve range. They are often refered to as spectacle blinds, figure of eights, or blinding systems.

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.
