Often referred to as spectacle blinds, figure of eights, or blinding systems, SchuF Line Blind valves provide a fast, easy-to-use, and safe solution to pipeline isolation. Modern line blind systems such as the SchuF Cam-Set or Cam-Slide change the installation of the blind into a one-person operation taking only minutes to complete where downstream safety is assured. In all sizes, the Cam-Set/Slide makes line blinding convenient, fast and safe.


Positive pipeline close/off is vital in many piping systems to assure the 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.
