Line Blinds

 
Line blinds are safety devices designed for positive shut-off of piping, equipment or storage tanks where positive shut-off is defined as a device in a closed, drop-tight, verifiable, and maintainable position. This positive shut-off feature makes line blinds perfectly attuned for permanent or long-term piping system isolation and shutdown.  
 
Advantages of Line Blinds
  • Quickly isolates lines compared to spectacle blinds
  • Saves money on labor and equipment when isolating systems
  • Zero-leakage compared to some isolation valves
