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.
