Line blind with closed housing

Line Blinds with closed housing

The closed housing is completely gas tight. The compact design with its threaded holes enables easy installation. 
For actuation the seat is released via handwheel or hydraulic pump and after realignment pressed on again. The disc is moved with a handwheel via spindle actuation . 

Other versions of activation are also possible. 

To easily and securely shut off a pipeline or a container, with only one operator, within a few seconds without expansions of the pipeline.

The position indicator shows the position of the line blind, OPEN or CLOSED. 

DN 100 to DN 3000
4" to 120"
up to PN100 depending on nominal diameter and type
up to 600 Lbs depending on nominal diameter and type

• No expansion of the pipeline, thus avoiding tensions within the pipeline. 
• The unique SAMMI mechanism enables the almost wear and tension free pressing and releasing of the sealing seat to actuate the line blind. 
• The disc is moved automatically into its end position via stops, this ensures an exact and seamless alignment to the pipeline. 
• Optional: Torque indicator for the correct setting of the press force. 

♦ Secure shut off of the pipeline or part of the plant to ensure safe accessibility or inspection of the downstream pipelines.
