Rotatable line blind
Rotatable Line Blind
To easily and securely shut off a pipeline or a container, with only one operator, within a few seconds without expansion of the pipeline. The position of the line blind, OPEN or CLOSED, is easy recognisable.
DN 15 up to DN 3000 (larger nominal diameters upon request)
1/2" up to 120"
PN10 up to PN100 depending on nominal diameter and type
150 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-free and tension-free pressing and release 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 pressing force.
♦ Secure shut off of the pipeline or part of the plant to ensure safe accessibility or inspection of the downstream pipelines.
