Slidable line blind

To easily and securely shutt off a pipeline or a container, with only one operator, within a few seconds without expansion of the pipeline. The position indicator shows the position of the line blind. OPEN or CLOSED is easely identifiable.

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 tension within the pipeline.
The unique SAMMI mechanism enables the almost wear and tension free clamping 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 clamping force.

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