STOPL-S2-F1 (For PE d225-d400 pipes with an internal overpressure of up to 16 bar.)

The STOPL-S2-F1 is used to temporarily interrupt the flow of the media in pipelines with internal overpressure (or without overpressure) without any leakage of the medium (also referred to as pipeline shut-off). It involves inserting a line-stopping head fitted with a seal through a hole drilled into the pipeline, interrupting the flow of the medium. The device is connected perpendicular to the pipe axis using a custom fitting. The line-stopping head on the line-stopping rod is inserted through hydraulic telescopic cylinders.

The STOPL-S2-F1 basically has the same characteristic features as the STOPL-S-F1 series, with the following advantages:

Advantages:

• Quick and easy assembly.
• System of interchangeable lids.
• Bayonet-type locking of the loading chamber.
• Substantially reduces the preparation time for individual technological operations.
• High variability.
• Routable bypass.
• Simple bypass solution.
• High level of safety.
