LSA412-H, Hydraulic Line Stop Actuator, 4-12" (102-305 mm) Plugging Head Size

Safe, Simple and Reliable Pipeline Isolation The Enerpac Line Stop Actuators (LSA), are offered in a variety of sizes. They form part of the Enerpac Hot Tapping and Line Stopping Series that is essential to allow for cost effective isolation of pipelines to allow for maintenance and modifications avoiding interruption of service and costly shutdown. Unique anti-rotation feature The durability, ease-of-use, anti rotation feature and fail-safe locking mechanism make the Enerpac LSA a safer choice for maintenance crews repairing in-service pipelines that are under pressure. Temporarily Pipeline Isolation The LSA-Series is used to temporarily isolate a section of pipeline for repairs, maintenance or additions without the need to shut down the line. Safer, easier and more precise alignment LSA-Series Line Stop Actuators include a unique anti-rotation feature that eliminates excessive play. This ensures the folding head and sealing elements align easily within the pipe. The control bar design uses a fail-safe mechanical locking device - an important safety feature that prevents the folding head and seals from unseating if there is an unexpected spike or drop in pressure.
