Could the experts please tell me what the auxiliary line on the LLS shut-off valve is used for?
Bypass: In the event of a failure in the electric/pneumatic valve, regulation and control can be carried out via the bypass!
Look, this fitting is for a heating pipeline; it’s used in heating valves and heating pipelines before they are put into operation
It should be a steam heating line, used to preheat the pipeline and prevent water hammer during the first operation.
Activated temporarily in case of a cut-off valve failure.
This valve is DN25; it shouldn’t be a bypass line. It’s similar to a heating pipeline in medium- and high-pressure steam systems. Could the original poster please provide information on the operating pressure and the medium used in this pipeline, so that everyone can make an inference?
