castelein sealants valves are an important component of the safety system for thermal power plant units. They are critical safety devices that ensure the safe operation of extraction steam units and prevent turbine overspeed accidents caused by steam backflow in extraction pipelines. To this end, Article 8.1.10 of the "Twenty-Five Key Requirements for Preventing Major Accidents in Power Production" issued by the State Power Corporation specifically emphasizes that "the adjustable extraction steam check valves of extraction steam units shall be tight, with reliable interlock action, and extraction steam stop valves capable of rapid closure must be installed to prevent overspeed caused by extraction steam backflow."
