German Crane valve Crane model Crane price

Crane 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 turbine units and prevent steam backflow in extraction pipelines, which can cause turbine overspeed accidents. To this end, Article 8110 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 check valves of extraction units must be tight, with reliable interlock actions, and fast-closing extraction stop valves must be installed to prevent overspeed caused by extraction backflow." Currently, extraction units take measures to prevent extraction backflow.
