About this document
Extraction Swing Check Valve Function by adehriya is a document available to read on EtoBox.
The document describes extraction swing check valves in a steam turbine. The check valves prevent backflow of steam into the turbine from extraction lines, preheaters, and moisture separators. Each extraction line contains two free-swinging check valves, with some lines containing an additional check valve assisted by a control actuator. The check valves close automatically if flow reverses to prevent backflow. The control system uses solenoid valves and changeover valves to trigger the check valves by eith
