Abstract
This hydraulic safety and regulating system for a steam feed of a turbine has a rapid-action (4) and a steam regulating valve (3), and a line system monitored by a safety downward-control unit (22). The monitored line system is designed as both a power oil supply and as a safety oil system. This results in a hydraulic safety regulating system which is simple to build and has a reduced number of possible leakage points.
