Abstract (en)
[origin: EP0451543A1] This actuating system for a steam regulating valve (2) has a control valve arrangement for controlling the operating pressure of an actuating system (1). <??>It is intended to create an actuating system for a steam regulating valve which can always be operated safely and quickly even with a comparatively high oil pressure. This is achieved in that the control valve arrangement has at least two controllable control valves (17, 21) which are pressure-operated via at least one servo control valve (proportional pressure valve 29, 34). <IMAGE>
