Hydraulic controls for water, steam, and gas turbines

Turbine Controls

Precision, safety, and reliability for turbine plants

For over four decades, Keicher Engineering AG has been developing customized, robust hydraulic systems for controlling turbines in power plant and industrial applications. Our systems take on central functions in the regulation of guide vanes, valves, quick-closing mechanisms, and other safety-critical components – both in new installations and retrofit projects.

Overview of System Components

The hydraulic control systems from Keicher consist of modular components that can be individually combined depending on the turbine type and application case. This ensures flexible adaptation to different technical requirements – from compact units for island solutions to complex multi-loop controls in large systems.

  • Hydraulic Power Units (electric or diesel drive)
  • Accumulator stations, cooling circuits
  • Control blocks with valves and throttle stages
  • Sensors for pressure, position, and temperature monitoring
  • Electric or PLC-controlled regulation
  • Control cabinet including visualization (optional with touch panel)
