State theatre Dresden

The main valve stages in the low pressure water hydraulic system, which operates the three lifting platforms in the substage and is about 100 years old, had to be replaced due to heavy abrasive wear. The newly developed main valve stage with a nominal size of 100 mm led to a considerable improvement in positioning behaviour.

  • Analysis of the existing water hydraulic system with the help of the simulation
  • Development of a new sliding gate valve/sleeve valve system with precision control of geometry for improved positioning of the lifting platform
