In energy plants, extremely high forces are bundled and controlled. Since the advent of hydropower, and hydraulic control systems have been used for this. They regulate water supply, for example, and control the angles of turbine blades. In the wind energy sector, the rotor blades settin angle can be adjusted hydraulically in a similar way as with water turbines. In addition, hydraulic brake systems are used in wind power plants to decelerate the turbines in case of heavy winds to prevent any damage to the installations. In thermal power plants, a typical application is controlling butterfly valves, which reduce the steam pressure quickly and in a controlled way in the event of an emergency. In all of these applications, safety is the top priority. Frequently redundant systems with switching position monitoring are used here which can be precisely adapted to the relevant system together with the customer.
