From conventional thermal power stations through to biomass, hydroelectric, geothermal and combined heat and power (CHP) facilities, automated valve control is fundamental to safe, efficient and reliable operation. While turbines, boilers and generators often receive the greatest attention, the performance of every power plant also depends upon the precise control of water, steam and auxiliary process systems.
Electric actuators play a central role by converting control signals into accurate valve movement. Installed on isolation and modulating valves throughout a plant, they regulate the movement of water, steam and other process media while providing repeatable positioning and dependable operation over long service lives.
Modern power stations operate increasingly sophisticated distributed control systems (DCS), requiring field devices capable of seamless integration. AUMA electric actuators are designed with interfaces compatible with plant control systems, allowing operators to monitor valve position, operating status and diagnostics from the control room. This improves operational visibility while supporting planned maintenance strategies.
Power generation environments can also present demanding operating conditions, including elevated temperatures, vibration and varying electrical supply conditions. Electric actuators specified for these applications must be engineered to maintain consistent performance while providing reliable operation across different mounting positions and valve types. AUMA designs its actuator platforms specifically for these demanding environments.
As operators continue extending plant life while improving efficiency, actuator modernisation has become an increasingly important consideration. Retrofitting ageing actuation systems with modern intelligent electric actuators can improve operational control, increase diagnostic capability and support digital asset management without replacing the existing valve.
For engineers specifying new power projects or upgrading existing assets, electric valve actuation should be viewed not simply as a mechanical accessory but as a critical automation component that contributes directly to plant reliability, availability and long-term operational performance.
