Valves and actuators: Changing demands on power plants

Valves and actuators make up a small part of a power station – perhaps only two or three per cent by capital cost – but they play a vital role. A large power plant uses hundreds of valves to manage flows of water and steam. Valves may be used to stop and start flow, reduce or increase flow, control the direction of flow, regulate a flow or ...
