Power Plant Industry
Electric actuators make up a small part of a power plant – 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 process pressure or relieve a pipe system of a certain pressure. Applications include pollution control, feed water, cooling water, chemical treatment and steam turbine control systems.
