Valves & Actuators

摘要

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling water, chemical treatment, bottom ash and steam turbine control systems. They work in harsh environments and are exposed to a variety of chemicals, abrasive materials and high temperatures. They are critical in optimizing efficiency, and they are often the final control element in the operation of a power plant.
