Valve Actuators & Controls: Purpose, functionality, application.

A valve actuator is the mechanism for opening and closing a valve allowing valves to operate remotely, without having people in attendance to manually adjust them. They are often part of an automated system designed to regulate flow, pressure or some other process allowing the system to respond by opening or closing the valve, or setting it to an intermediatry position to reduce or increase flow.

Power-operated actuators, using gas pressure, hydraulic pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves. 

Used for the automation of industrial valves, actuators can be found in all kinds of process plants. They are used in waste water treatment plants, power plants, refineries, mining and nuclear processes, food factories, and pipelines. Valve actuators play a major part in automating process control. The valves to be automated vary both in design and dimension. The diameters of the valves range from one-tenth of an inch to several feet.
