An overview article on Actuators
#1
<p>An overview article on Actuators<br><br>&nbsp; &nbsp; An actuator is a type of motor, typically operated by electric current, hydraulic fluid or air pressure that&amp;#39;s widely used in the Process Industry for moving or controlling a mechanism or system.<br><br><br>&nbsp; &nbsp; <br><br><br><br>&nbsp; &nbsp; How do actuators work?<br><br><br>&nbsp; &nbsp; Actuators take fluid, electric or some other source of power and convert it through a motor, piston or other devices to perform work. Basic versions are used to move Actuated Valves to either fully opened or fully closed positions. While actuators for control or position regulating valves are given a positioning signal to move to any intermediate position with a high degree of accuracy.<br><br><br>&nbsp; &nbsp; <br><br><br><br>&nbsp; &nbsp; Actuator types<br><br><br>&nbsp; &nbsp; There are four main types of actuators that are a combination of the type of power applied and the type of movement required at the valve.<br><br><br>&nbsp; &nbsp; Pneumatic Actuators are one of the most common and dependable configurations of actuators and are capable of quickly operating very large valves. The main advantage of this type of actuator is that all of the accessories are incorporated in the package and are physically and environmentally protected. It has all the basic and advanced functions incorporated in a compact housing which can be watertight, explosion-proof and in some circumstances, submersible.<br><br><br></p>
