Introduction to Electrically Actuated Valves (Motor Operated Valve or MOVs)

The two most common methods of opening and closing industrial valves are by pneumatic actuators and electric actuators. This video introduces to viewer to electric valve operation. Commonly known as "motor operated valves", or MOVs, electric operators can be fitted to any quarter-turn valve (90 deg. rotation) (such as a ball, butterfly or plug valve), or linear movement valve (such as a globe or gate valve). Most often electric actuators are used where electric power is readily available and a pneumatic air systems are not. They are available in a variety of voltages and torque outputs for various size valves. Accessories such as limit switches, positioners, and hazardous area enclosures are available as well. Thanks to Tony Kuphaldt and Bellingham Technical College for the video.
