Valve Basics: Electric Actuator Controls
Electric valve actuators control the opening and closing of valves. With a motor drive that provides torque to operate the valve, these actuators are frequently used on multi-turn valves such as gate or globe and also on ball, plug and other quarter-turn valves.
