Quarter-turn electric actuators are valve drive devices powered by electric motors, which drive the output shaft to rotate at a limited angle of 0°～90° (or 0°～180°) through reduction transmission mechanisms. Featuring compact structure, fast response, small size and easy installation, they are suitable for quarter-turn valves such as ball valves, butterfly valves and plug valves. Widely used in petroleum, chemical, power, metallurgy, water treatment and other industries, they can realize on-off control, proportional adjustment and bus communication, meeting the requirements of automatic systems for fast opening/closing and precise regulation of valves.
