Overview
There are two basic types of electric valve actuators: rotary and linear. Each type of actuator uses special valves.
Rotary electric valve actuators are used with ball, plug, and butterfly valves that rotate a quarter-turn or more from open to close. Rotary electric valve actuators are used in the electric power industry, high-power switching gears, and packaging applications.
Linear electric valve actuators are used with gate, globe, diaphragm, pinch, and angle valves that feature a sliding stem that opens or closes the valve. Linear electric valve actuators are well-suited for operating in tight tolerances.
