Frequently Ask Questions
A Multi-Turn Electric Actuator is an electrically powered actuator that produces multiple rotations of its output shaft to operate valves requiring several turns for opening and closing.
Yes. Modulating models can provide intermediate valve positioning and flow regulation, commonly using a 4–20 mA control signal.
Alis Valves manufactures and supplies Multi-Turn Electric Actuators for automated Gate Valves, Globe Valves, and other industrial multi-turn valve applications.
A multi-turn actuator rotates through several turns, while a quarter-turn actuator rotates approximately 90° and is commonly used for Ball and Butterfly Valves.
Yes. With the appropriate thrust unit or actuator configuration, it can generate the linear thrust required for valves such as rising-stem Gate and Globe Valves.
An On-Off actuator is primarily used to move the valve between open and closed positions, while a modulating actuator can position the valve at intermediate points for flow control.
