Torque range:30~3000N.m

Material: Aluminum Alloy

What Is Multi-turn Electric Actuator?

A multi-turn electric actuator is an advanced electromechanical device used in industrial settings to precisely control linear motion, particularly for valves that require multiple rotations to fully open or close. Unlike quarter-turn actuators that rotate valves by 90 degrees, multi-turn actuators are designed to execute numerous rotations along the valve stem, enabling precise positioning of linear movement valves such as gate valves, globe valves, and rising stem ball valves.

Comprising components such as an electric motor, gearbox, limit switches, and control circuitry, multi-turn electric actuators offer efficient and reliable operation. The electric motor converts electrical energy into mechanical force, which is then transmitted through the gearbox to generate the necessary torque for valve operation. Limit switches ensure accurate control over the actuator’s movement, guaranteeing precise positioning of the valve. These actuators play a crucial role in industrial automation, enhancing operational efficiency, and safety by enabling remote and automated valve control while minimizing the risk of human error.
