What is Multi-Turn On-Off Electric Actuator?

A multi-turn electric actuator is a type of electrical device used to control the movement of a valve or other mechanical component. It typically consists of an electric motor, gear train, and screw or rack and pinion mechanism. The electric motor is used to rotate the gear train, which in turn rotates the screw or moves the rack and pinion, creating linear motion. Linear motion is then used to open or close a valve or other mechanical component.

On-Off electric actuators are a type of electric actuator designed to operate in the “open” or “closed” state. They are typically used to open or close a valve or other mechanical component in the fully open or fully closed position.

Where is Multi-Turn On-Off Electric Actuator Used?

Multi-turn electric actuators are typically used in applications where precise and reliable control of valve movement is required, such as the control of process fluids in industrial environments. They are often used in conjunction with control valves used to regulate the flow of fluids in a process. Multi-turn electric actuators are also used in a variety of other applications, including HVAC systems, water treatment plants and power plants. Actuators are also widely used in the power generation industry, metallurgy, petroleum, chemical, paper, manufacturing and refining industries, with their smaller size and light weight and easy maintenance features compared to manual handwheels. On-Off electric actuators are commonly used in applications where dual control (i.e. on or off) is sufficient and precise control of valve movement is not required.

General Structure

Electric Actuators; It consists of 3-phase motor, speed regulator, torque control, stroke control opening indicator, manual electrical switches, manual gear and electrical parts.

Torque Setting

The actuator contains a mechanically adjustable torque mechanism. The necessary torque control settings have been made at the factory. However, if adjustment is still needed, it can be done mechanically.
