Multi-turn actuators, also known as multi-turn valve actuators or multi-turn electric actuators, conform to the ISO 5210 standard. These actuators are designed to withstand the thrust applied to the valve and transmit torque to the valve for at least one full revolution. Typically, multi-turn actuators require more than one revolution. Therefore, gate valves are commonly equipped with rising valve stems, operated based on several rotations performed by multi-turn actuators. For these applications, multi-turn actuators are equipped with a hollow shaft to accommodate the rising valve stem.

Reliability is the name of the key in industrial automation. Multi-turn electric actuators take this seriously. They are built to withstand the test of time, offering consistent performance even in the harshest environments. 
To stay ahead in the automation industry, you need advanced control systems. Multi-turn electric actuators come equipped with state-of-the-art technology. They are easily integrated into your existing systems, allowing for seamless control and monitoring.

Fluid Control

In chemical processing plants, multi-turn actuators control the flow of chemicals through pipelines. They open and close valves to control the flow of chemicals and adjust valve positions to maintain a constant flow. The feedback system on the actuator ensures the valve operates correctly.

Water Treatment and HVAC:

In water treatment plants, multi-turn actuators control the flow of water through a series of pipelines and valves. They open and close valves to control water flow and adjust valve positions to maintain a constant flow. The feedback system on the actuator provides information about the valve position to ensure proper operation.

Industrial Machinery

Design and Operation of Multi-turn Actuators:

Multi-turn actuators are typically powered by electric motors that generate the torque required for a rotating output shaft. The output shaft is connected to a gear mechanism, where gears increase torque and provide the necessary rotation.

The gear mechanism commonly includes worm gears for electric actuators and spur gears for hydraulic and pneumatic actuators. Worm gears are often used in electric actuators, while spur gears are more common in hydraulic and pneumatic actuators. Worm gears offer lower speed with higher torque, while spur gears can provide higher speed at the expense of lower torque.

The gear mechanism is connected to a position feedback system that provides information about the actuator's position. Position feedback systems can be based on potentiometers, rotary transformers, or encoders. A reliable feedback system is crucial for ensuring accurate and repeatable positioning of the actuator.
