What is an electric actuator?
There are different types of electric actuators, linear actuators that create linear motion, multi-turn actuators that create rotary motion, or part-turn actuators which are actuators that need less than one full turn to complete a full valve stroke. Actuators can be used to perform various functions, such as moving, positioning, adjusting, regulating, opening/closing, lifting/lowering or turning something, depending on the application and the requirements of the specific system. Electric actuators are used in various applications and industries, such as Water & Wastewater, Energy & Power Industry, Industry & Marine, Oil & Gas and process technology industry.
They offer advantages such as high precision, reliability, versatility and energy efficiency, making them a popular solution in various industries and applications. The control of actuators can vary from simple manual control with, for example, buttons or a handwheel, to more advanced automatic control using sensors and computers or control signals from the control room via standardized control systems.
What is an electric actuator used for?
Electric actuators offer advantages that make them a popular solution in various applications and industries.
- Precision: Electric actuators offer high precision when it comes to motion and position control. They can perform precise and repeatable movements, which is crucial in many applications where precision is important, such as automation.
- Versatility: Electric actuators can be used in a variety of industrial automation applications. The most common application is some form of valve, hatch or louvre damper. They are modular and can be adapted to suit different requirements and needs.
- Energy efficient: Electric actuators are energy efficient and contribute to reducing energy consumption and require less service and maintenance than alternative solutions. It results in reduced operating costs and reduced environmental impact – which is beneficial from both an economic and environmental perspective.
How does an electric actuator work?
An electric actuator works by converting electrical energy into mechanical motion using an electric motor.
