Wholesale Industrial Electric Valve Actuator

Multi-turn electric actuators are an important driving device in the field of industrial automation. They can provide more than 360 degrees of rotation and are mainly used to control valves that require multiple turns, such as gate valves, stop valves, etc. The following are some key features and functions of multi-turn electric actuators:
Intelligent and digital: Multi-turn electric actuators usually use advanced ultra-large-scale integrated circuits and have the characteristics of intelligence and digitalization.
Drive mode: They are driven by a three-phase asynchronous motor, which drives the hollow output shaft to output torque through a worm gear reduction.
Manual/electric switching: It has a manual/electric switching mechanism that allows handwheel operation in the manual position and automatically switches to the electric position when the electric operation is performed.
Control accuracy: The intelligent controller of the actuator can accept standard analog current control signals, switch control signals or bus signals to achieve precise valve position and torque control.
Torque protection: Equipped with a classic mechanical torque protection device to ensure stable and reliable operation.
Non-intrusive design: It has a double seal structure and a shell without a through shaft design, with a high protection level and strong adaptability.
Versatility: It can be used with accessories such as electric drives and position transmitters to realize the functions of automatic control devices.
Structural type: Multi-turn electric actuators can be equipped with a primary reducer to convert them into angular travel or linear travel electric actuators, increase the output torque, and slow down the movement speed.
Wide application: It is suitable for occasions where the load torque remains unchanged or does not change much. If the torque control part is added, it can adapt to a wider range of application needs.
Selection of electric actuators: When selecting, factors such as valve type, torque size, and stroke need to be considered, and a certain margin should be reserved to ensure safety and reliability.
Multi-turn electric actuators play an increasingly important role in the field of modern industrial automation due to their high efficiency, stability, and easy integration.

Quarter-turn electric valve actuator is an electric actuator designed to control valves that require partial angle rotation, such as butterfly valves, ball valves, plug valves and dampers. Here are some key features and applications of partial-turn electric actuators:
Working principle: Partial-turn electric actuators receive signals from regulators or control systems to drive valves to open, close or adjust control within an angle range of 0 to 90 degrees or less.
Compact structure: This type of actuator is usually designed to be compact and can be installed on smaller valves, suitable for applications with limited space.
Precise control: They provide precise positioning capabilities, can accurately control the opening of the valve, and achieve precise flow control.
Integrated design: Partial-turn electric actuators often adopt an integrated transmission mechanism design, making the product smaller and simpler in appearance.
Easy operation: It has a fully automatic manual/electric switching function, which is easy to operate and can be manually operated without switching the handle.
Protection level: It has a good protection level and can adapt to a variety of working environments, including explosion-proof type, integral switch type, integral adjustment type, etc.
Wide application: Suitable for a variety of control systems and working environments, and can achieve automated control in different industrial applications.
Technical standards: The design and manufacture of part-turn actuators follow the requirements of ISO5211 standards to ensure compatibility and reliability with valves.
Torque output: Although the output torque of part-turn actuators is usually smaller than that of multi-turn electric actuators, it is sufficient to meet the needs of angular stroke valves.
Safety: Safety is taken into consideration in the design to avoid damage to the valve by axial thrust and ensure the safety of valve operation.
Due to its flexibility and adaptability, part-turn electric actuators play an important role in the field of industrial automation and process control, especially in applications where precise control of valve opening is required.

A linear actuator is a device used in industrial automation that converts received electrical signals into linear motion, thereby driving valves or other actuators to open or close. Here are some key features and applications of linear actuators:
Working principle: A linear actuator receives a DC signal (usually 0-10V or 4-20mA) and converts it into a linear motion corresponding to the input signal.
Various control methods: They can be continuously adjusted, manually remotely controlled, and manually operated on the spot, providing flexible control options.
Technical parameters: Linear actuators have different models to meet different needs, including different supply voltages, power consumption, input signals, feedback signals, rated strokes, operating time, and thrust.
Environmental adaptability: Designed to adapt to different working environments The temperature and humidity range ensures stable operation under various conditions.
Safety features: CE certification and electrical protection level, as well as a certain protection level, such as IP54, ensure safe use.
Material selection: The upper cover may be made of PC plastic, the shell may be plastic or cast aluminum depending on the model, and the bracket is usually cast aluminum to ensure durability and reliability.
Feedback signal: It can provide position feedback signal, such as DC 0-10V or 0-20mA, to ensure precise control.
Application field: It is widely used in the regulation system of power plants, steel, petroleum, chemical industry, light industry and other industrial sectors to accurately control the opening of the valve.
Protection function: Some models have protection functions such as overload protection, temperature protection and compression spring to ensure the valve is closed tightly.
