Electric actuator?is specifically designed for power-to-open and power-to-close functionality, maintaining the last known position in the event of a power loss. When a continuous voltage signal is applied, the actuator’s heavy-duty motor engages, driving a robust all-metal gear system to rotate the output drive exactly 90°. Internal cams activate limit switches to automatically stop the motor, ensuring precise control. Upon receiving a reversing signal, the motor rotates in the opposite direction, reversing the drive position.

This valve actuator is commonly used to automate quarter turn ball valves, butterfly valves, or dampers and is straightforward to install using its ISO5211 multi-flange mounting and double square drive. Its unique integral motor/housing design delivers higher torque output in a compact form, making it a space-efficient solution for high-power applications.

FAQ

What is an electric actuator?

An electric actuator is a device that uses electrical energy to control the movement of valves or dampers in industrial processes. It converts electrical signals into mechanical motion, allowing systems to operate automatically without manual intervention.

How does an electric actuator work?

Electric actuators use a motor to generate rotational or linear motion, depending on the application. For quarter-turn applications like ball or butterfly valves, the actuator rotates the valve stem 90° by driving its internal gear components. Signals from a control system tell the actuator to open, close, or modulate valve positions precisely.

What are the benefits of using electric actuators over other types?

Electric actuators offer several advantages:
– High precision and reliable control.
– Ease of integration with modern automation systems.
– Cleaner operation without the need for hydraulic fluids or air compressors.
– Low maintenance compared to pneumatic or hydraulic actuators.
– Energy-efficient functionality.

What applications are electric actuators best suited for?

Electric actuators are ideal for applications requiring precise control and automation. Common industries include:
– Chemical Processing – for accurate flow and pressure management.
– Water Treatment – for controlling valve operations in filtration and distribution systems.
– Oil and Gas – for safe handling of flow in pipelines.
– Power Generation – for managing turbines and cooling systems.
– HVAC Systems – for controlling dampers and airflow.

FAQ

What is a pneumatic actuator?

A pneumatic actuator is a mechanical device that uses compressed air to produce motion. It is commonly used to control the movement of valves, such as pneumatic ball valves and pneumatic butterfly valves, in various industrial systems. Pneumatic actuators are valued for their reliability, efficiency, and ability to handle high-cycle operations.

How does a pneumatic actuator work?

Pneumatic actuators operate by converting the energy from compressed air into mechanical motion. When air is supplied, it fills a chamber inside the actuator, causing a piston or diaphragm to move. This movement drives the control mechanism, such as opening or closing a valve, with precision and speed. The motion can be linear or rotary, depending on the actuator design.

What are the types of pneumatic actuator?

Pneumatic actuators are typically categorized by action mode or design style. The main types include:
– Double Acting Actuators: Use compressed air for both opening and closing motions.
– Single Acting Actuators: Use compressed air for one-directional movement and rely on a spring for the return action. This can be configured as normally open or normally closed.
– Rack and Pinion Actuators: Employ a rack and pinion mechanism to achieve rotary motion, ideal for valve operations.
