Electric Actuator
Product Features
Basic composition and working principle
The electric actuator consists of three parts: the drive part (including the reducer), the output shaft and the matching interface. The input end usually uses DC 24V or AC 220V regulated power supply, and the output end uses the built-in gear box to carry the overall rotation angle display instrument and connect the hydraulic/air source or power supply to the valve for interlocking operation. It can realize the monitoring of the operating status and command input through a series of components such as independent control instruments, linear push rod position sensors, and connecting accessories. Intelligent characteristics and application fields.
The electric actuator has the following characteristics:
Easy installation: it does not require a large number of additional facilities, can be flexibly arranged according to site requirements, and is suitable for complex environmental conditions.
Simple structure: uses DC or AC motors as torque transmission elements, with reasonable design, small size and weight.
High degree of intelligence: outputs various control commands after PLC calculation, supports RS485 communication protocol, and provides good data solutions.
Wide adjustment range: during operation, the power size and rate conversion can be flexibly adjusted according to actual needs.
Electric actuators are widely used in the following fields:
Petroleum and natural gas industry: used for various valve controls in pipelines, storage tanks and other fields.
Chemical industry: mainly used for the switching and adjustment of various reactors, furnaces, distillation towers and other important facilities.
Power machinery and automobile industry: such as the operation of generator sets, compressor systems and automobile fuel tank caps.
Other fields: such as pharmaceutical production, cleaning of liquid packaging bags, etc.

Main features
Mechanical end stop
• Electric actuators are equipped with adjustable mechanical stops to prevent possible overtravel during manual operation.
Position indicator.
•Visual position indicator can clearly indicate the current valve position. Infact, this indicator is mechanically connected to the valve shaft.
Travel limit switch
• Thanks to the cam block system, travel limit switch adjustment can be done with only a standard screwdriver. No special tools are required.
• Each cam can be set independently of the others.
•The cams are automatically locked in their respective positions, and once adjusted, are not affected by vibration.
Asynchronous motor
• Asynchronous motor technology provides the highest ratio of starting torque to nominal torque. Therefore, the maximum torque capability of the actuator is available to unseat the valve from the beginning of the stroke.
Motor thermal protection
•Built-in motor temperature switch can prevent the motor from overheating.
Removable drive bushing
• The output drive sleeve can be easily removed from the actuator without the use of any special tools to accommodate the valve shaft.
Lubricating
• Gears are designed to ensure a lifetime of grease lubrication, which greatly reduces the need for periodic maintenance
Extensive control options
Standard controls
The customer provides the control logic to process all data received from the actuator electrical contacts. The mains reversing starter is installed in the customer's own cabinet.
Integral control
The integral control system is fully configurable and can perform all actuator control functions including generating status reports, fault handling, protection systems and command processing. It provides local control that can be disabled locally or from a remote location. The reversing starter is integrated in the control unit.
Positioning control
The positioning control is based on the same electronic platform, but includes a positioning function. Proportional signals are used to control the actuator (setpoint) and signal the actual position of the valve (feedback).
SRA6 electric actuator
