Our more than 100 years of experience also ensures you get access to a high level of product expertise. Our in-depth inventory includes a wide range of electric valve actuators that combine high quality with a low cost of ownership, which can provide a welcome boost to your company’s bottom line.
Electric Actuator Uses & Applications
Actuators perform the essential function of opening and closing valves and can also play a prominent role in the automation of process control. Electric actuators are equipped with an electrically powered motor that offers the advantage of quiet, energy-efficient, pollution-free operation. However, electric actuators can only be used in work environments where a source of electricity is readily available. Electric actuators are commonly used in facilities such as power and wastewater treatment plants and refineries.
Brands
As a SEMCOR customer, you will have access to reliable, precise electric actuators from leading manufacturers such as Bernard, Auma and SVF Flow Controls, Inc. We have forged closed relationships with each of these manufacturers, enabling us to provide the high level of technical support you demand and deserve.
Factors To Consider When Selecting an Electric Valve Actuator
Actuator selection involves evaluating more than simply matching the actuator to the valve. Application requirements, operating conditions, and control objectives all influence actuator performance.
Common selection criteria include:
- Valve type
- Required torque output
- Quarter-turn or multi-turn operation
- Supply voltage
- Duty cycle requirements
- Environmental conditions
- Control system compatibility
- Positioning accuracy requirements
Reviewing these factors early in the project helps ensure reliable operation and proper actuator sizing.
Benefits Of Electric Valve Automation
Electric actuators offer several operational advantages in applications where electrical power is readily available. They can be integrated with automated control systems and configured for specific operating requirements.
Key benefits include:
- Remote valve operation
- Reduced manual intervention
- Repeatable valve positioning
- Integration with PLC and SCADA systems
- Quiet operation
- Reduced utility requirements compared to compressed air systems
- Position feedback capabilities
- Support for automated process control strategies
These advantages make electric actuation a practical solution for many process control environments.
Electric Valve Actuators Frequently Asked Questions
What Is an Electric Valve Actuator?
An electric valve actuator is a motor-driven device that opens, closes, or positions a valve by converting electrical energy into mechanical movement.
What Types of Valves Can Electric Valve Actuators Operate?
Electric valve actuators are commonly used with butterfly valves, ball valves, plug valves, gate valves, globe valves, and other valve types requiring quarter-turn or multi-turn operation.
What Is the Difference Between a Quarter-Turn and a Multi-Turn Actuator?
Quarter-turn actuators rotate approximately 90 degrees and are commonly used with ball and butterfly valves. Multi-turn actuators are designed for valves that require multiple rotations to fully open or close.
