Actuator Valve
Having the right equipment for the job is essential to operations, and actuator valves are a crucial component of many facilities ‘ daily work requirements. Work with SEMCOR to get the equipment you need to optimize your work processes.
Industrial Actuators and Controls
Actuators play an important role in today’s automated facilities by allowing plants to have valves that are automated and can be controlled remotely. Based in St. Louis, SEMCOR has one of the largest local inventories of industrial actuators and valves in the Midwest. When you work with us, you are working with a team that can help you make smart choices, and that will be there to provide local support whenever you need it.
We sell pneumatic and electric actuators made by some of today’s most trusted manufacturers. We also carry a number of accessories, including our own brackets and damper drives. We can provide a complete automation solution for your facility.
For highly specialized applications, we are able to modify or fabricate an actuator that will work with your processes. Our team has the industry experience and the problem-solving expertise necessary to find creative solutions to any liquid handling challenge. Whether your business is manufacturing, oil and gas processing, food and beverage or anything else, make us your first call when you need an industrial actuator or automated valve supplier in the St. Louis area.
Industries We Serve
If you work in an industry that uses valves to regulate processes, you know that it’s essential to have the right equipment for the job. Some of the industries that most commonly use this equipment include:
- Energy and power industry: As rising industrialization leads to increased demands for power, the energy and power industry relies on actuator controls to complete critical operations.
- Water and wastewater industry: Automated valves are an essential component of operations at water and wastewater treatment plants. They play a key role in monitoring and managing the flow of fluids through pipelines.
- Oil and gas industry: The oil and gas industry must adhere to strict regulations to reduce air pollution, heightening the importance of efficient, effective valves and actuators.
Types of Valves Available
As the component in a pipeline that controls the opening and closing of the valve, the right actuator is essential to efficient operations and flow management. We offer two main types of valves to work with your processes — pneumatic actuators and electric actuators.
Whether you need an actuator to work with butterfly valves, ball valves, check valves, gate valves or a variety of other valve classifications, SEMCOR can help you find the right actuator controls for your operations.
Pneumatic Actuators
Unlike electric actuators, industrial pneumatic actuators use compressed air to trigger a valve. Because they don’t require an external power source, they are a convenient choice for a number of applications. Each type of actuator has its advantages and disadvantages. The specifics of the application will determine which one is the best choice.
Pneumatic industrial actuators are generally classed into one of two categories:
- Rotary actuators, which use a series of vanes produce a rotational motion that operates a valve
- Rack and pinion actuators, which convert linear action to rotary motion
Both types of pneumatic actuator can be used with different configurations of industrial valves. Which type of actuator your application requires depends on a number of specifics, including pressure and flow rates, and the specific product being handled. SEMCOR has partnered with leading manufacturers including Kinetrol, whose pneumatic industrial actuators are guaranteed to provide at least four million cycles. Contact our office today for more information about our current inventory.
Electric Actuators
Electric actuators are used to remotely trigger and control the valves that stop or limit the flow of liquid through a pipeline. Electric actuators can be used with butterfly, ball, globe and other types of valves — matching the right product to the right valve requires a careful consideration of a number of different factors. SEMCOR’s sales engineers are available to help you make an informed choice. We supply products by AUMA, Bernard and other manufacturers — contact our office directly for more information.
Automation Integration Support
Modern facilities rely on coordinated automation systems that connect actuators, sensors, and control platforms into a unified operational framework. SEMCOR supports these environments by helping teams evaluate how actuator selections influence system responsiveness, communication protocols, and long term reliability. Many plants operate mixed technology environments, and integrating new actuators into legacy systems requires careful planning. SEMCOR assists with compatibility reviews, mounting configurations, torque requirements, and signal interface considerations to help ensure that new components align with existing control strategies. This guidance helps facilities reduce commissioning time and maintain consistent performance across their automated processes.
Selection Factors for Actuator Sizing and Performance
Choosing the right actuator involves more than matching a torque rating to a valve. Procurement teams often evaluate environmental conditions, duty cycles, media characteristics, and maintenance expectations before finalizing a selection. SEMCOR helps customers assess these variables by reviewing application data such as temperature ranges, cycle frequency, available utilities, and enclosure requirements. This approach supports informed decision making and helps ensure that actuator performance aligns with operational demands. By considering these factors early in the sourcing process, facilities can reduce unexpected downtime and extend equipment life.
Maintenance Planning and Lifecycle Management
Actuators play a continuous role in process control, making lifecycle planning an important part of plant reliability. SEMCOR assists customers in developing maintenance strategies that include inspection intervals, spare parts planning, and performance monitoring. Understanding how actuators behave over time allows facilities to schedule service proactively rather than reactively. SEMCOR’s support helps teams identify early signs of wear, evaluate replacement timelines, and maintain consistent operation across critical systems.
