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:

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:

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.

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.
