Pneumatic Actuator Uses & Applications

Actuators are mechanical devices that enable the opening and closing of valves. Pneumatic actuators rely on air or gas pressure to produce the opening and closing action via linear force that is supplied to the valve stem. Pneumatic applicators are specifically designed for tasks requiring precise control with frequent valve opening and closing that could place undue stress on electric actuators. This type of actuator is ideally suited for applications involving high temperatures or where the risk of explosion is great, as it contains no motor that could create magnetic interference.


SEMCOR is proud to distribute pneumatic actuators produced by highly regarded manufacturers such as Kinetrol. As part of our quest to provide the best service to our customers, we also provide access to reliable technical support for every actuator we sell.
