Unlike electric actuators, industrial pneumatic actuators use compressed air to trigger a valve. Because they dont 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 valveRack and pinion actuators, which convert linear action to rotary motionBoth types of pneumatic actuator can be used with different configurations of industrial valve. Which type 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.
