Our pneumatic rotary actuators are supplied from one of the world’s leading pneumatic component manufacturers, Aventics.

What is a rotary actuator

A rotary actuator is a device that creates a rotary movement by using a shaft to control the speed and rotation of attached equipment, such as valves. Rotary actuators can produce either continuous rotation or movement to a fixed position, depending on what application they are servicing. The most common rotary actuators are electrically powered but you can also get pneumatically or hydraulically powered devices.

Rotary actuator applications

Rotary actuator applications can range from air core gauges to valve actuators that operate a pipeline and process valves. Rotary actuators are used in a wide variety of process applications including medical & laboratory, food & beverage and almost any application that requires a rotary motion.

MGA Controls are proud partners with Aventics, a market leader in pneumatic components and instrumentation. Formerly known as Bosch Rexroth, Aventics supply a comprehensive range of Pneumatic equipment that has been painstakingly designed to cover almost any application.

Aventics pneumatic rotary actuators are available in a range of bore sizes depending on the load they need to move and are available with 90°, 180°, 270° and 360° strokes. They can also be fixed or adjustable, so very precise movement can be achived.

With a wide range of models, sizes and additional features available, MGA Controls can provide advice on the right rotary actuator for your application. To discuss your rotary actuators applications, contact us today on 01704 898980 or email sales@mgacontrols.co.uk. For further information, you can take a look at our rotary actuators PDF below.


Rotary actuators work by converting compressed air into an oscillating rotary motion. This then allows for either a continuous rotation or movement to a fixed position, depending on what application the actuator is servicing.

The Aventics TRR Series is a rotary pneumatic cylinder that operates by using a rack and pinion system. It is a highly reliable unit that can be ordered with either 90, 180 or 360-degree angles of rotation.

Key features include:

  • Rack & pinion actuator
  • 32mm to 100mm Bore
  • 90, 180 or 360-degree strokes
  • Magnetic piston
  • Double piston with rack
  • Pneumatic adjustable cushioning
