PR series

Maximum modularity & corrosion resistance

The established rack-and-pinion design of our PR series actuators ensures a durable and reliable application in continuous operation even under the toughest conditions and has been the key to process reliability for decades. It enables the highest possible torque output in combination with a compact and weight-saving design.

Due to the design with internal slide bearings, the actuators of the PR series are absolutely maintenance-free. The requirements for easy maintenance are also fully met thanks to the actuator principle and the captivated safety springs. Thanks to the consideration of all common market standards for the connection interfaces, the actuator series PR offers highest modularity when combined with valves and accessory components such as control valves, limit switches or positioners. Due to the use of high-quality aluminum alloys and an additional powder coating, the actuators have a maximum of corrosion resistance and can be used without any problems even in demanding environmental conditions.
